癌症究竟是怎麼發生的呢？跟著影片一起了解吧！（A New Way to Understand Cancer）
10:25
- Some mutate in a way that makes them weaker, others' mutations don't change anything, while a few become fitter and better at survival.
有些變異方式使它們變得更弱、其它的變異沒有改變什麼，而少數則變得更健康、更擅長生存。
- If more mutations happen, then some of the cancer cells will begin to explore the world and expand into other tissues to build new towns.
如果更多的變異發生，那一些癌細胞將開始探索世界並擴展到其它組織並建立新的城鎮。
該生小孩了嗎？ (When Should You Have A Baby?)
04:43
- And while men do continually make new sperm, the more cell divides the higher probability of genetic mutations.
不過雖然男性隨時都在製造新的精子細胞分裂次數越多，基因突變的機率也越高。
- the higher probability of genetic mutations.
細胞分裂次數越多，基因突變的機率也越高
恐龍變鳥、猴子變人：什麼是演化？(What is Evolution?)
08:53
- These mutations, which happen completely on accident and randomly to any part of a DNA strand, can produce variation in the body shape and function of the creature who inherits the modified DNA.
這些變異純屬意外且有可能發生在任一段 DNA，繼承了這些變異 DNA 的生物將可能在身形外觀或是生理機制上有改變。
- Besides the unique recombination of her parents' traits, she might also have developed some completely new traits of her own due to DNA mutations.
除了遺傳自爸媽的、那套重新組合的特徵，因著 DNA 變異，她或許也會發展出自己獨有的新特徵。
植物會得癌症嗎？ (Do Plants Get Cancer?)
02:18
- starts in humans or other animals because of mutations in a cell’s DNA that mess with the normal cellular growth cycle.
在人類或其他動物體內發生，因為細胞中的DNA搗亂正常的細胞生長週期。
1000年後的人類 (Humans In 1000 Years)
04:07
- New traits from mutations may also arise - perhaps a new eye color, or unique abilities! Even
從基因突變的新特徵也可能出現－可能是一種新的眼睛顏色，或是特殊能力
歷史之前發生了什麼？人類起源 (What Happened Before History? Human Origins)
10:06
- Before that, the babies would probably lack a few crucial gene mutations
在那之前，我們抓到的嬰兒可能會 少了幾個關鍵的基因突變
先有雞還是先有蛋？ (Which Came First - The Chicken or the Egg?)
03:31
- These small mutations in DNA over thousands of generations create new species.
這些 DNA 的小變化在數千代之後創造了新的品種。
- But these genetic mutations must occur in the zygote or initial cell, so a creature very similar to a chicken (which we could call a porto-chicken would have mated with another proto-chicken and because of a small genetic mutation created the first chicken, which grew in an egg.
但這些基因變化必須發生在受精卵或原始細胞，所以一個很接近雞的生物 (我們稱之為「原型雞」)，要與另一隻原型雞配對，同時因為微小的基因變化，而創造出第一隻雞，而它由蛋所生。
