A species’ life history describes the series of events over its lifetime, such as how resources are allocated for growth, maintenance, and reproduction. Life history traits affect the life table of an organism. A species’ life history is genetically determined and shaped by the environment and natural selection.
16 Σεπ 2024 · Natural selection is said to be a major driving force of evolution. Evolution can be defined as the change in the frequency of a phenotype in a population over many generations. Darwin’s theory, very simply, is: Individuals in a species compete for limited resources. The population shows a wide range of variation caused by differences in genes
