A described mechanism of technological change has been termed, “combinatorial evolution”. [2] Others have called it, “technological recursion”. [3] Brian Arthur has elaborated how the theory is related to the mechanism of genetic recombination from evolutionary biology and in which aspects it differs. [4]
Rapidly evolving peripherally isolated populations may be the place of origin of many evolutionary novelties. Their isolation and comparatively small size may explain phenomena of rapid evolution and lack of documentation in the fossil record, hitherto puzzling to the palaeontologist.
Furthermore, climate change may trigger the mass migration of not just humans but also diseases affecting humans. [77] Besides the selection and flow of genes and alleles, another mechanism of biological evolution is epigenetics, or changes not to the DNA sequence itself, but rather the way it is expressed. Scientists already know that chronic ...
Since 2010, scientists have known that the Y chromosome is rapidly evolving in humans, but a new study shows that the same can be said across all Great Apes—the closest relatives to humans.
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
Social change may not refer to the notion of social progress or sociocultural evolution, the philosophical idea that society moves forward by evolutionary means.It may refer to a paradigmatic change in the socio-economic structure, for instance the transition from feudalism to capitalism, or hypothetical future transition to some form of post-capitalism.
Concerted evolution (phenomenon of duplicated genes) may often be caused by the genetic exchange known as gene conversion. [3] This other phenomenon is known as the "non-reciprocal exchange of genetic material between homologous sequences."
Exist in some way; purely hypothetical technologies cannot be considered emerging and should be covered in the list of hypothetical technologies instead. However, technologies being actively researched and prototyped are acceptable. Have a Wikipedia article or adjacent citation covering them. Not be widely used yet.
