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.

Meet olinguito, or Bassaricyon neblina, the first species of carnivore discovered in the Western Hemisphere in 35 years. This cute teddy bear-like nocturnal mammal is native to Central and South America, and spends most of its time in the treetops, coming down to the forest floor occasionally to eat fruits such as guava.

The Mandarin duck is a sexually dimorphic species, meaning males and females differ in appearance. The male has a rich, colorful appearance, which includes brown cheeks and a long brown and white crown sweeping back from the top of the head. The chest is dark purple, with black and white strips, and the wings are brown with an iridescent blue-green edge. This striking coloration helps the male attract the less-colorful females, which display brownish-black plumage with white markings around the eyes and along the throat. ...

Four species of legless lizard have been identified in the sand dunes of Antioch, California. This picture introduces Anniella grinnelli, one of the recently found species. It has a bright yellow belly and a lilac back with deep purple lines, and was named after Joseph Grinnell, the first director of the Berkeley Zoology Museum.

The two marmosets - small, New World monkeys - had been a closely bonded couple for more than three years. Then, one fateful day, the female had a terrible accident. Her partner left two of their infants alone in the tree and jumped down to apparently comfort and mourn her. Humans mourn their dead, of course, and some recent studies have strongly suggested that chimpanzees do as well. This new observation suggests that mourning is more widespread among primates than previously thought.

Here's how 9,000 years of selective breeding has changed corn from a wild grass - that required a hammer to peel - to the juicy yellow ears of deliciousness we know today.

Charles Darwin said that it was "absurd in the highest possible degree".
