1 day ago · Convergent evolution is widely observed, such as in streamlining in aquatic animals 1,2.Leveraging observations of convergence is a powerful approach to investigate evolutionary processes ...
2 days ago · Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family that includes all the great apes.
2 days ago · Rather, evolutionary systems theory also includes in its models the structural capacity to make those choices, which derives from and depends on previous choices made, a process also bound by our biological evolution or alternatively by our cognitive limitations and available structural selection mechanisms, regardless of the relative complexity of human learning capacity.
4 days ago · Australopithecus, (genus Australopithecus ), group of extinct primates closely related to, if not actually ancestors of, modern human beings and known from a series of fossils found at numerous sites in eastern, north-central, and southern Africa.
1 day ago · Two settings are considered: the completely innovating, tinkering, situation of the emergence of multicellularity in the evolution of species, which we assume to be constrained by external pressure on the cell populations, and the completely planned—in the body plan—situation of the physiological construction of a developing multicellular animal from the zygote, or of bet hedging in ...
15 hours ago · Furthermore, we observe that the promoters of genes exclusively expressed in germ cells generally exhibit rapid evolution, with some divergence in gene expression. Our results suggest that increased germline promoter evolution, in partnership with other factors, could contribute to transposon silencing and evolution of species through differential expression of genes driven by invading ...
5 days ago · Patagia—the mammalian gliding membrane—repeatedly originated through a process of convergent genomic evolution, whereby the regulation of Emx2 was altered by distinct cis-regulatory elements ...
