While scientists were analyzing prehistoric worms recovered from permafrost, two 40,000 year old nematodes ‘revived’ and began moving and eating, making them the oldest multi-cellular life alive on Earth.

Ancient Roundworms Allegedly Resurrected From Russian Permafrost The permafrost of Russia’s Siberian heartland has yielded an array of impressive finds in recent years. Last September, a local resident wandering along the banks of a river in the republic of Yakutia discovered the roughly 50,000-year-old remains of an extinct lion cub almost perfectly preserved by the …

Figs are considered an animal product by many vegans. Female wasps crawl into figs, lay their eggs and die. The mother wasp is enzymatically digested by the fig.

Why Aren’t Figs Considered Vegan? Sorry if this ruins figs for you. Like those of dumplings and sandwiches, the definition of veganism isn’t set in stone. Some practitioners eschew honey and sugars refined with animal-bone char, since both involve products derived from animals. Others avoid Italian aperitifs like Campari dyed with carminic acid, which is …

Elephants are highly empathetic and generous even towards other species. Once an elephant found a rancher with a broken leg and dragged him under the shade of a tree, guarding him and gently touching him with her trunk

Elephant cognition Most contemporary ethologists view the elephant as one of the world’s most intelligent animals. With a mass of just over 5 kg (11 lb), an elephant’s brain has more mass than that of any other land animal, and although the largest whales have body masses twenty times those of a typical elephant, a …

Of the 5000 or so species of mammals on the planet only female humans have permanent breasts.

The science of why human breasts are so big Breasts are uniquely human— more than 5,000 mammals inhabit this planet, yet Homo sapiens are the only life forms with permanent breasts. Every other mammal develops temporary breasts during ovulation or nursing in order to produce milk for their young. Watch the video above to learn …

The reason why we view neanderthals as hunched over and degenerate is that the first skeleton to be found was arthritic.

1. You’re pretty much a Neanderthal. While it’s been more than 5 million years since we parted ways with chimps, it has been only 400,000 since human and Neanderthal lineages split. 2. If you’re Asian or Caucasian, your ancestors interbred with Neanderthals as recently as 37,000 years ago, when they crossed paths in Europe. 5. …

Bees dance to each other in the hive to tell each other where to find good pollen. The angle of the dance is the angle relative to the sun, the tempo of dance is the distance, the duration of dance is the quality of the pollen, and the dancer hands out free samples to whoever’s watching!

Food sources of lower quality will produce fewer, shorter, and less vigorous dances; recruiting fewer new foragers. The round dance is used for food sources 25-100 meters away from the hive or closer. Bees elicited into foraging after a round dance fly out of the hive in all directions searching for the food source they …

Female widow spiders are typically dark brown or a shiny black in colour when they are full …
