Question

two organisms are very similar and share a common ancestor. however, they are distinct species. what type of evolution is this?
○ convergent evolution
○ divergent evolution
question 10 10 pts
scientists tracking fossils of extinct dinosaurs look to find the origin of each particular species of dinosaur. what are the scientists studying?
○ anatomical
○ embryology
○ biogeography
○ molecular evidence

Explanation:

For the first question: Convergent evolution produces similar traits in unrelated organisms, while divergent evolution occurs when closely related organisms (sharing a common ancestor) evolve into distinct species.
For Question 10: Anatomical study focuses on physical structures (fossils show skeletal/anatomical features of dinosaurs), embryology studies early development, biogeography focuses on species distribution, and molecular evidence uses genetic material (not available from most dinosaur fossils).

Answer:

1. Divergent Evolution
2. Anatomical
