Indeed, similar to the role played by natural selection during evolution, excessive cell death, rather than its absence, may be the selective force driving clonal evolution during the initial stages of most cancers.
This set of traits guided further research into reproductive regulatory systems that were co‐opted by natural selection during the evolution of social behavior.
Thus, the lack of phenotypic variation in small populations was owing to it having been eliminated by natural selection during the immediately prior period of decline.
Supposedly Alfred R. Wallace, co-discovered of the theory of evolution by natural selection, during his expedition to Indonesia (1854-1862), experienced a strong earthquake on the island of Lombok and observed a change in the sea level around the island.
Note that the sequential and additive arrival at the phenotypically meaningful sequence of A plus T plus G, represents, in reality, the accumulation of events fixed by natural selection during protein evolution, which entails clustered changes of multiple parts, and at diverse locations, within functional domains.
The advent of agriculture, beginning roughly 10,000 years ago, set into motion an ever-accelerating rate of cultural change in how we humans live; but however we live, we continue to do so with the biological drives and capacities that were honed by natural selection during our hunter-gatherer days.
In this work, we showed that TE has been targeted by natural selection, both positive and negative, during relatively recent human evolution.
Meat and dairy products, for example, are much more likely to harbour bacteria, so it may be that the female body has been adapted by natural selection to get rid of them during pregnancy.
Characteristics derived from mutation and other mechanisms that are advantageous for survival are often preserved during evolution by natural selection.
Despite their importance, relatively little is known about how regulatory networks are formed during evolution and shaped by natural selection.
Evolution by natural selection was indeed a favourite topic in society salons during the 1860s and beyond.
