because Charles Darwin went and researched the animals on the galapogus islands, he has found out more and more stuff about evolution, variation, etc. since he did that research, he has helped scientists classify organisms into groups
Yes, it most certainly did. Since common descent became fact, biologists mostly classify organisms not by their place in the nested hierarchies, but by their descent. Although, interestingly, it was the first attempts to systematically classify life, by Carl Linnaeus, that provided the key insights leading eventually to the thesis of common descent, as formulated by Charles Darwin.
yes
Scientists who study evolution are called evolutionary biologists. They research the processes of genetic change and natural selection that drive the diversity of life on Earth.
Evolution.
evolution
To be strictly genetic; evolution is the change in allele frequency over time in a population of organisms. Loosely; evolution is change over time in living organisms.
Biologists base their belief in the theory of evolution on a wide range of scientific evidence, including fossil records, anatomical similarities among different species, genetic studies, and observations of natural selection in action. These pieces of evidence provide a comprehensive understanding of how species change over time and how different organisms are related through common ancestry.
No. Evolution explains how and why organisms change over time. It makes no difference to evolution how organisms are generated.
evolution
Evolution is change over time in a population of organisms. Formal and impressive to teacher definition is this; ' Evolution is the change in allele frequency over time in a population of organisms. '
Evolution is the change in allele frequency over time in a population of organisms.
No. This is a common misconception that natural selection will not eliminate the " weak " id we medically ameliorate their problems. This misconception is even held by some biologists. Actually, the coin evolution pays in is reproductive success and natural selection can be a creative force to that end. Evolution is the change in allele frequency over time in a population of organisms and the " stunted path " concept implies progress in evolution, but evolution does not care about progress, only reproductive success. If alleles change frequency in populations of organisms, which they do, evolution is not being " stunted, " whatever that means.
