Any structure, physiological process or pattern of behavior that increases genetic value. 2. The process by which natural selection produces changes that increase genetic value.

What is evolutionary fitness measured by?

The central concept of natural selection is that an organism's evolutionary fitness is measured by one organism's ability to survive and reproduce, which determines the magnitude of its genetic contribution to the next. it is determined by the proportion of subsequent generations that carry the genes of the organism.

What does natural selection cause

Natural selection can lead to speciation, where one species gives rise to an entirely new and different species. This is one of the processes that drives evolution and helps explain the diversity of life on Earth. Darwin chose the name "natural selection" rather than "artificial selection" or human-controlled selective breeding.
