Q
Q: What is convergent evolution?
A
A: The evolution of similar traits in unrelated lineages due to adaptation to similar environments or lifestyles.
2
Q
Q: Give an example of convergent evolution in dinosaurs.
A
A: The sail structure in Spinosaurus and Ouranosaurus evolved independently.
3
Q
Q: How can convergent evolution complicate phylogenetic analysis?
A
A: It can make unrelated species appear similar, obscuring true evolutionary relationships.
