What they found was that the teeth to the hominids had an in-between amount of carbon-13,which meant not only they were eating fruits,they were eating a lot of grasses,or animals eating grasses.The lower carbon-13levels could also come from eating certain types of insects....

Watson, Crick, Franklin, and Wilkins knew the next step was to get the precise structure of DNA. It was February 1953 when a three-dimensional model that looked like a toy finally sat on Crick’s desk. It was the biggest advance since Mendel created the genetics paradigm; the Nobel Prize...

A blade could be made with all the right ingredients, but if the heating and cooling process in making it was out of synch, the whole thing would end badly. The blade would chip and shatter at first use, or be too soft to hold a functioning edge. Map that onto our developed sense ...
What was the first anthropoid? 2). Early anthropoids are best known from the phylogenetically diverse faunas of Afro-Arabia, especially those of the Fayum Depression in Egypt. The youngest of the Fayum primate-bearing deposits date to the Oligocene, ∼30 Ma, whereas the oldest arelate Eocen...
