what does second base mean in dating - Dating morocco

The earliest fossil attributed to a modern form of Homo sapiens comes from eastern Africa and is approximately 195 thousand years old.

Then other dating methods were employed that gave a wide range of older dates.

Electron spin resonance dating gave an age of 90,000 to 190,000 years, coupled U-series dating gave an age of 160,000 years, and marine isotope stage dating gave an age of 337,000 to 374,000 years.

For this study, fossil bones of Homo sapiens found in Jebel Irhoud, Morocco, between 20, were combined with other fossil bones and stone tools that were found over a period of time going back to 1960.

For many years the fossils found at this Moroccan site were claimed to be about 40,000 years old.

About the only thing new in this study is the claim that humans have been around over a 100,000 years longer than was thought.

The fossils themselves are old discoveries that haven’t created much excitement until now.

In the meantime, to ensure continued support, we are displaying the site without styles and Java Script.

The timing and location of the emergence of our species and of associated behavioural changes are crucial for our understanding of human evolution.

All humans are the descendants of a created, fully human pair.

It’s not surprising then that fossil humans of any imagined age look fully human.

Most minerals have the ability to show TL where energy from radioactive decay in the vicinity of the minerals causes electrons to be trapped in their crystalline structures and later released as light.
