“Race does not stand up scientifically, period”*…
The genetic distance between some groups in Africa, such as the Fulani of West Africa (above) and the Hazda of Tanzania, is greater than supposedly racially divergent groups such as East Asians and Europeans.
If race categories were meant primarily to capture differences in genetics, they are doing an abysmal job. The genetic distance between some groups within Africa is as great as the genetic distance between many “racially divergent” groups in the rest of the world. The genetic distance between East Asians and Europeans is shorter than the divergence between Hazda in north-central Tanzania to the Fulani shepherds of West Africa (who live in present-day Mali, Niger, Burkina Faso, and Guinea). So much for Black, White, Asian, and Other.
Armed with this knowledge, many investigators in the biological sciences have replaced the term “race” with the term “continental ancestry.” This in part reflects a rejection of “race” as a biological classification. Every so-called race has the same protein-coding genes, and there is no clear genetic dividing line that subdivides the human species. Another reason for using the term “continental ancestry” in lieu of “race” is improved precision for locating historical and geographic origins when we look at the genome. Thus, continental ancestry allows for more genetically accurate descriptors. For example, President Barack Obama was not just the first socially “black” president. He was also the first (as far as we know) who has European and African ancestry.
In sum, racial categories now in use are based on a convoluted and often pernicious history, including much purposefully created misinformation.
It is a good time, then, to dispel some myths about genetic variation that have been promulgated by both the left and the right alike…

As we hear Bob Marley sing “One love, one heart, let’s get together and feel all right,” we might recall that it was on this date in 1795 that the first (but still provisional) official standard “metre bar” was forged in Paris. Made of brass, its length was one ten-millioneth of the northern quadrant of the Paris meridian.
In the aftermath of the French Revolution (1789), the traditional units of measure used in the Ancien Régime had replaced; the livre monetary unit was replaced by the decimal franc, and a new unit of length was introduced– the metre.
This first prototype was short by 0.2 millimeters because researchers miscalculated the flattening of the earth due to its rotation. Still this length became the standard– replicated in platinum– until 1889, when new, more accurate measurements were used to create a new standard metre, that gained acceptance across the world.
