Take your time to answer i'll be (98 points) ~biology~ suppose that you found a vertebrate fossil and brought it to an expert. the expert showed you that the joint structure of the fossil was similar to the joint structure of a modern squirrel. infer the kinds of movements for which the animal had been adapted. explain your inferences in a paragraph.

As we know before in back in time. Animals will adapt to their environment that their ancestors didn't have. This animal must have used to have a straight legs but then adapted since it couldn't really move. Then over time it most have started to bend so that way it could move faster. I think that it must have had straight legs because most animals aren't originally the same like humans have tailbones and tails or six fingers. I also feel that it was a analogous structure. Because the squirrel and vertebrate fossil had the similar appearance but are not evolved together and don't have a common ancestor.

(Hope this helps!)

trachea, alveoli, lung capillaries, arteries

fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
