state how evolutionary relationships can be traced by the study of homologous otgans
Answers
Homologous organs provides evidences for evolution by telling us that they are derived from same ancestor.
Answer :-
First of all, what are homologous organs?
Ans - Homologous organs can be defined as the organs which have similar structural appearance but have different functions.
Tracing evolutionary relationships can surely be considered as a method for conducting studies of homologous organs.
This can be well understood by the following example :-
The forelimbs humans and birds are homologous organs.
They have the same structural appearance and developmental origin but they have different functions.
Note :-
Homologous organs help us to understand that the organism which is being observed, has developed from the common ancestor.
The more common characteristics the two species have, the more closely they are related to each other.
