Pratica di Shadowing: Why did white men conquer the world? - Impara a parlare inglese con i video

How did Europeans conquer the world?

I hear a lot of talk and complaints about colonialization.

But why didn't Africa or the Americas colonialize Europe instead of the other way around?

Here's a crazy example.

In 1532, Francisco Pizarro and fewer than 200 Spanish conquistadors marched into modern-day Peru.

They faced an Inca empire with an army of 80,000 warriors with millions of residents, using cannons, horses, and steel,

the Spaniards attacked in a way the crowd had never seen.

Within hours, they had slaughtered 7,000 Inca and captured the Emperor Atahualpa without losing a single man.

Within a generation, the entire empire fell.

This wasn't a one-time fluke.

The pattern repeated itself on multiple continents.

One side had steel, swords, guns, horses, ocean-going ships, writing system, and centralized kingdoms.

The other side had stone and wooden weapons, no writing, no metal tools, and fragmented political structures.

Why?

I'm Ken LaCourt.

I do my best here to look at uncomfortable topics and give you a balanced overview.

It's not about judging, it's trying to understand reality best we can.

For my videos, I usually compile information from hundreds of sources, but this one is different.

I took it from one, a wonderful book by Jared Diamond called Guns, Germs, and Steel.

It's possibly the best book I've ever read, and it reshaped how I view the world.

I hope I do it justice.

He tackled the central question, why did Eurasia, the regions of Europe, Asia, and North Africa become so successful?

And he argues that it's not about intelligence or genetics, but geography.

In this video, we'll look at a geographic lottery that determined which societies would dominate.

We'll see how some areas hit the plant and animal jackpot, and how the resulting surplus builds empires.

Finally, we'll look at the invisible weapon that killed more people than guns and swords combined.

So to understand how some tribes won the geographic lottery, we need to rewind the clock to about 11,000 BC.

At that point, humans everywhere were remarkably similar.

There were homeosapiens who had basically had the same brains, the same cognitive abilities, and the same potential.

Yeah, there were minor differences like skin color, body type or adaptations to local climates,

but a baby born in Europe had no built-in advantage over a baby born in Australia or the Americas or Africa.

Everyone was a hunter-gatherer, following game, gathering plants, and living in small bands of people who moved with the seasons.

So if everyone started at roughly the same place, how did things diverge so dramatically?

So look, I did a video recently on Africa, why it's still behind much of the world, despite billions of dollars of help.

And a lot of the comments were just like, well, they simply have lower IQs and they'll never catch up.

But modern IQ tests measure abstract reasoning, literacy, and mathematical concepts taught in schools.

They were designed by academics and countries to predict success in industrialized education systems.

Diamond spent years working in New Guinea.

And one thing that struck him immediately was that people there were exceptionally observant, inventive, and mentally sharp.

Survival demanded it.

You had to know which plants were poisonous, how to read the weather, how to track animals, and mistakes would get you killed.

If you gave a New Guinean farmer an IQ test designed for an American suburb, he'd bomb.

He'd never seen the references or types of problems that it assumes.

But if you gave a Harvard graduate a New Guinea IQ test

and made him track an animal through the forest or navigate without a GPS, he'd probably be toast too.

Diamond's conclusions were clear and persuasive.

Geography determines which societies can develop agriculture, and agriculture determines everything that comes after.

The societies that figured out agriculture got a massive head start by thousands of years.

By the time the Europeans crossed the Atlantic with guns and steel, they had a 5,000-year advantage.

But why couldn't hunter-gatherers just catch up and develop their own complex civilizations?

Because nomads, they have to stay mobile.

They follow herds and track seasonal plants.

If food moves, they move.

And that mobility creates brutal constraints.

One is essentially that everyone is in food gathering mode.

Calories are tough to come by and they take a tribe's time and effort.

And when you're constantly on the move, you can't accumulate possessions.

You can't store food long term.

Everything you own has to be carried on your back.

That means no heavy pottery or tools or building materials.

A nomadic mother, she can only carry one child while she's also gathering food and hauling possessions.

So hunter-gatherer women spaced births out about four years apart.

Settled farmers spaced births out about every two years.

That's half the population growth rate right there.

Over centuries, that difference compounds into massive population gaps.

Or think about injuries.

If you break your leg in a settled farming village, you heal.

You break your leg as a nomad, and you're a burden that the band can't afford.

Either they leave you behind or the whole group slows down and risks starvation.

The same goes for the elderly or the sick.

