2
00:00:09,629 --> 00:00:07,680
the astrobiology program is pleased to

3
00:00:11,749 --> 00:00:09,639
welcome the life early cells to

4
00:00:14,870 --> 00:00:11,759
multicellularity research coordination

5
00:00:17,750 --> 00:00:14,880
network to our astrobiology rcns the

6
00:00:21,109 --> 00:00:17,760
overarching set of questions

7
00:00:23,990 --> 00:00:21,119
uh in our rcn is how why and when did

8
00:00:26,950 --> 00:00:24,000
life and the environment co-evolve

9
00:00:29,509 --> 00:00:26,960
to take earth from a number of major

10
00:00:30,790 --> 00:00:29,519
changes both in its geology and its

11
00:00:32,470 --> 00:00:30,800
biology

12
00:00:34,549 --> 00:00:32,480
so we want to look for life on other

13
00:00:36,229 --> 00:00:34,559
worlds but but what are we looking for

14
00:00:38,389 --> 00:00:36,239
and the problem is that we don't really

15
00:00:40,869 --> 00:00:38,399
know the rules that govern the evolution

16
00:00:41,910 --> 00:00:40,879
of life on different sorts of planets so

17
00:00:43,910 --> 00:00:41,920
how does how does life evolve

18
00:00:45,430 --> 00:00:43,920
differently if the planet's environment

19
00:00:47,110 --> 00:00:45,440
if it's chemistry if the abundance of

20
00:00:48,630 --> 00:00:47,120
the economic elements are different than

21
00:00:50,310 --> 00:00:48,640
they are on earth we just don't know and

22
00:00:52,630 --> 00:00:50,320
earth is our natural lab for figuring

23
00:00:55,110 --> 00:00:52,640
that out why is studying early life

24
00:00:57,270 --> 00:00:55,120
interesting to us astrobiologists and

25
00:00:59,430 --> 00:00:57,280
nasa key events in the earliest

26
00:01:02,310 --> 00:00:59,440
evolution of life seem to be truly

27
00:01:05,109 --> 00:01:02,320
singular they happened only once and

28
00:01:07,750 --> 00:01:05,119
never before or since has anything

29
00:01:09,750 --> 00:01:07,760
comparable happened again history of

30
00:01:12,630 --> 00:01:09,760
life and early innovations are almost

31
00:01:15,350 --> 00:01:12,640
begging for us to study them we need to

32
00:01:17,990 --> 00:01:15,360
study these biological singularities to

33
00:01:21,190 --> 00:01:18,000
have any hope of estimating or locating

34
00:01:22,710 --> 00:01:21,200
complex life in the universe so rrcn

35
00:01:25,030 --> 00:01:22,720
life from early cells to

36
00:01:27,270 --> 00:01:25,040
multicellularity will focus on the

37
00:01:28,630 --> 00:01:27,280
co-evolution of life and its planetary

38
00:01:31,190 --> 00:01:28,640
environment

39
00:01:33,109 --> 00:01:31,200
this rcn will advance our understanding

40
00:01:35,670 --> 00:01:33,119
of the causes and consequences of

41
00:01:37,030 --> 00:01:35,680
co-evolution recorded in a variety of

42
00:01:38,950 --> 00:01:37,040
types of data

43
00:01:41,350 --> 00:01:38,960
so we really hope that you will join

44
00:01:43,350 --> 00:01:41,360
this diverse group of astrobiologists

45
00:01:45,429 --> 00:01:43,360
whose research interests focus on the

46
00:01:47,030 --> 00:01:45,439
co-evolution of earth and life from

47
00:01:49,270 --> 00:01:47,040
earliest cells to the rise of

48
00:01:51,670 --> 00:01:49,280
multicellularity but also including

49
00:01:53,749 --> 00:01:51,680
prospects for advancing this science and
