When explaining human origins, a staggering 42% of all Americans still ascribe to a creationist interpretation—despite the fact that there’s plenty of evidence to support the theory of natural selection. Here are some of the most potent scientific discoveries that prove Darwin was right.
Fruits can get their colors from a lot of places. New research suggests that the color preferences of the animals that eat fruit are among the strongest influences on fruit color. It's an assumption scientists have always made, but now they have some evidence to support it.
How many different ways are there to say that culling invasive or unwanted species is rarely the best solution to manage a disrupted ecosystem? It looks like we have to keep coming up with new ways of saying it, because our hunting behavior itself is driving invasive lionfish into hiding.
