Abstract: Alternative morphotypes have been reported in males of different taxa. In some mammals highly masculinized and slightly masculinized males represent two opposite ends along a gradient of phenotypic variation in males. This phenotypical gradient originates during prenatal development. Laboratory studies have documented how highly and slightly masculinized males differ in several traits, including their reproductive success. However, the extent to which these reported differences materialize in natural populations remains unknown. We quantified the impact...

Data from: Y chromosome sequences reveal a short Beringian Standstill, rapid expansion, and early population structure of Native American founders

The Americas were the last inhabitable continents to be occupied by humans, with a growing multidisciplinary consensus for entry 15-25 thousand years ago (kya) from northeast Asia via the former Beringia land bridge. Autosomal DNA analyses have dated the separation of Native American ancestors from the Asian gene pool to 23 kya or later, and mtDNA analyses to ~25 kya, followed by isolation (‘Beringian Standstill’) for 2.4-9 ky and then a rapid expansion throughout the...
