Question

5. The diagrams below show the bones in the forelimbs of three different

organisms. Which hypothesis do the differences in the bone
arrangements support?
Human
Whale
Bat
These organisms are members of the same species
These organism have adaptations to survive in different environments
These organisms evolved at the same time
These organisms all contain the same genetic information

Answer 1

The forelimb of human, whale and bat have a common fundamental anatomical plan and similar embryonic origin (one large upper arm bone, two small lower bones, carpals and metacarpals). The main difference of the forelimb of this 3 mentioned is in their various function

Step-by-step explanation:

he forelimb of human, whale and bat have a common fundamental anatomical plan and similar embryonic origin but with varied functions. They have the larger upper arm bone as the humerus, while the 2 smaller lower bones are ulnar and radius and the carpals and metacarpals in the wrist and hand. The human fore limb function in grasping, whale uses it forelimb (flippers) in swimming while bat uses theirs in flying.
