According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands.The closest relative among the other living Primates, the genus Pan, represents a branch that continued on in the deep forest, where the primates evolved.Click the "Buy Now" button for the San Jose event you would like to attend.

Some volcanic events which were sufficiently powerful to have distributed material around the globe leave a signature in the ice which can be detected in many different cores, allowing synchronization of the time scales between two different locations.It is the smart way to find the right person to date.Note: This event is open to everyone - both new and returning participants.The Stone Age is a broad prehistoric period during which stone was widely used to make implements with a sharp edge, a point, or a percussion surface.
The period lasted roughly 3.4 million years, and ended between 4500 BC and 2000 BC with the advent of metalworking.Therefore, if you are returning it is possible there could be at least 1 person there you have met with previously.
