Give significance of Natural selection?
Answers
Answer:
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Explanation:
The Process of Natural Selection
Darwin’s process of natural selection has four components.
1. Variation: Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring. On the other hand, some traits show little to no variation among individuals—for example, number of eyes in vertebrates.
Inheritance: Some traits are consistently passed on from parent to offspring. Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.
High rate of population growth: Most populations have more offspring each year than local resources can support leading to a struggle for resources. Each generation experiences substantial mortality.
Differential survival and reproduction: Individuals possessing traits well suited for the struggle for local resources will contribute more offspring to the next generation.