And forget about developing more complex technology that requires time to tinker, experiment, fail.

It just doesn't work.

It's time you don't have when you're spending every day searching for food.

So the first societies to stop moving were the first to start building.

Agriculture allowed people to settle down and stay in one place, to accumulate surplus food, and that surplus food changed everything.

Now, you might be thinking, okay, so why didn't everyone just figure out agriculture at the same time?

How hard can it be to plant some seeds?

As it turns out, it's really hard.

But before we get to that, I want to talk about a modern day problem and about today's sponsor for a minute, because this is something I think a lot of us have been thinking about lately, inflation.

Did you know that since 2020, inflation has dropped the value of what we saved by about 22%.

And here's the thing that most people miss.

Retirement counts, for the most part, are 100% in the stock market.

During the 2008 financial crisis, stock portfolios got destroyed, but gold increased in value.

It doesn't depend on the decision of a CEO or a company's quarterly earnings, gold is a real-life asset, not just numbers on a spreadsheet.

And that's where today's sponsor, Augusta Precious Metals, comes in.

They've been around for over a decade, and they're known for education, not sales pressure.

They help you understand how gold IRAs work, how you can roll over your existing IRA or a 401k into physical gold without tax penalties.

You're not buying shares of gold, you're buying physical gold bars or coins

that sit in a secured depository under your name and your gold IRA gets the same tax advantages as a traditional IRA.

And Augusta Precious Metals is A-plus rated with the Better Business Bureau.

They'll walk you through everything in simple steps and handle most of the paperwork.

Okay, so back to planting food and building civilizations.

So agriculture just didn't happen everywhere at once.

It happened in a handful of specific places.

100

And those places shared something important.

101

They all hit the plant and animal jackpot.

102

Most wild plants are garbage for farming.

103

They're inedible, poisonous, or so low in calories that they're just not worth the effort to cultivate.

104

Out of the hundreds of thousands of plant species on Earth, only a few dozen ever made good crops.

105

And the Fertile Crescent had a whole bunch of them.

106

The region, stretching from modern-day Egypt through Israel, Lebanon, Syria, and down into Iraq and Iran, it held wild wheat, barley,

107

peas, and lentils growing naturally.

108

And those weren't finicky plants.

109

They had large seeds, predictable growth cycles, and they could be replanted easily.

110

China got pretty lucky too.

111

They had rice and millet.

112

They were both solid crops that could support dense populations.

113

The Americas eventually developed corn, but wild corn called teosinte was basically useless.

114

It's scraggly grass with tiny kernels, and it took Native Americans 3,000 years of selective breeding to turn it into something that resembled modern corn.

115

Think about that for a second.

116

While one group of humans spent thousands of years slowly improving a single crop, people in the Fertile Crescent were already building cities.

117

Sub-Saharan Africa had sogram and yams.

118

They were decent crops, but Africa had fewer plant species to choose from overall.

119

And the Sahara Desert created a massive barrier that slowed the spread of agriculture and information from the Fertile Crescent.

120

Astroya essentially got nothing that could be farmed.

121

Here's how lopsided this lottery was.

122

33 of the world's 56 most valuable wild grasses grew in the Fertile Crescent.

123

That's why agriculture started there first.

124

They had the raw materials.

125

But plants are only half the story.

126

Animals matter just as much, maybe more.

127

And similar to plants, there are lots of species, but only a few are easy to grow.

128

Throughout all of human history, only about 14 large mammal species have ever been successfully domesticated.

129

And there are strict requirements for why some animals can be tamed and others can't.

130

It has to grow fast and breed in captivity.

131

It needs a calm enough disposition so it won't kill you.

132

And it needs to live in a social hierarchy that humans can exploit.

133

Basically, the animal has to recognize a pecking order, and you need to be able to slot yourself at the top.

134

Again, Eurasia hit the jackpot.

135

Sheep, goats, pigs, cattle, horses, donkeys, camels.

136

That's seven of the big 14 species right there.

137

The Americas had llamas and alpacas.

138

That's it.

139

And only in South America.

140

North America, Africa, and Australia, zero.

141

And it's not like people didn't try.

142

Native Americans desperately wanted to domesticate bison.

143

Africans tried with zebras and antelope, but it just didn't work.

144

So why couldn't they domesticate bison?

145

I mean, they don't seem all that different from cattle, but they are.

146

When cattle are threatened, they bunch together.

147

It's a defensive strategy that makes them manageable.

