Populations of organisms change over time
WebEvolution is the change in inherited characteristics or traits in a population of organisms over many generations. The mechanism that best explains evolution is a phenomenon known as natural selection. Natural selection is the process by which certain inherited traits—such as the color of a fish, height of a person, or shape of a leaf—are favored within … WebSep 23, 2011 · The bees collect far more of their “cologne” from other sources, such as tree resin, fungi and leaves.

Web1 answer. Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. By studying the frequency of genes like HMGA2 in Darwin's finches, scientists can observe how natural selection acts on these genes in response to changes in the environment. This demonstrates evidence of natural ... WebMost changes in ecosystems and their services are gradual and incremental, making them, at least in principle, detectable and predictable. However, many examples exist of non-linear and sometimes abrupt changes in ecosystems. A change may be gradual until a particular pressure on the ecosystem reaches a threshold, at which point rapid shifts to ...
