Scientists maintain that categories of race have no grounding in biology
Humans obviously differ in a variety of physical ways – skin pigmentation, hair and eye color, height and so on. Scientists have shown, however, that humans have not evolved into separate subspecies, or “races,” and that the concept of race is purely of political origins. There are no racial distinctions when it comes to biology.
While some medical issues are linked with race, scientists point to the impact of other factors as more important
For instance, those who live in rural West Africa have some of the lowest rates of high blood pressure in the world. Americans of African descent, however, have recorded some of the highest. Scientists point to factors such as environment, diet, and daily activities, as having a much bigger impact on something like blood pressure than an individual’s race.
Geography and ultraviolet rays are responsible for variations in skin color
It has been shown that darker skin developed in those living in Africa due to the hot climate and sun exposure, leaving many to wonder about darker-skinned natives in Alaska and Northern Canada. Scientists have shown that those living in northern regions with longer periods of darkness still receive higher levels of UVR reflected off of ice and snow, and their vitamin D-rich diets — fish and seal — help compensate for the reduced sunshine during the winter.
Blood types are not linked to race
Blood banks often try to recruit minorities to donate, claiming that matches are more likely within races. Science has proven otherwise. There is as much variation in blood type between races as within them, and blood types are purely an outcome of the genetic make-up of your parents.
Race and ethinicity, while both social constructs, are different things entirely
Race as been associated with the idea that there are innate biological differences, which has been debunked by scientists. Ethnicity, on the other hand, is associated with a shared culture, religion or language, and remains an important distinction.
Europeans and East Asians have a different gene that causes light skin color
Scientists have found that the allele (DNA codings that determine distinct traits that can be passed on from parents to offspring) associated with lighter skin color in Europeans originated fairly recently — approximately 6,000-10,000 years ago — while the allele in East Asians is altogether different. This indicates that the two groups evolved light skin separately.
The Human Genome Project proved you cannot tell race from genes
The Human Genome Project, a massive undertaking in the U.S. that successfully mapped out the complete human genetic code, showed that there are no genetic distinctions with regard to race.
Eugenists failed to show some races were inherently more intelligent than others in the early 1900s
Eugenists, or those that attempt to “improve” the genetic quality of the human population, tried to use IQ tests during the early 1900s to show that blacks and southern and eastern Europeans were intellectually inferior to Americans of Anglo-Saxon and Scandinavian descent. They were unsuccessful, and by the 1940s were largely dismissed as searching for an excuse for racial hatred.
Ancestry websites are some of the most commonly visited on the Internet
After the most common essential websites such as email or social media, ancestry websites are extremely popular online – although it’s important to note that pornography sites remain more widely visited. A molecular biologist from Johns Hopkins University once estimated that each individual has about 6.7 billion relatives across the globe, basically meaning we’re all related in some way.
Research shows that infants as young as six months notice racial differences
As children are incredibly impressionable, it is thought that infants internalize the different ways that those around them respond to people of different races, making the social-construct argument of racism that much more powerful. The argument goes that the entire social structure we inhabit is affected by at least one social construction — race, according to anthropology.net.
