Does natural selection produce a change in individuals or populations?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
How does natural selection operate as a mechanism of evolutionary change?
-The mechanism that produces the change is natural selection: the differential survival and reproduction of individuals based on variation in their traits. Natural selection acts on individuals but individuals do not evolve; their descendants do.
Is natural selection a mechanism of evolution?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
How is natural selection an example of evolution?
Environments change over time, and natural selection acts on the genetic diversity in species. After many generations in this new environment, the current population may not look like their ancestors because natural selection has changed them – they have evolved – to survive in the new environment.
How is biogeography used as evidence for evolution?
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
Did Darwin discover evolution?
In the immediate aftermath, they both became famous. But after Darwin published his book On the origin of species by means of natural selection in 1859, he became known as the man who discovered evolution.
Who actually discovered evolution?
