Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct, and that using it as a proxy for genetic differences among populations is misleading. [1] [2]
Hershey–Chase experiment proves that phage genetic material is DNA. 1952: The Hershey–Chase experiment proves the genetic information of phages (and, by implication, all other organisms) to be DNA. [29] 1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30]
Cavalli-Sforza has summed up his work for laymen in five topics covered in Genes, Peoples, and Languages. [8] According to an article published in The Economist, the work of Cavalli-Sforza "challenges the assumption that there are significant genetic differences between human races, and indeed, the idea that 'race' has any useful biological meaning at all".
A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics. In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while many others worked out the relationship between ...
The word "race", interpreted to mean an identifiable group of people who share a common descent, was introduced into English in the 16th century from the Old French rasse (1512), from Italian razza: the Oxford English Dictionary cites the earliest example around the mid-16th century and defines its early meaning as a "group of people belonging to the same family and descended from a common ...
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago.

Race adjustment, also known as race-correction, [1] [2] is the calculating of a result which takes into account race. [1] It is commonly used in medical algorithms in several specialties, including cardiology , nephrology , urology , obstetrics , endocrinology , oncology and respiratory medicine . [ 1 ]
