A researcher observed that lizards living in areas with predatory birds have longer horns than those in areas with no predatory birds. It was very effective at first, but after a few decades DDT became less effective at killing mosquitoes because many populations had evolved resistance to DDT. Why do humans try to save and treat every human life while other creatures are selected by natural selection? To test this hypothesis, the researcher tagged 20 lizards with long horns and 20 lizards with short horns in each of two locations: Desert Valley, where there are no predatory birds, and Cactus Corner, where there are predatory birds. These include the amount of genetic variation within a population, the number of evolutionary opportunities that a population has, and the number of genetic mutations that occur within a population.

Yes, some individuals with certain traits are more likely to survive and pass Are there such height differences in the animal kingdom? Similarities at the beginning of embryonic development imply they have common ancestors. Evolution refers to a process in which the genetic composition of a species changes over time, from one generation to the next. Variation allows some individuals to do better than others, so those variations are selected.
