More Evidence for Multiple Lines of Evolution in Our Genus Homo

Here is an interesting article from the New York Times website about the history of our Genus, Homo:

Recent fossil evidence shows that there was likely to be at least two other species of the Homo genus living at the same time as Homo erectus in east africa (about 2 million years ago). This is good evidence towards the view that the evolution of the homo genus is not so simple and straightforward as previously thought by some, but that there are multiple lines of evolution within our genus. I find it interesting how there is relatively little consensus between scientists as to our origins. It just goes to show that it is not easy to figure out what happened in the past.

Inspiring Mummification

I found this article on the National Geographic website:

http://news.nationalgeographic.com/news/2012/08/pictures/120813-mummies-chinchorro-proceedings-desert-driest-chile/#/death-cult-mummies-desert-shore_58198_600x450.jpg

 

The article consists of a collection of photographs of bodies preserved either by natural or artificial processes (the artificial process being called mummification). It is thought by some archaeologists that mummification done by ancient people was inspired by them finding naturally preserved bodies in dry environments such as the desert and trying to replicate the process. It is very interesting to me to see how ancient cultural activities that seem so strange to us had been motivated. I sometimes wonder if the ancient peoples ever considered that people in later centuries would find and study the things that they left behind.
