Evidence for Evolution
Problems
Problem : The wings of birds and insects are considered what kind of structures?
Problem : How can embryology help in the study of evolutionary relationships?
Problem : A naturalist cataloging species in a remote forest discovers two different varieties of beetles. Both have a large horn-like structure on their heads that they use to dig into the ground to find food, but they are otherwise not very similar. What conclusions can the naturalist draw from this comparison of traits?