148

Bison panic and stampede.

149

Try to pen them in, and they'll trample you or each other.

150

Zebras?

151

They look like nice stripy horses, but they're vicious.

152

They bite, and they don't let go.

153

They can kick hard enough to kill a lion.

154

Even in modern times, with all our knowledge and tools, we still can't domesticate zebras on a broad scale.

155

Horses are skittish, but they're trainable.

156

Zebras, they just aren't wired that way.

157

So this wasn't a failure of effort or ingenuity.

158

It was biology.

159

It was luck.

160

Some animals can be domesticated.

161

Most can't.

162

And geography shaped one more crucial advantage as well.

163

Eurasia runs east-west.

164

And you can travel 5,000 miles from Portugal to China and stay in roughly the same latitude.

165

That means the same climate, the same growing season, and the same day length.

166

Wheat domesticated in the Fertile Crescent could be spread to Europe, India, and China.

167

Farmers didn't have to reinvent agriculture, but they could take what worked in one place and plant it somewhere else.

168

Africa and the Americas, they run north-south.

169

You know, try taking corn from Mexico and plant it in Canada.

170

It just doesn't work.

171

They have different growing seasons and climates.

172

Crops hit a different climate zone barrier, and they stop spreading.

173

Africa has the same problem, especially with the Sahara Desert, cutting it right in half.

174

It means thousands of years of lost agriculture knowledge that never spread.

175

So while Eurasian farmers were swapping seeds and sharing innovations across an entire continent, America and African farmers, they were stuck starting from scratch.

176

It's a geographic orientation problem, and it's massive.

177

Okay, so once agriculture takes hold, everything changes because now there's a food surplus, and that surplus, it builds empires.

178

When 20 farmers can feed a hundred people, that changes everything.

179

When they could, then for the first time in their history, not everyone needed to spend their day hunting for food and gathering plants.

180

Surplus gives you extra calories and extra time.

181

It creates specialists.

182

In a hunter-gatherer band, everyone hunts and gathers.

183

There's no room for a guy who sits around thinking about better ways to make tools.

184

But once you have agriculture, you can afford to have people who don't produce food.

185

In fact, one of the first things you need

186

when you have a surplus food is a way to store it, something permanent.

187

Then you want guys to guard the food from animals or other tribes.

188

Someone needs to organize and decide how and when to distribute the food.

189

And the basics of government start to emerge.

190

Later in development, professional armies conquer their neighbors.

191

And those conquests bring in more land, more resources, more people.

192

Civilization grows.

193

And here's where political structure becomes crucial.

194

Innovation spread.

195

Eurasia was fragmented in a way that actually helped ideas spread.

196

It wasn't one giant unified empire, but competing kingdoms and city-states and feudal territories connected by trade and migration.

197

When one kingdom invented something useful, like better plows, bronze weapons, or gunpowder, that knowledge didn't stay contained, it spread in multiple ways.

198

Essentially, it was adapt or die.

199

Merchants carried innovations along routes connecting competing kingdoms.

200

Craftsmen and inventors, they moved between territories, bringing their knowledge with them.

201

And with important technology, you either adapted or someone took you over with it.

202

And the east-west axis of Eurasia meant those innovations could travel thousands of miles without hitting climate barriers.

203

Gunpowder invented in China reached Europe.

204

Steel-making techniques developed in the Middle East spread to India and Europe.

205

The Americas didn't have that same political structure or connectivity, so innovation stayed local.

206

The Maya developed writing, but it never spread to the Inca or the Aztecs.

207

Each civilization was reinventing the wheel, sometimes literally.

208

But China had the problem of too much unity.

209

When China's emperor decided to halt oceanic exploration in the 1400s, that decision stuck for the entire huge empire.

210

In Europe, when one kingdom stopped exploring, others continued.

211

Spain's rivals couldn't afford to let Spain monopolize the new world.

212

And technology, well, it kind of builds on itself.

213

So Eurasia moved from stone tools to copper, to bronze, to iron.

214

So when Cortes arrived in the Americas in the 1500s, the Aztecs were still in the Stone Age, literally.

215

I mean, they had obsidian blades, which weren't terrible, but against steel swords, it wasn't even close.

216

But it wasn't because the Aztecs were dumb or lazy, it was because they started late.

217

They didn't have the 5,000 year head start that Eurasia had.

218

The Fertile Crescent got agriculture around 8,500 BC.

219

Mesoamerica didn't get it until around 3,500 BC, 5,000 years.

