Question 1 1 / 1 point
Match the idea or concept about how species came to be what they are today with the person who came up with that idea or concept:
__4__ He believed that organisms change in response to environmental conditions, and that these changes could be inherited. This is different from our current understanding of evolution and genetic inheritance where organisms do not pass on traits that are newly acquired over their lifetimes.
__3__ This person came up with the theory of "natural selection" which is a similar process to artificial selection whereby some traits become more common in a population over generations of time, whereby others become less common. But instead of humans controlling which traits become more of less common, nature decides based on which individuals are best able to survive and reproduce in their environment. Over time (generations) this can lead to the formation of new species.
__1__ Life forms cannot change, but can be organized by differences in similarities. This person came up with the two more classification categories in addition to genus and species: class and order. He was the first to place humans in the animal kingdom.
__2__ This person sent Charles Darwin a copy of his theory which was essentially the same as Darwin's theory of natural selection, proposing that new species are descendants of older species which have changed in response to environmental pressures.
