Scientists investigate the mechanism on how some invasive species, such as the green crab, had shown extensive dispersal in the last decade as they adapt across environmental gradients despite lacking genetic diversity.
Most rhinoceros species went extinct before the Pleistocene era. Geneticists now try to reconstruct the three extinct species to fill in the gaps of the species' evolutionary family tree by analyzing their genomes and the genomes of five living rhino species.
A Massey University research team has discovered some interesting new truths about the ways arranged marriages affect genetic diversity and the ways that humans follow even important cultural rules selectively-and they may surprise you. The results show that the isolated Indonesian Rindi tribe produces genetic diversity similar to random mating by loosely complying with their rules which mandate arranged, inbred marriages.
