Analogous

Answer 1

Homologous structures share a common ancestry, whereas analogous structures have similar functions but evolved independently.

Step-by-step explanation:

To categorize the structures as homologous or analogous, we need to understand the difference between them. Homologous structures are anatomical features that have a common evolutionary origin but may serve different functions, while analogous structures have similar functions but evolved independently and do not share a common ancestry.

1. The mammalian tail and the human coccyx (tail bone) are homologous structures, as they both derive from the same embryonic structure, even though their functions may differ.
2. The leaves of pitcher plants and cacti are analogous structures because they have different origins and perform similar functions of capturing and digesting prey.
3. The flippers of penguins and dolphins are analogous structures, as they have similar functions and evolved separately in response to the aquatic environment.
4. The bills of ducks and platypuses are analogous structures since they have different origins but serve similar functions, like capturing food.
5. The shells of turtles and crabs are analogous structures because they have different evolutionary origins but provide protection for the organisms.
