人類為什麼要這樣演化？！ (Why Did Humans Evolve Like That? ?)
- The similarities between humans and great apes is what led many biologists, like Charles Darwin, to suspect that you share a common ancestor and to investigate where your genetic differences originated.
人類和類人猿之間的相似性促使許多生物學家，如查爾斯-達爾文，懷疑你們有一個共同的祖先，並研究你們的基因差異起源於何處。

恐龍變鳥、猴子變人：什麼是演化？(What is Evolution?)
- A massive amount of observable evidence from many different fields such as genetics, chemistry, paleontology, and mathematics, overwhelmingly suggest that just like all dogs share common ancestor, all living things, me, you, puffer fish, banana trees, if you go back far enough, also share a common ancestor.
來自遺傳學、化學、古生物學及數學的大量證據壓倒性地指出：所有的生物，你、我、河豚、香蕉樹，皆源自同一位古老祖先。

我們該不會全部都是親戚吧？ (Are We All Related?)
- If we replace that with fancy math, factoring in how people moved and lived and paired up life expectancy, trade, geography, Genghis Khan, we find something interesting: every human alive today shares a common ancestor in their family tree,
那麼那些遺失的祖先去哪了呢？
