Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
Scientists have long debated how the bird ancestors evolved the ability to fly. The ground-up theory assumes they were ground animals moving fast by jumping and flapping( 振翅)their wings. The tree-down theory assumes they were tree climbers that glided(滑行)among branches.At field sites Ken ...
Unfortunately, we don't have time machines to take us back to the time of the pterosaurs, but we do have paleontologists, scientists who study and interpret fossils. They've been able to use old rocks and bones to discover some pretty amazing things about how these creatures evolved, what...
The scientists suggested that these chemical cues originated for non-communicative purposes at first, and only inadvertently contained information that other organisms detected. Then, the chemical cues could have evolved into signals in a few different ways. If the organism that detected the original ...
