Natural selection leaves subtle signatures on our genome, but these marks can erode over generations due to recombination, where segments of DNA are shuffled and diluted.

Interestingly, about half of these adaptive signals were detectable only in the oldest time periods, meaning they later vanished due to genetic drift or were masked by extensive population mixing.

Due to the climate crisis, urban river deltas are facing hazards such as rising sea levels, extreme weather events, and soil subsidence.

But many of those results may have been skewed due to a lack of female representation, the study suggests.

"Opera and ballet are under particular strain at the present time due to funding pressures and we are fighting to maintain full time jobs and pay."
