1
This is you, and these are your two parents.
2
They each have two parents as well, who are your four grandparents, who each have two more parents.
3
With every generation, the tree grows, meaning by the time you go back to the year 1400, you'll have over 16 million ancestors.
4
And if you go back a few centuries more, your family tree will include more humans than the population of Earth at that time.
5
But that's because the further back you go, the less people there were on Earth.
6
So the more likely it is your ancestors were already related, with distant cousins marrying each other.
7
And that means one ancestor will show up more than once in different places on your family tree.
8
Meaning it's not that big after all.

シャドーイングとは?英語上達に効果的な理由
シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
