'First of our kind' found in Morocco

The idea that modern people evolved in a single "cradle of humanity" in East Africa some 200,000 years ago is no longer tenable, new research suggests. 
Fossils of five early humans have been found in North Africa that show Homo Sapiens emerged at least 100,000 years earlier than previously recognised. 
It suggests that our species evolved all across the continent, the scientists involved say. 
Prof Hublin's excavation has further revealed that these ancient people had employed stone tools and had learned how to make and control fire. So, not only did they look like Homo Sapiens, they acted like them as well.
So,this prooves that the history that we know can change from a day to other with discoveries like this,and remember us that not all that we know can be 100% truth.

Antarctic ice crack takes major turn

The fissure, which threatens to spawn one of the biggest bergs ever seen, has dramatically changed direction.
The rift has propagated a further 16km, with a significant apparent right turn towards the end, moving the tip 13km from the ice edge.The fissure currently extends for about 200km in length, tracing the outline of a putative berg that covers some 5,000 square km , an area about a quarter of the size of Wales.
Were the shelf to collapse (and even if it did, it would still take many years to complete), it would continue a trend across the Antarctic Peninsula.
Summarizing, the antartida is breaking, it is melting and it seems that we continue to ignore it, we will see what happens, but it goes from bad to worse.
