The main purpose of biological taxonomy is to use a systematic method to name,
organize, and show relationships among species.
Taxonomy<span> (from
Ancient Greek: τάξις taxis, "arrangement", and -νομία -nomia,
"method") is the science of defining groups of biological<span> organisms on the basis of shared characteristics
and giving names to those groups.</span></span>

2. Darwin also named some factors that affect the process of natural selection. Among these were overproduction, competition, and variations. Overproduction happens when species reproduce many more offspring than can possibly survive. ... Those who are better able to survive then pass on their genes to their offspring.
3. Evolutionary change can occur through mutation and natural selection. Mutations are genetic changes in an organism. ... Even though outside factors can cause mutation to occur, what kind of genetic change will occur is random. Mutations can be harmful, beneficial, or neutral.

Adrenal glands are responsible of cortisol.Cortisol<span> has many functions but gigantism is not one of it.

Ecological succession , or the process in which the structure of a community evolves over time, means that the species composition, density, and distribution of that community is constantly changing as time progresses. A community may eventually reach its climax, the point where the composition remains mostly stable unless some sort of disturbance occurs. Otherwise, communities are constantly changing.
