Analysis of giant extinct marine reptile graveyard suggests mysterious site was ancient birthing ground
Today's marine giants—such as blue and humpback whales—routinely make massive migrations across the ocean to breed and give birth in waters where predators are scarce, with many congregating year after year along the same stretches of coastline......»»
Twin brother spotted hyenas are often attracted to the same new group when they disperse from their birth group
In most mammals, males disperse to a new group after reaching sexual maturity. Dispersal often entails costs and is risky. New results from spotted hyenas show that males from the same birth group—and particularly twin brothers—very often dispers.....»»
What is a "name microaggression?" And could you be doing it without knowing?
