To prove that having two eyes is an adaptive trait, for instance, one first has to use geometry to show that stereoscopic vision enables depth perception.
22.
One perspective is that traits are only adaptive traits if they lead to a persistent population, i . e . the species / strain doesn't go extinct.
23.
;Speciation : It has been suggested that many polyploidization events created new species, via a gain of adaptive traits, or by sexual incompatibility with their diploid counterparts.
24.
It is unknown exactly how this adaptive trait developed in fungi, but it is clear that the relationship to the plant forced the development of the process.
25.
He describes frozen plasticity as being more general, and maintains that it better explains the origin of adaptive traits in genetically heterogeneous populations of sexual reproducing organisms.
26.
"Objection " : Evolutionary biology can be fallacious when it proceeds by breaking an organism into adaptive traits and proposing an adaptive story for each trait considered separately.
27.
On the other hand, some adaptive traits and the population differences are driven by positive selections of advantageous variants, and these genetic mutations are functionally relevant to population specific phenotypes.
28.
Stochastic events initiated the appearance of features that we might view as adaptive traits, and it is the local evolution of these traits that much of evolutionary theory is based upon.
29.
Unlike melanistic wolves and coyotes, which historically received their dark pigmentation from interbreeding with domestic dogs, melanism in golden jackals likely stems from an independent mutation, and could be an adaptive trait.
30.
:A more well-formed question is " is human skin color an adaptive trait ? " It might be, but it might be a talk ) 04 : 06, 23 March 2013 ( UTC)
