Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
Anatomical modernity. Bones of primitive Homo sapiens first appear 300,000 years ago in Africa, with brains as large or larger than ours. They're followed by anatomically modern Homo sapiens atleast 200,000 years ago, and brain shape became essentially modern by at least 100,000 years ago. ...
What are the differences between the male and the female digestive system? What are the functions of a flat bone? What are some of the defining physical features that set modern humans, Homo sapiens, apart from other hominids to make a ...
tive evidence we have is the shape of the vocal tract (the mouth, tongue, and throat): Until anatomically modern humans, about 100,000 years ago, the shape of hominid vocal tracts didn't permit the modern range of speech sounds. But that doesn't mean that language necessarily began then....
"We had insects 400 million years ago, dinosaurs 300 million years ago and flowering plants 130 million years ago," lead researcher Andrew Rushby, of the University of East Anglia in the United Kingdom, said in a statement."Anatomically modern humans have only been around for the last 200,...
Coinciding with the replacement ofNeanderthal Manby anatomically modern humans such asCro-Magnon Man, from 40,000 BCE onwards, art blossoms throughout Europe. The earliest lifelike sculptures are the Paleolithicivory carvings of the Swabian Jura- featuring birds, animals, and therianthropic figures,...
Even something as universally accepted as language was once a novelty, and while anatomically complete ancient humans were living their happy and fulfilled lives, few of them would have imagined that their intuitive yawps and grunts could be refined into implements of data retention. When formal ...
My current Intel Core I5 CPU 650 3.20 GHz 3.19 GHz computer, with 8G of RAM, 500G and 150G hard drives, operates on the same principles as my old Model III. The only substantial differences are a faster processor and, more importantly, vastly more RAM and memory. Now consider the rat,...
When growing asparagus, you can start from seed or one to two years old roots. Don’t worry;it is very easy to grow and maintain. It just needs regular watering while they are young. Once you give this vegetable a good start when you first plant them, the chances of having problems ...
esophagus. It relies on a thin catheter with a pH sensor at one end and a recording device on the other. The catheter is placed through the nose and guided into the esophagus so that it sits above thelower esophageal sphincter (LES). Anatomically, the LES separates the esophagus from the...
