A small step for lungfish, a big step for the evolution of walking
The eel-like body and scrawny "limbs" of the African lungfish would appear to make it an unlikely innovator for locomotion. But its improbable walking behavior, newly described by University of Chicago scientists, ...
Namibia sponge fossils are world's first animals: study
Scientists digging in a Namibian national park have uncovered sponge-like fossils they say are the first animals, a discovery that would push the emergence of animal life back millions of years.
