Question
Chapter 25, Problem 25.100P
Interpretation Introduction
Interpretation:
Interpret the reason of interbreeding between species of human.
Concept Introduction:
The extinction and non extinction of species depends on the character or traits present in the present organisms. These traits appear due to the presence of DNA present in species got extinct such as dinosaurs disappear though its character are still present in class of reptilia.
