00:00:00,120 --> 00:00:02,910
내 이름은 Bill Durham입니다. 나는 Bing의

2
00:00:02,910 --> 00:00:07,080
인간 생물학 교수이자 스탠포드 대학의 인간 생물학과 인류학 교수입니다.

3
00:00:07,080 --> 00:00:11,710
음, 우리는 당신이 우리와 함께하게 되어서, 특히 매우 중요한 개념에 대해

4
00:00:11,710 --> 00:00:13,770
얘기할 수 있어서 정말 기쁩니다. 지금 우리는

5
00:00:13,770 --> 00:00:16,680
유당 불내증과 모든 유아를 예로 든 지식에 대해

6
00:00:16,680 --> 00:00:20,580
지금 막 알아냈습니다. 우리는 포유동물과 같이 생성물을 포함하고 있는

7
00:00:20,580 --> 00:00:23,420
젖당을 소화하기 위한 능력을 갖고 있습니다. 그리고

8
00:00:23,420 --> 00:00:26,280
우리가 늙어감에 따라, 우리의 젖당 분해 효소 유전자 단백질 합성은 줄어듭니다.

9
00:00:26,280 --> 00:00:29,350
하지만, 몇 사람들에 한해서, 젖당 분해 효소 유전자 종류가 계속 남아있습니다.

10
00:00:29,350 --> 00:00:31,780
그리고 우리는 젖당 분해 효소를 계속해서 만들어냅니다. 그래서 전

11
00:00:31,780 --> 00:00:35,060
우리는 왜 인간 진화에 이런 일이 일어났는지를 물어보면서

12
00:00:35,060 --> 00:00:38,270
시작할 것이라 추측합니다. 어떻게 이런 일이 일어날 수 있는건가요?

13
00:00:38,270 --> 00:00:42,350
음 그러니까 출생 때쯤이면 젖당 분해 효소의 활동이포유류 이동 배경으로부터

14
00:00:42,350 --> 00:00:45,790
절정에 치닫고 그 후 재빨리 이유(離乳)하는 기간과 성인으로 접어들게 되는

15
00:00:45,790 --> 00:00:48,360
성인으로 접어들게 되는 곳인 포유류 이동 배경으로부터

16
00:00:48,360 --> 00:00:51,630
우리는 그런 모습을 띠게 되고 우리는 그 모습에서 포유류라는 것을 안다.

17
00:00:51,630 --> 00:00:54,840
심지어 당신의 애완 고양이도

18
00:00:54,840 --> 00:00:58,880


19
00:00:58,880 --> 00:01:01,920


20
00:01:01,920 --> 00:01:05,200


21
00:01:05,200 --> 00:01:07,080

00:01:07,080 --> 00:01:09,390
