Is there anything cuter than fossil hunters in love? Louis and Mary Leakey were paleontology nerds and badass adventurers, who boldly scoured the African wilderness for early human fossils. They spent the beginning of their mutual career in poverty, but never seemed to care, happily living off the grid together. Their incredible insights into human evolution soon attracted funds, and they are now remembered as major contributors to paleoanthropology. Do yourself a favor and Google Image search the pair: they are so obviously in love, it'll make your heart explode.
