Genetic changes in populations that are brought about by horizontal gene transfer in bacteria are an example of what means of evolution? How to choose between a treadmill and stationary bike. Monkeys that share a common ancestor may have different adaptations in different areas, while other traits reveal their common descent. One example of this process is the similar anatomical features shared between a dolphin and a shark. You'll find them used as earrings, necklace pendants, or even wallet adornments. exchange of genetic information in bacteria Colorful male guppies are more attractive to females and therefore are able to mate more often, leaving behind more offspring.
