Question

Why does evolution not produce global fitness maxima but rather local adaptive peaks? How does this relate to exaptation? Discuss. Illustrate your answer with examples.

please provide a clear detailed answer that is easy to read. thank you

Answer 1

Ano: To understand the evolution fitness cohen maaina by a with global graph peach (P » global Fitown global fitness Lhen pl Реал» » fitness neith multiple peako When the the environment change there is a nos of species formed who competing with the changes for the new evolutions. In the adaptive topography population also changes. In this conditions shap, size, land also change, so the mutation also changes. Because mutation depends upon the adaptative environment A new allele may interact with other allele that existing in the environment. On that base fitness of the allele also changes. So the genetic condition also change during evolusons- for the new mutant. So the manimumtime natural selection is in hill-climbing procen. Population. go upward direction when the serface is change. In the time of natural selection procen hill climbing process, means maximum global fitnen in localised. And the global fitnen is. opposite of local fitron. local titsen of peach, select the retaria where mutation cangrow but in the

global fitness on peak (globas coness namber of area with surface changes and covers numbers of changes in different species with the evolutions How it related to exaptation @xaptabon → It called as co-option which explain the function of speciality during the evolution. Co-option means like a specific function of particular function but can serve another functionalso. During evelution, Ascientist named Charles Darwin» she saw evolution had Sifted several times (means adapted and numbers of function during time changing) exaptation is related with adaptation For example - Feather evolved for heat regulation. but at time feather rask for flying. another example lungs of many basal fist. evolved for terrestial vertebrates but when go under crater work as a gas bladder. mother example Regarding Arthropoda are earliest fossils of land animal of the terrestrial animal. They well pre adaptine to colonine land. They have existing joints that provides suppoot against the granity and other mechanical support of components that could interact to provide lever, columna and other means of locomotion al so the exaptation is related to evolution, because when adaptation evolved then then the exaptation also work their summary : - global peak related to the numbers of adaptation according to the surface, landand environment changer and exaptation evolved their or
