could individuals of a species look different today

What is the reason for the phenotypic differences between individuals of the same species? Do species evolve at a faster rate if they have a larger population due to being more likely to experience genetic mutation? What does this tell Scientists about Earth's past? It takes a long time for an individual to adapt to its environment. For example, if one individual of a species had a mutation that caused them to have red eyes, while the other individuals of the species had the normal allele for eye color, the individual with the mutation would stand out. _______ among populations can keep them similar to one another.

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. The descendants would look different from the original individuals in some ways, and they would look the same in some ways. It's very important, and theoretically you could have a race where everyone has the same genotype for physical appearance.

B. organisms change by acquired characteristics. Bio diversity refers to every living thing, including plants, bacteria, animals, and humans. Does the question reference wrong data/reportor numbers? This observation led her to hypothesize that longer horns offer more protection against predation than do shorter horns. This is a question that has been debated for many years. The birds' beaks varied in size, with some individuals having slightly smaller beaks and others having slightly larger beaks. They can help us get to the root of how biological diversity has evolved. Campagna and collaborators were the first to show that this finch radiation is relatively recent and still ongoing. For example, a shark uses its electrosensory and olfactory organs predominately to interact with its environment, whereas primates are heavily dependent upon vision. By the year 2000, the graph shows the population of light colored moths significantly increasing. Explain. not?
