Alexey Simonovich Kondrashov (Russian: Алексе́й Си́монович Кондрашо́в) (born April 11, 1957) worked on a variety of subjects in evolutionary genetics.

[5] He founded the laboratory of evolutionary genomics in the College of Bioengineering and Bioinformatics at Lomonosov Moscow State University.

[6][7] In 1990, Kondrashov became an Associate Visiting Scientist in the Department of Genetics at the University of Wisconsin – Madison.

[11] Kondrashov states that amino acid composition of proteins varies between taxa, so it can evolve.

To support this hypothesis Kondrahov et al. compared sets of orthologous proteins from 15 taxa, which represent three domains of life.

On August 22, 2012, Kondrashov wrote an article in Nature, describing a link between older fathers and a rise in disorders such as autism.

The exact reason for it is not well understood, but the collecting of sperm of young men and freezing it for the future can be a clever choice.
