They were thus able to demonstrate that even simple decision rules can mediate a complex behavioral pattern such as parental care.

Scientists named the new species Ramadapis sahnii and said that it existed 11 to 14 million years ago. It is a member of the ancient Sivaladapidae primate family, consumed leaves and was about the size of a house cat.
