Multiple Choice

How do Hox genes provide evidence for evolution?

They mutate rapidly, leading to completely different gene sequences in each species.

They are highly conserved across diverse animal species, indicating a common evolutionary origin.

They are unique to humans and absent in other organisms.

They only control metabolic pathways, not body plan development.

Verified step by step guidance

Understand what Hox genes are: they are a group of related genes that control the body plan of an embryo along the head-tail axis.

Recognize that Hox genes are highly conserved, meaning their sequences and functions are very similar across a wide range of animal species.

Analyze how this conservation suggests that these genes were present in a common ancestor and have been maintained through evolution due to their crucial role in development.

Compare the presence and function of Hox genes in different species to see how variations in these genes can lead to differences in body plans, supporting the idea of evolutionary divergence.

Conclude that the similarity and conservation of Hox genes across diverse species provide strong molecular evidence for common descent and evolutionary relationships.
