A whale’s flipper has a very similar anatomical structure to a bat’s wing. They each have a large bone in the upper arm, two bones in the lower part of the arm, and a smaller collection of bones creating a sort of wrist with fingers. Even those these two species are so different, they clearly must come from a similar ancestor and have evolved in different directions from this.
All species store information by use of DNA. Humans and roundworms share about 25% of their genes. In some situations, genetic material can be transferred between species and will continue to function, …show more content…
The unborn baby remains hairy for weeks of development. This layer will not shed until just before, or soon after birth. Only the hair on our head, eyebrows, and eyelashes remain. This most comes from the non-human primates we evolved from.
When factories were creating pollution that changed the colors of the bark on birch trees from white to gray, the color of the moths become a large factor in survival. The moths who were gray could blend in with the new color, hiding from predators. The white moths had a harder time. This caused there to be a higher concentration of gray moths to survive and, therefore, reproduce. With the higher frequency of grey moths reproducing with this allele, the species would evolve to maintain this allele for better survival in the environment.
Breeders select dog with desired characteristics to ensure that those characteristics made it to the next generation. If a breeder wants a dog with a curly coat, they would breed only dogs with this same trait. This has created numerous breeds of dogs so that the original ancestor of dogs has evolved into so many
