3D-printed shell halves allowed researchers to peek inside the cichlid's home and observe the behavior of the mother and her fry during brood care.

But male flies, in turn, have sharpened their eyesight to call their bluff. A new study suggests that this is an ongoing evolution where both sexes ...

However, the researchers also found that countries where poultry are vaccinated against H5 bird flu—specifically China—saw a faster rate of viral evolution compared to those where poultry is ...

For example, male lions are larger than females, whereas in some species—including certain spiders and angler fish—females are larger than males. Traits that enhance mating success like ...
