Selection Factors
Selection factors are those environmental conditions / factors that affect the individuals and thus their fitness. A distinction is made between abiotic (inanimate) and biotic (living) selection factors.
The selection factors are crucial to the direction of evolution.
Biotic environmental factors: All selection factors that emanate from the living environment. These can be distinguished between intraspecific (intraspecific) and interspecific (extra-species) factors.
Intraspecific selection factors:
Sexual selection: selection of a sexual partner based on certain characteristics (for example songbird song, deer antler or peacock plumage, see also sexual dimorphism)
Interspecific selection factors: (Founded by hunter-prey relationship)
Imitation of the environment, for example by adapting color and shape (mime); Examples: walking leaves, living stones, chameleon
Imitation of another kind, e.g. protected by poisons. Thus, in the case of predators, the impression is given that the harmless animal is dangerous (mimicry); Example: The harmless hoverfly looks similar to the wasp, and is thus avoided by any predators
Summary
Biotic (alt. Bios = life) selection factors are based on the living environment
A distinction is made between intraspecific and extra-species selection factors
