You and your friend inspect a group of fossils from different organisms with various features. Your friend is convinced that all of the fossils are unrelated, but you find evidence that these organisms share an ancestor. What is an example of evidence that you could use to best support this argument?

Question

a
heights
b
patterns in limb structures
c
tooth features
d
number of bones

Answer 1

B) Patterns in limb structures could be used as evidence to support the argument that these organisms share an ancestor. Similarities in limb structures indicate common ancestry, as bones and joints are often adapted over time to suit specific functions, such as walking, running, or gripping. By observing similarities in limb structures among the group of fossils, one could infer that these organisms may have evolved from a common ancestor.
