Koalas that once lost much of their genetic diversity may now be rebuilding it as their populations rebound. Credit: Shutterstock A new genomic study of koala populations in Australia suggests that rapid population growth may help restore genetic variation that was lost during past declines. Researchers found that when populations recover quickly, the increase in numbers can encourage recombination, a process that rearranges DNA into new combinations. This genetic mixing may help previously
