Which of these is not part of darwin's idea of natural selection? a, heritable traits that promote successful reproduction should become more common.
00:10
B, organisms compete for limited resources.
00:13
C, populations produce more offspring than their environment can support.
00:17
Or d, whether an organism survives and reproduces or dies early and does not reproduce is almost entirely a matter of random so correct answer here is d.
00:27
It's not random chance.
00:29
That's part of natural selection, but it's not random.
00:32
So darwin saw that first of all, there are more offspring can be supported.
00:40
So more offspring than can be supported.
00:44
And this leads to competition over the limited resources.
00:48
So c leads to b.
00:52
So there's not enough food for all of them, they have to compete.
00:58
And this this competition means that as long as there is variation among the individuals, some are going to be better than others at getting the resources...