220

Now, put it in modern terms so that we can see how impossible this gap was to overcome.

221

Imagine us here in the United States being attacked by a civilization just a hundred years younger than us.

222

Think of 1926 US Army attacking modern day America.

223

It would be almost laughable and it wouldn't be a fight.

224

Now do the reverse.

225

Try to imagine a society advanced 5,000 more years into the future attacking us

226

and how our military would fare against that or anything.

227

I mean, I can't even fathom what that might look like.

228

That's the situation that the Incas and the Native Americans and the Africans faced when Europeans arrived.

229

They were fighting enemies that were millennia ahead of them.

230

But the most fearsome thing the Europeans brought to the Americas wasn't guns or steel swords or horses.

231

It was germs, Europe's invisible and unintentional weapon.

232

And the devastation was almost unimaginable.

233

Scholars generally agree that over 90% of the indigenous population of the Americas died from disease after European contact.

234

If you lived in a village of 100 people, within a generation, only a handful of you would still be alive.

235

Smallpox killed more Native Americans than all of the European weapons combined by a landslide.

236

And some empires collapsed before the Europeans even showed up.

237

The Inca Emperor, Huayna Capec, he died of smallpox in 1527 without ever seeing a Spaniard.

238

The disease traveled faster than the conquistadors did, spreading through trade routes and wiping out populations before Europeans ever arrived to conquer them.

239

By the time Pizarro marched into Peru, the Inca empire was already in chaos.

240

A smallpox epidemic had killed the previous emperor and sparked a civil war over succession.

241

But why didn't it work the other way around?

242

Why didn't Native American diseases wipe out the Europeans?

243

Why was it a one-way street?

244

Europeans brought smallpox, measles, flu, typhus, plague, tuberculosis, and more.

245

The Europeans, the only thing they got from the natives was syphilis.

246

The exchange wasn't even close, and the answer goes back to those domesticated animals.

247

Those sheep, pigs, cows, and other animals, They weren't just food and labor, they were also disease factories.

248

Eurasians lived intimately with their domesticated animals for thousands of years.

249

They slept in the same structures, handled them daily, they breathed the same air.

250

And diseases often leap from animal to humans.

251

Smallpox jumped from cattle.

252

Flu morphed from diseases in pigs and ducks.

253

Measles came from cattle and sheep.

254

It goes on and on.

255

Native Americans had fewer domesticated animals and never lived in close quarters with them, so they never developed these diseases.

256

But animals alone weren't enough to create some killer epidemics.

257

You also needed something else.

258

Lots of people, like cities.

259

Diseases like measles, smallpox, and tuberculosis are what they call crowd diseases.

260

They need large, dense populations to survive and keep progressing.

261

Measles, for instance.

262

It needs at least 500,000 people to keep circulating.

263

And if the population is smaller than that, the disease burns through everyone, and then it dies out as well.

264

So hunter-gatherers, they didn't get those.

265

A band of 50 people moving through the forest, it's just not enough bodies for measles to survive.

266

But agriculture created the population density, and thousands of people packed together were the perfect breeding ground.

267

And the diseases were brutal over centuries and centuries.

268

They killed millions of people across Europe, Asia, and North Africa for thousands of years.

269

But here's the thing about epidemic diseases.

270

If you survive them once, you're often immune for life.

271

Your body develops antibodies, and sometimes those are passed down.

272

Over thousands of years, Eurasians developed genetic resistance, not complete immunity, but enough that the diseases were manageable.

273

The Americas didn't have any kind of protection like that.

274

So when the Europeans arrived with all of these invisible plagues, Native Americans had zero defenses.

275

The geographic lottery didn't just determine who had steels and guns, it determined germs as well.

276

And that turned out to be the deadliest weapon of all.

277

So I started asking why the Europeans had taken over the world, but that certainly doesn't mean it's going to last forever.

278

I mean, geography isn't destiny forever.

279

And the advantages have shifted.

280

Modern technology, it spreads globally in months, not thousands of years.

281

But understanding this history matters, and it explains the world we inherited.

282

It also helps explain why Africa is compared to the rest of the world now.

283

I mean, the world has given billions of dollars to the continent, and to many, it seems like the problems are still there.

284

And I ask a tough question.

285

Is it lost cause.

286

But as always, there's a twist to these things and it's a fascinating video.

287

I learned a lot from it.

288

I'm Ken LaCourt.

289

I did my best to give you these arguments straight.

290

It's a terrific book.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
