This question is looking at some characteristics of adaptive radiation.
00:08
So let's just review what that means first.
00:14
So adaptive radiation is where we have lineages that rapidly diversify.
00:26
Okay.
00:27
So we have lineages that rapidly diversified.
00:49
So it went from maybe a single species to a handful of them.
00:53
So those newly formed species evolve different adaptations that start to separate them.
01:03
So they have different adaptations.
01:18
And there can be different triggers for these.
01:24
They evolve different adaptations many times because they have different niches or habitats that expand to.
02:01
So if we look at a problem, we're talking about they want to see large scale worldwide adaptive radiation.
02:21
Okay.
02:22
So we're just talking about many different areas having a diversification scene in many different groups or many different species that started to diet.
02:35
Diversify.
02:36
So we have to think about that when we're looking at our problem.
02:42
So if we go through some of the characteristics or options for our answers, the first one that we can eliminate is a, where they have no available niches.
02:55
So a says no available niches...
