Bird. You can see that first contact with the ground is not at the wrist but the end of the palm of the hand where it joins with the fingers. Homologous structures occur in organisms that are derived from a common ancestor, while analogous structures do not. Scientists say these similarities are evidence that life on earth shares a common ancient ancestor from which many or all other species have evolved over time. sensitivity to motion/vibration/electrical impulses/sound/smell/taste, show individual variations on a common anatomical theme.

Structures in adult lobsters and crayfish are so similar (homologous) that the same lab instructions can be used for dissecting either, yet the crayfish egg develops directly into the adult form while the lobster egg reaches the homologous pattern through a free-swimming larval stage. Q:Make a comparison between vertebrate and non vertebrate. This is why analogous structures are sometimes used as evidence for convergent evolution. Explanation: The difference between the human hand and that of the cat are uses of the appendage and the size and number of certain bones.
