Serial homology is a special type of homology, defined by Owen as "representative or repetitive relation in the segments of the same organism." [ 1 ] Ernst Haeckel preferred the term "homotypy" for the same phenomenon.
In biology, homology is similarity in anatomical structures or genes between organisms of different taxa due to shared ancestry, regardless of current functional differences. Evolutionary biology explains homologous structures as retained heredity from a common ancestor after having been subjected to adaptive modifications for different ...
The ability of humans to store items in memory and recall them is important to the use of language. Imagine recalling the different parts of a sentence, but in the wrong order. The ability to recall in serial order has been found not only in humans, but in a number of non-human primate species and some non-primates. [2]
Whereas ordinary homology is seen in the pattern of structures such as limb bones of mammals that are evidently related, deep homology can apply to groups of animals that have quite dissimilar anatomy: vertebrates (with endoskeletons made of bone and cartilage) and arthropods (with exoskeletons made of chitin) nevertheless have limbs that are constructed using similar recipes or "algorithms".
Sequence homology is the biological homology between DNA, RNA, or protein sequences, defined in terms of shared ancestry in the evolutionary history of life. Two segments of DNA can have shared ancestry because of three phenomena: either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene ...
Richard Middleton (1990, p. 9-10) argues that "such theories always end up in some kind of reductionism – 'upwards', into an idealist cultural spirit, 'downwards', into economism, sociologism or technologism, or by 'circumnavigation', in a functionalist holism." However, he "would like to hang on to the notion of homology in a qualified sense.
Homologous recombination is the proposed mechanism whereby the DNA virus human herpesvirus-6 integrates into human telomeres. [ 92 ] When two or more viruses, each containing lethal genomic damage, infect the same host cell, the virus genomes can often pair with each other and undergo homologous recombinational repair to produce viable progeny.
Humans is a science fiction television series that debuted in June 2015 on Channel 4 and on AMC.Written by Jonathan Brackley and Sam Vincent, based on the Swedish science fiction drama Real Humans, the series explores the themes of artificial intelligence, robotics, and their effects on the future of humanity, focusing on the social, cultural, and psychological impact of the invention and ...
