How is it the same? The three conditions that must be met for evolution to occur by natural selection are that there must be variation, there must be selection, and there must be inheritance of variation. In what ways is the human brain different from other species (non-primate and non-human primate)? why or why not? Why or why not? All of the following are protective adaptations except one. A species is a population of plants or animals that can breed to produce offspring that can then produce offspring themselves. The smallest and largest snails would be the most likely to reproduce. Explain how the mechanisms of evolution, such as natural selection, would be at play in the changing of human genes. (I am of the assumption that changes in DNA spur the adaptations that take place--at least those through genetic mutation--and thus the adaptations, In what way is artificial selection different from natural selection? Could individuals of a species look different today chegg? Recently, more and more farmers have discovered that their fields have Roundup-resistant pigweed growing along with their crop.

Experts are tested by Chegg as specialists in their subject area. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Yet why do some races seem to have darker (or lighter) skin tones than others? The mosquito population needed to evolve DDT resistance in order to avoid extinction. By what mechanisms have we evolved into distinct species? Will evolution occur if there is no variation in a population, if the only variation is acquired and not inherited or if all progeny survive and equally reproduce? 2. 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.
