First Peoples of the Americas migrated from Asia thousands of years ago. Genetic similarities between Brazilians and Australasians today are attributed to a group that stayed behind and went south instead of crossing the land bridge into America.

#DNA #PeoplingOfTheNewWorld #FirstPeoples  
Scientists assume a wave of people from what's now Siberia crossed into North America via Alaska, maybe 23,000 years ago. Genetics support that, but may also suggest another wave from Australasia.

A mysterious culture emerges in the jungle. Can archaeologists uncover its secrets before it's too late?
A joint Honduran-American expedition has confirmed the presence of extensive pre-Columbian ruins in Mosquitia in eastern Honduras, a region rumored to contain ruins of a lost "White City" or "City of the Monkey God."

I'm retired and when presented with
nonsense and explanation I cannot
confirm please excuse me for not
listening.  Hands-on application.  Its
why I joined Michigan Technological University Department of Social Science Society for Industrial Archeology.
Confirmation took me to Detroit.  See
the Packard Plant to go figure.  That  
is more than my reader can expect.

More likely, the cave was a pilgrimage shrine where ritual sacrifices occurred.
Researchers are digging into a discovery that may alter the way we think about ancient Mayan culture.

Cenotes and caves were sacred water shrines for the ancient Maya.

#Maya   
 
Archaeologists are exploring a deep aquamarine pool in Belize, known to hold eerie ruins from a time when the ancient Maya turned to a "drought cult." What have they found?
As an ancient drought took hold, a water temple saw more offerings from desperate Maya, archaeologists report.

Wheeee! Robot Philae is the 1st to land on a comet!

#spaceexploration
 
A thistledown the size of a washing machine has fallen to a gentle crash-landing on a comet.

I feel proud just to be watching. Well done!

Comets are an original source of Earth's water. That wee lander is now in position, poised to re-write what we know about ourselves.

A dramatic visual to remind us to scale back our H2O consumption.

California's drought is not great.

This is Folsom Lake near Sacramento. It's sad because it's dry. If you're living in California, be aware of your water use. Also, don't water your lawn if you have one :)
