Let's solve this question here.
00:02
The question is about the homologous structures, homologous structures, and vestigial structures, vestigial structures.
00:19
So here they are saying that how these two that is homologous structure and vestigial structure.
00:25
They are the evidence of evolutionary relationships, evolutionary relationships.
00:35
So here first of all, let's understand that what is homologous structure.
00:40
These are actually homologous structure.
00:42
These are the anatomical features, anatomical features.
00:50
Here the word we are using is anatomical.
00:53
So this is the anatomical features.
00:55
This is found in different species that share a common ancestral origin.
01:03
For example, here it can be understood as the forelimbs, forelimbs.
01:10
So this is present in vertebrates such as we human beings are there, bed, dog, means animals are there.
01:20
And so these are what these are the forelimbs of these are the homologous structure.
01:26
Now what is vestigial structure then? so these are the remnants, remnants of anatomical features, remnants of anatomical features.
01:42
And here they are functional in ancestors, but they have now lost their origin function...
