Frogs are interesting creatures, but not by nature. They perform gender changes because of environmental influences. Scientists have noticed frogs transitioning from male to female for some time, but now they are observing it in the wild.
When they make the switch, frogs develop all of the functioning reproductive features as well. The reason behind this is a weed killer called atrazine. The product was banned in Europe but has already entered several river streams and lakes. It reduced testosterone and dramatically boosted estrogen.
