Hi.
00:03
So we have here the given question, which of the following are necessary for speciation to occur? now, speciation, this is the process by which populations evolve to become distinct species, and it involves the splitting of a single evolutionary lineage into two or more genetically independent ones.
00:26
Now, let's evaluate given options we have co -evolution.
00:32
Now, co -evolution, this is the process we're into or more species reciprocally affect each other's evolution.
00:41
Now, while it plays a role in speciation, this is not necessary for speciation to happen.
00:48
So not a condition.
00:58
We have co -evolution.
01:04
Second option, we have genetic divergence.
01:07
Now, genetic divergence plays a crucial role in speciation.
01:11
This refers to the process in which two or more populations of an ancestral species accumulate independent genetic changes through time, often after the populations have become reproductively isolated for some period of time...
