Which of the following best explains the presence of homologous genes in different species?
A) the species descended from a common ancestor
B) the homology developed due to convergent evolution
C) chance mutations were acted on by regional environmental selective pressures
D) analogous structures require proteins encoded by homologous genes

Question

Quizplus · Accepted Answer

Homologous genes in different species suggest that these species share a common ancestor from which they inherited these genes. This is a fundamental concept in evolutionary biology, indicating that similarities in genetic sequences are due to descent from a common ancestor, rather than convergent evolution, chance mutations, or the necessity of analogous structures.
