Hello students, in this question we are being given the names of certain organisms and we have to create the evolutionary tree based on their relationship.
00:16
This is the group of organisms for which we have to make an evolutionary tree.
00:22
And we have to draw a simple tree going from the common ancestor to the species of interest which is the humans.
00:28
And mention what kind of trait we consider to separate each branch.
00:35
So this is the required evolutionary tree of group of organisms having a common ancestor.
00:44
And the first classification would be invertebrates which is lobster and vertebrates which is lizard, fish, birds and humans.
00:54
And further we will classify again these vertebrates into warm -blooded and cold -blooded.
01:01
Cold -blooded will belong to lizard and fish while warm -blooded will be humans and birds.
01:08
And further we will classify here on the basis of presence of hair and feather.
01:14
As we know the hairs are present in humans, feathers are present in birds.
01:19
And the most closely related among these organisms to humans is the birds.
01:27
In another question we are being asked to choose one animal and classify to the classification of that animal.
01:34
Animal i will be choosing is the bengal tiger and the classification would be like kingdom...
