11 photos that prove tigers have a softer side
July 29 is International Tiger Day, a holiday that raises awareness of their endangered status and advocates a global system for conserving their natural habitats.
 
While tigers are known for their striking stripes, massive size, barbed tongues, razor sharp teeth and predatory instinct, it’s also important to recognize how cute and lovable they can be. Here are just a few photos demonstrating the gentle side of these beautiful creatures.

The Origin of Humans Is Surprisingly Complicated
Human family tree used to be a scraggly thing. With relatively few fossils to work from, scientists’ best guess was that they could all be assigned to just two lineages, one of which went extinct and the other of which ultimately gave rise to us. Discoveries made over the past few decades have revealed a far more luxuriant tree, however—one abounding with branches and twigs that eventually petered out. This newfound diversity paints a much more interesting picture of our origins but makes sorting our ancestors from the evolutionary dead ends all the more challenging.
