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 ...
Orthology (biology) - homologous sequences originate from the same ancestors (homolog e.g. all globin protein), which are separated from each other after a speciation event, e.g. human beta and chimp beta globin. An orthologous gene is a gene in different species that evolved from a common ancestor by speciation.
The Encyclopædia Britannica gives the following description of synteny, using the modern definition: [2] Genomic sequencing and mapping have enabled comparison of the general structures of genomes of many different species.
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. [1] For example, in music, attunement, is how listeners are able to connect with others while listening to and making the music. [1]
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 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.

Audio therapy is the clinical use of recorded sound, music, or spoken words, or a combination thereof, recorded on a physical medium such as a compact disc (CD), or a digital file, including those formatted as MP3, which patients or participants play on a suitable device, and to which they listen with intent to experience a subsequent beneficial physiological, psychological, or social effect.
