big science news on the AI and hominid family tree front

Scientific stuff, religious stuff, and all of the shit we don't yet know about like spooky ghosts and bigfoot.

big science news on the AI and hominid family tree front

Artificial intelligence applied to the genome identifies an unknown human ancestor
Date:
January 16, 2019
Source:
Center for Genomic Regulation
Summary:
By combining deep learning algorithms and statistical methods, investigators have identified, in the genome of Asian individuals, the footprint of a new hominid who cross bred with its ancestors tens of thousands of years ago.

Deep learning: deciphering the keys to human evolution in ancient DNA

By combining deep learning algorithms and statistical methods, investigators from the Institute of Evolutionary Biology (IBE), the Centro Nacional de Análisis Genómico (CNAG-CRG) of the Centre for Genomic Regulation (CRG) and the Institute of Genomics at the University of Tartu have identified, in the genome of Asian individuals, the footprint of a new hominid who cross bred with its ancestors tens of thousands of years ago.

Modern human DNA computational analysis suggests that the extinct species was a hybrid of Neanderthals and Denisovans and cross bred with Out of Africa modern humans in Asia. This finding would explain that the hybrid found this summer in the caves of Denisova -- the offspring of a Neanderthal mother and a Denisovan father -- was not an isolated case, but rather was part of a more general introgression process.

The study, published in Nature Communications, uses deep learning for the first time ever to account for human evolution, paving the way for the application of this technology in other questions in biology, genomics and evolution.

Humans had descendants with an species that is unknown to us

One of the ways of distinguishing between two species is that while both of them may cross breed, they do not generally produce fertile descendants. However, this concept is much more complex when extinct species are involved. In fact, the story told by current human DNA blurs the lines of these limits, preserving fragments of hominids from other species, such as the Neanderthals and the Denisovans, who coexisted with modern humans more than 40,000 years ago in Eurasia.

i'll use this thread to post sciencedaily.com stories from time to time because it looks like it won't disappear into ab*e's ethernet. feel free to comment on any of the articles as this thread goes forward.


Planetary collision that formed the moon made life possible on Earth
Study: Planetary delivery explains enigmatic features of Earth's carbon and nitrogen
Date:
January 23, 2019
Source:
Rice University
Summary:
Most of Earth's life-essential elements probably arrived with the planetary collision that produced the moon. Petrologists now conclude Earth most likely received the bulk of its carbon, nitrogen and other life-essential volatile elements from a collision with a Mars-sized planet more than 4.4 billion years ago.

Most of Earth's essential elements for life -- including most of the carbon and nitrogen in you -- probably came from another planet.

Birth of massive black holes in the early universe
Date:
January 23, 2019
Source:
Georgia Institute of Technology
Summary:
The light released from around the first massive black holes in the universe is so intense that it is able to reach telescopes across the entire expanse of the universe. Incredibly, the light from the most distant black holes (or quasars) has been traveling to us for more than 13 billion light years. However, we do not know how these monster black holes formed.

Do you think the alien version of a "Wisconsinite" stopped by our planet to fuck an animal, and accidentally created intelligent life on this planet?

I don't think this really surprises anyone. We know there was cross species intercourse between Neanderthals and Humans.
Why would there not be cross species intercourse between Neanderthals and Denisovans or Denisovans and Humans or all three?
It's been 32 years since one of MN's four major sports teams has been to the Championship/Superbowl.
Every single year is failure until we win one. 4 teams, 32 years. That's roughly 128 consecutive failed seasons.
