Question

How do the 'homologous characteristics in different organisms help to
identify the evolutionary relationships?​

Answer 1

Answer:

Similar traits can be either homologous or analogous. Homologous traits share an evolutionary path that led to the development of that trait, and analogous traits do not. ... Phylogenies based on molecular characters assume that the more similar the sequences are in two organisms, the more closely related they are.

Answer 2

For example, reptiles and mammals. All of them have 4 limbs. The basic structure of their organs is more or less the same, although they utilize it for varied functions. These organs are known as homologous organs. This does not mean that they share the same ancestor.

thus, homologous characteristics help in tracking an evolutionary relationship between different species.
