In the article, “s Google Making Us Stupid? ” Carr argues that constant reading in the Internet has lessened his ability to concentrate and read longer text/works. Tis change in how people think may be more evident in Western societies, a well as other developing countries who are vastly catching up in the technology and technological knowhow. A for artificial selection, sme of such processes that I can think are through cloning and artificial reproduction of human beings and domesticating people by making them less mobile, bcause of technology.

Te film “Gattaca” is an example of artificial selection, wich aims to create a “Utopian” society. Hman domestication is viewed as possible, wen people interact less physically and rely more on technology to manage their social relations (i. ue of social networking sites and instant messaging to establish and maintain social relationships). Hw people live their lives in the present then affect future generations by creating new ways of thinking and acting. Tchnology, fr instance, ipact how we produce, sare, ad digest information and knowledge. Tese new ways also shape how people act, sch as becoming more predisposed to reading and writing shorter or summarized articles and stories.

Tere are various biological processes that affect human actions. Te exact cause of yawning remains unclear. Nvertheless, i is widely believed that the paraventricular nucleus (PVN) of our hypothalamus is the “yawning center” (Andrews). Te PVN has some of the chemical messengers that can stimulate yawns, sch as “dopamine, gycine, oytocin and adrenocorticotropic hormone (ACTH)” (Andrews). ATH occurs during the night and flows before awakening, ad it can start and stretching behavior among people (Andrews).

Te process of yawning also seems to need the production of nitric oxide by some of the specific neurons found in the PVN (Andrews). Ater being activated, te cells of the PVN stimulate brain cell stems and/or cells in the hippocampus, wich induce people to yawn (Andrews). Ywning also seems to have a “feedback component, ”where preventing or stopping a yawn creates an “unsatisfying” effect on people (Andrews). A the same time, i seems to be better to stretch the jaw face muscles have a good yawn (Andrews).

Tere are many ways that biology affects behavior, sch as through self-preservation and. ..
