Teaching Evolution through Human Examples The "Teaching Evolution through Human Examples" (TEtHE) three-year exploratory research and development project was funded by National Science Foundation Discovery Research K-12 grant #1119468. The project has created four curriculum units for Advanced Placement (AP) Biology classes, aligned to the learning objectives, using human case studies to teach core evolutionary principles. The curriculum units are: (1) Adaptation to Altitude, (2) Malaria, (3) Evolution of Human Skin Color, and (4) What Does It Mean To Be Human?. The project has also created a CRS (Cultural and Religious Sensitivity) Teaching Strategies Resource to help teachers create a comfortable and supportive classroom environment for teaching evolution. More information about the project can be found here (link is external).

Tools & Food New Tools, New Foods Dawn of technology By 2.6 million years ago Early humans in East Africa used hammerstones to strike stone cores and produce sharp flakes. For more than 2 million years, early humans used these tools to cut, pound, crush, and access new foods—including meat from large animals. Com feien foc els nostres avantpassats? Huummm... Així que voleu saber com feien foc els nostres avantpassats? Bé, bé... En primer lloc heu de pensar que no tenien llumins, ni encenedors, ni podien cuinar amb gas ni electricitat... els nostres avantpassats tenien una vida molt dura!

Mapping Mankind’s Trek – Ancient Coastlines and Land Bridges Over the last 150,000 years the world’s climate has switched constantly from warm interglacial to cold glacial conditions, marked by advances and retreats of ice sheets. From 75 – 60,000 years ago the climate was glacial and cold. The huge volume of water locked up in the ice caps of northern Europe and North America took the world’s sea levels to over 250 feet lower than today and made the climate very dry. Even in areas not directly affected by ice sheets, dry conditions saw forests give way to dry grassland, then to deserts. The effect on the natural resources available to the world’s very small modern human population, at that time mainly confined to their African homeland, was devastating and put their viability as a species on a knife edge.

DMNS-Ice Age in Depth What is an ice age? An ice age is a period of time—usually millions or tens of millions of years—when vast glaciers, called ice sheets, cover much of the Earth’s land surface. Several ice ages have occurred throughout our planet's history. The latest ice age began about 2.5 million years ago.

A late Pleistocene infantile skeleton from the Yamashita-cho Cave (Okinawa) by H. Suzuki (*) The possible connection of the Nansei Islands of Japan with the Asian continent in the Quaternary period was actually proved by the discovery of fossilized bones of extinct mammals such as deer and Naumann's elephant on two islands of the Ryukyu chain : Okinawa Honto (Nohara and Hasegawa, 1973) and Miyako Islands (Otuka, 1941).

The Origin of Us Who are we? Where did we come from? Why are we here? The age-old question of our origin has been baffling mankind for centuries. For most of our history, it was widely accepted that man had been created by an omnipresent, omnipotent, God or Gods. Most ancient texts such as the Bible, Torah and The Sumerian tablets seemed to all contain similar stories of such beings.
