1) a. Two different species that possess a homologous trait are a bat and a horse because they have similarities in their limbs. Both the horse and the bat look completely different, yet have similar structures that have evolved over time. b.  The bat and horse's homologous structure is compared through the batwing and the horse leg. The bat leg is thin and similar to a "hand like" structure. It has one long bone and then a few smaller bones. The function of the wing allows the bat to glide through the air and essentially travel. The Horse leg has a large femur or large bone that connects to the hip bone. Both the horse and bat have a long bone, a connector bone, and then a cluster of small bones. While they are the same structure, they both have different functions because the bat is made to fly while the horse is made to run or walk. c. A possible ancestor for these two animals is the Tiktaalik. This is because the Tiktaalik portrayed many similar traits in mammals t...

1. I believe that Alfred Russel Wallace had the greatest influence on Charles Darwin due to Wallace's theory of Natural selection. Wallace actually came up with the theory of natural selection. Darwin had many ideas that were contributed directly from Wallace in which he got to test while traveling around the world, especially to the Galapagos Island. 2. Alfred Russel Wallace contributed many theories including the study of species scattered around the world and how they were formed. He also, of course, contributed the ideas of natural selection which Charles Darwin later studied.  https://evolution.berkeley.edu/evolibrary/article/0_0_0/history_14 3. Wallace had the idea that "if the environment changes, the traits that are helpful or adaptive to that environment will be different." This is the idea or theory of natural selection that Wallace introduced in which animals can develop different traits depending on their environment. Darwin furthered with this theory in t...
