Evolution is an observable phenomenon in which gene frequencies change over time, but it does not explain why a population is undergoing evolution. This is where natural selection—and other mechanisms—come into play. They explain “the why.” Natural Selection.
Adaptation raises philosophical issues concerning how biologists speak of function and purpose, as this carries implications of evolutionary history – that a feature evolved by natural selection for a specific reason – and potentially of supernatural intervention – that features and organisms exist because of a deity's conscious intentions.
2 days ago · Over the past 3 million years, humans have expanded their ecological niche and adapted to more diverse environments. The temporal evolution and underlying drivers behind this niche expansion remain...
2 days ago · Abstract. Organisms that are adapting to long term environmental change almost always deal with mul- tiple environments and trade-offs that affect their optimal phenotypic strategy. Here we combine the idea of repeated variation or heterogeneity, like seasonal shifts, with long-term directional dy- namics.
6 days ago · Cultural evolution refers to the gradual development and transformation of a society’s beliefs, customs, practices, and artifacts over time. Adaptation, in the context of cultural evolution, involves the ways in which a culture adjusts to its environment, internal changes, or external influences.
The authors argue that a consideration of developmental phenomena is needed for evolutionary biologists to generate better explanations for adaptation and biodiversity. This book provides a new vision of adaptive evolution.
In summary, our study provides insights into the molecular and evolutionary mechanisms underlying the adaptation of A. disparis to extreme aggression and provides a valuable genomic resource for further research into the molecular basis of trait evolution in insects.
Adaptation is a specific aspect of evolution, focusing on the adjustments made by individual organisms to their environments. Evolution, on the other hand, includes adaptation as well as long-term changes in populations and species, such as speciation and genetic drift.
