Question 7

What is the difference between homologous evolution and analogous evolution?

Accepted Answer

A)  With homologous evolution, changes in a trait happen over one or two generations; with analogous evolution, changes in a trait occur over millions of years. 
B)  With homologous evolution, these are changes that occurred in single-celled organisms; with analogous evolution, these are changes that occurred in multi-cellular organisms.
