warthog

And then there will be some animals, perhaps particularly lazy domestic cats or warthogs focused on foraging, who might not give the dark sky a second thought.

At the site, known as Shinfa-Metema 1, the researchers uncovered thousands of bones, some covered in cut marks, from gazelles, warthogs and even giraffes, suggesting that the humans were hunting these species.

This was true for 95 percent of the animal species observed, including giraffes, leopards, hyenas, zebras, kudu, warthogs, impalas and rhinos.

Fully 95% of species, including giraffes, leopards, hyenas, zebras, kudu, warthog, impala, elephants, and rhinoceroses, ran more often or abandoned waterholes faster in response to humans than in response to lions.

Those who watched the dancing warthog gave a little more to charity and were more likely to give the whole amount, though the results are less conclusive because of a small sample size.
