Question

what does comparative anatomy study among different species?
a. behavioral adaptations
b. genetic similarities
c. fossilization processes
d. anatomical structures
what do vestigial structures indicate about an organisms evolutionary history?
a. they are adaptations that enhance an organisms survival.
b. they are fully functional organs that have adapted to new roles.
c. they are remnants of organs that have lost their original function.
d. they are structures that have evolved independently in different species.
what is the primary evidence for the theory of continental drift impacting species distribution?
a. fossil records
b. genetic mutations
c. similar species found on different continents
d. anatomical structures

Explanation:

Comparative anatomy focuses on comparing anatomical structures among different species. Vestigial structures are remnants of organs that once had a function but have lost it over time in the course of evolution. The presence of similar species on different continents is a key piece of evidence for the theory of continental - drift affecting species distribution as it suggests that these species were once in the same location before the continents drifted apart.

Answer:

1. d. Anatomical structures
2. c. They are remnants of organs that have lost their original function.
3. c. Similar species found on different continents
