Dr Evans led an international
team of anthropologists and developmental
biologists from Finland, USA, UK and Germany, using a new extensive database on fossil hominins and modern humans collected over

To find out whether pesticides are taken up by amphibians even in relatively pristine areas, a
team led by wildlife
biologist Donald Sparling
of the U.S. Geological Survey in Laurel, Maryland, tested Pacific treefrogs in
several national parks.
