Introgression is an important source of genetic variation in natural populations and may contribute to adaptation and even adaptive radiation. [7] It can occur across hybrid zones due to chance, selection or hybrid zone movement. [8]
It is the second stage in the history of hybridity, characterized by literature and theory that study the effects of mixture (hybridity) upon identity and culture. The principal theorists of hybridity are Homi Bhabha , Néstor García Canclini , Stuart Hall , Gayatri Spivak , and Paul Gilroy , whose works respond to the multi-cultural awareness ...
Interest in the relationship between Darwinism and the study of literature began in the nineteenth century, for example, among Italian literary critics. [2] For example, Ugo Angelo Canello argued that literature was the history of the human psyche, and as such, played a part in the struggle for natural selection, while Francesco de Sanctis argued that Emile Zola "brought the concepts of ...
Hindi literature (Hindi: हिंदी साहित्य, romanized: hindī sāhitya) includes literature in the various Central Indo-Aryan languages, also known as Hindi, some of which have different writing systems. Earliest forms of Hindi literature are attested in poetry of Apabhraṃśa such as Awadhi and Marwari.
The opening of literature and literary studies to graphic novel and comics is commonly assumed to be a postmodern phenomenon, emerging from evolution such as the unremitting hybridization of media and art forms and the progressive dismantling of the frontiers between high and low art. The blend of literature, (a traditional form of high art ...
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]
Eukaryote hybrid genomes result from interspecific hybridization, where closely related species mate and produce offspring with admixed genomes.The advent of large-scale genomic sequencing has shown that hybridization is common, and that it may represent an important source of novel variation.
There is some evidence of adaptive evolution in genes linked to brain development, but some of these genes are often associated with diseases, e.g. microcephaly (see Table 2). However, there is a particular interest in the search for adaptive evolution in brain genes, despite the ethical issues surrounding such research.
