Top: An ancestral gene duplication produces two paralogs (histone H1.1 and 1.2). A speciation event produces orthologs in the two daughter species (human and chimpanzee). Bottom: in a separate species , a gene has a similar function (histone-like nucleoid-structuring protein) but has a separate evolutionary origin and so is an analog.
The term "ortholog" was coined in 1970 by the molecular evolutionist Walter Fitch. [41] Homologous sequences are paralogous if they were created by a duplication event within the genome. For gene duplication events, if a gene in an organism is duplicated, the two copies are paralogous. They can shape the structure of whole genomes and thus ...
English: Top: An ancestral gene duplicates to produce two paralogs (Genes A and B). A speciation event produces orthologs in the two daughter species. Bottom: in a separate species, an unrelated gene has a similar function (Gene C) but has a separate evolutionary origin and so is an analog.
In an article, about Music therapy and group work, the authors discuss how music and active listening play an important role in helping someone suffering from a mental illness improve their well-being.

In the context of psychology, a coping strategy is any technique or practice designed to reduce or manage the negative effects associated with stress. While stress is known to be a natural biological response, biologists and psychologists have repeatedly demonstrated that stress in excess can lead to negative effects on one's physical and psychological well-being.
