This is Washoe, the first non-human to use sign language. When her caretaker Kat suffered a miscarriage, and Washoe was told that her baby had died, she signed "CRY", drawing a path down her cheek with her finger to mimic a tear. Chimpanzees don't shed tears, and Kat said this one sign told her more about Washoe's mental capabilities than all of her longer, grammatically perfect sentences.

This 20-year-old male chimp suffering with alopecia, is a star attraction at an Indian zoo, as he sort of resembles a human. Perhaps being locked up in a zoo makes life a deeply distressing experience

The tail was discovered in northern Mexico and most likely belonged to a hadrosaur, a duck-billed dinosaur. The tail is 4.9 meters (16 feet) long and is made up of 50 vertebrae. Tails are rare finds, and this is the first discovered in such good condition.

It turns out that our evolutionary cousins can recall number placement better than people can. In the experiment, the task requires the chimp to touch the numbers in ascending order and he has only seconds to make his decisions. The numerals appeared only for a certain limited duration, and were then automatically replaced by white squares. After touching the number one, the rest of the numbers are obscured by squares, making the chimp reliant on his memory to correctly pick the numbers in the right order. After a whistle sounds, the numbers reappear in different positions, so the chimp has to remember the position of all nine numbers after seeing them only briefly. And the chimp quickly aces the test time and time again, r ...

Zookeepers at Central Park Zoo in the US assumed their cotton-top tamarins were falling silent every time someone entered their enclosure, but spectrograms, which provide visual representations of sound, revealed what was really going on. These little monkeys were actually whispering their alarm calls instead of shouting them, which is the first evidence of whispering in a non-human primate species.

Ancient baby's teeth have revealed that Neanderthals followed today's breastfeeding guidelines. Scientists analyzed a fossilized baby tooth from a Neanderthal child, and found the infant was breastfed exclusively for the first seven months of life and given supplementary foods and mother's milk for another seven months before being weaned.

This fascinating discovery sheds light on the remarkable similarities between Neanderthal parenting practices and contemporary breastfeeding guidelines. By examining the composition of the fossilized baby tooth, scientists have uncovered valuable insights into the dietary patterns of our ancient relatives.

The Neanderthal infant's exclusive breastfeeding for the first seven months of life mirrors the advice ...

Scientists have identified the genetic mutation responsible for the first blue chicken eggs in South American Mapuche fowl and their European descendants, Araucana, 200 to 500 years ago.

They used the unique genetic resources conserved by heritage or “fancy” poultry breeders to identify the exact location of the mutation in the genome in blue egg laying chickens and an additional genomic study to reveal the genetic cause of the blue colored eggshell is a harmless ancient retrovirus in the domestic chicken.
