James V. Neel (1915–2000), US human geneticist who contributed to the development of research on human genetics, and founded the first genetics clinic in the US Frederick C. Neidhardt (1931–2016), US microbiologist, pioneer in molecular physiology and proteomics of E. coli
Many lineages diverged at different stages of development, so it is possible to determine when certain metabolic processes appeared by comparing the traits of the descendants of a common ancestor. Evidence from animal coloration was gathered by some of Darwin's contemporaries; camouflage , mimicry , and warning coloration are all readily ...

The combination, in the 1930s and 1940s, of Mendelian genetics with Darwin's theory of natural selection resulted in the modern synthesis of evolutionary biology. [50] [51] In the Soviet Union and China, Mendelian genetics was rejected in favor of Lamarckism, leading to imprisonment and even execution of Mendelian geneticists (see Lysenkoism).
As with Haldane and Fisher, Dobzhansky's "evolutionary genetics" [59] was a genuine science, now unifying cell biology, genetics, and both micro and macroevolution. [44] His work emphasized that real-world populations had far more genetic variability than the early population geneticists had assumed in their models and that genetically distinct ...
1992: American and British scientists unveiled a technique for testing embryos in-vitro (Amniocentesis) for genetic abnormalities such as Cystic fibrosis and Hemophilia. 1993: Phillip Allen Sharp and Richard Roberts awarded the Nobel Prize for the discovery that genes in DNA are made up of introns and exons.
The scientists studied the genetic information from Qizai’s family members and compared it with the genetic information from 12 black-and-white pandas from the Qinling Mountains and 17 black-and ...
Genetic variation can be identified at many levels. Identifying genetic variation is possible from observations of phenotypic variation in either quantitative traits (traits that vary continuously and are coded for by many genes, e.g., leg length in dogs) or discrete traits (traits that fall into discrete categories and are coded for by one or a few genes, e.g., white, pink, or red petal color ...
