Biology and Human Behavior. In the article, “Is Google Making Us Stupid?”, Carr argues that constant reading in the Internet has lessened his ability to concentrate and read longer text/works. This change in how people think may be more evident in Western societies, as well as other developing countries who are vastly catching up in the technology and technological knowhow.As for artificial selection, some of such processes that I can think are through cloning and artificial reproduction of human beings and domesticating people by making them less mobile, because of dependence on technology. The film “Gattaca” is an example of artificial selection, which aims to create a “Utopian” society. Human domestication is viewed as possible, when people interact less physically and rely more on technology to manage their social relations (i.

These new ways of thinking also shape how people act, such as becoming more predisposed to reading and writing shorter or summarized articles and stories.There are various biological processes that affect human actions. The exact cause of yawning remains unclear. Nevertheless, it is widely believed that the paraventricular nucleus (PVN) of our hypothalamus is the “yawning center” (Andrews). The PVN has some of the chemical messengers that can stimulate yawns, such as “dopamine, glycine, oxytocin and adrenocorticotropic hormone (ACTH)” (Andrews). ACTH occurs during the night and flows before awakening, and it can also start yawning and stretching behavior among people (Andrews). The process of yawning also seems to need the production of nitric oxide by some of the specific neurons found in the PVN (Andrews). After being activated, the cells of the PVN stimulate brain cell stems and/or cells in the hippocampus, which induce people to yawn (Andrews). Yawning also seems to have a “feedback component,” where preventing or stopping a yawn creates an “unsatisfying” effect on people (Andrews). At the same time, it seems to be better to stretch the jaw and face muscles to have a good yawn (Andrews).There are many ways that biology affects behavior, such as through self-preservation and.
