Good article.
Convergent evolution among primates. This is the first time I've ever seen anyone bring up this possibility. Amazing stuff.
The idea that the Rift Valley of east Africa is where modern humans evolved is getting a strong challenge from Southern Europe. That makes sense since the environment was possibly so much more hospitable to primates in Southern Europe than in east Africa hundreds of thousands of years ago.

“The print morphology suggests that the trackmaker was a basal member of the clade Hominini (human ancestral tree), but as Crete is some distance outside the known geographical range of pre-Pleistocene (2.5 million to 11,700 years ago) hominins we must also entertain the possibility that they represent a hitherto unknown late Miocene primate that convergently evolved human-like foot anatomy.”
Put simply, the study argues there was another — previously unidentified — human-like creature walking the Earth long before we believed it was possible.

The footprints’ discovery also comes shortly after the fragmentary fossils of a 7.2 million-year-old primate Graecopithecus, discovered in Greece and Bulgaria, were reclassified as belonging to the human ancestral tree.

That's called SciFi. And the sequel, "Shipstar" shows the Ice Minds were the ones in charge. Not the BirdFolk.

the most amazing thing on earth to me is that our cousin species died off JUST 25,000 years ago. that's like 2 hours ago in world years.

Shipstar
Bought it as soon as I finished the first one. Those 2 books started my passion for science fiction. Have you read any of his other books? I know ring world is popular but it was written in the 70's and I don't know if the physics would be on point like it was in Bowl of Heaven and Shipstar.

H. Floresiensis, the Hobbit human from Indonesia, died out only 18,000 years ago. The timeline for humans and our cousin species gets updated constantly.
That there were so many other species of humans dazzles me. And we keep finding more. In 2012 H. naledi was discovered in South Africa. That species was apparently at a midpoint to becoming fully human. They seem to have been a very peaceful species who revered their dead.

I think the more that they learn about the America's, specifically South America, the farther and farther these dates are going to be pushed back.
The South American civilizations are ridiculously misunderstood. The most amazing thing I've ever read is that the entire Amazon River basin may have been PLANTED by humans. Like a big arse garden. And now it's considered the "lungs of the planet".

I do, too. The Bering land bridge has been coming and going for hundreds of thousands of years. Archaic humans have been migrating into Siberia over the same periods. It would seem logical to think that many species made it to northern Siberia and crossed the bridge into North America and then down to South America.
While we presently have evidence only for modern humans having done this within the past 13,000 years, I feel confident that discoveries will be made that other human species, perhaps even some pre-humans made the same journey.

Maybe it was the GDCK? Or Bigfoot. Im going with Bigfoot.
Posted on 9/7/17 at 10:20 am to Pavoloco83
Bigfoot is a cryptid, so that's out. The animal that smashed the mastodon bones for their marrow 130,000 years ago was of a species that no longer exists. Whether it was a hominin is not yet known. I'm hoping it was from another member of the order Carnivora.
GDCK? Reptiles have reptilian brains, so that's doubtful.

Yep, I just finished the Louis and Clark journals and they were often looking for Welsh Indians, even suspecting they found them a few times

Well there were several humanoid mammals walking biped around the globe. It would make sense evolution spawned them globally around the same time. It's highly unlikely bipeds came from one single region.

Can we finally stop using the term "Native Americans"?
Posted on 9/13/17 at 3:52 pm to SamuelClemens
I totally agree. Anyone born in America is a native. First Americans is more appropriate if a label is needed. Actually, their tribal names seem more honorable. Sioux, Apache, Cherokee, Navajo, Creek and the others denote ethnicity and don't need an umbrella term to distinguish them.

I'm a big believer in pre-Columbus exploration making it to North America too. Of course the Vikings, but Celtics, Polynesians, and east Asia were all here before CC.
How many were really "explorers" as we think of it and how many were blown off course by a storm and washed ashore in the Western Hemisphere? The castaways would have left traces of their presence but I don't think you get credit for discovery unless you make it home with a credible map.

It's said that 99% of all species that have ever lived have gone extinct. The vast majority of them have not been found in fossils so there could have been animals, or maybe even plants, that did employ intelligence to survive.
Logically this would have to be true if you believe in evolution and understand statistics and probability.
Because the probability of everything lining up for basic cellular life to even exist is almost statistically impossible. It's more improbable for advanced life to evolve. It's even more improbable for advanced life that achieves sentience to evolve.
All in all through millions of years logic would conclude there would be many failures of life during natures evolution. Meaning most species that evolved didn't possess the traits necessary for long term survival. Add in natural disasters that eventually will occur through time due to probability that wipe out most species alive regardless of their survival traits and very few if any of the species alive today existed in their same form millions of years ago.
At some point a disaster will occur and wipe out the world as we currently know it. Humans may survive, they may not. But it will ruin civilized and technological society. And over time it will rebuild. And tens of thousands of years from now advanced life will study our time as they find our remains and relics.

At this point in our existence, I'd say we could survive some disasters. Those we could probably survive:
Asteroid. With enough time to react, we could probably change its path to impact.
Pandemic. We have the technical know-how to identify almost any pathogen and to construct a vaccine or cure.
Overpopulation. Even if we experience a Malthusian Collapse, there should be enough survivors to start over. Of course, most other species, at least the large ones, will be gone.
Climate change. The pace of change will determine how many survive. How severe it will be is also a determinant. There's always Antarctica as a last resort.
Artificial intelligence. Doomsayers like Elon Musk fear the worst about AI but i think machines will ignore us for the most part, eliminating only those humans who try to stop their development.
Those we would definitely not survive:
Nearby gamma ray burst. Say goodbye to all but microbial life living deep within the earth's crust.
Nuclear war. A combination of world wide radiation and nuclear winter would kill all of us. Who would want to live in a post-nuclear war world anyway?
Vulcanism. Anything like the Siberian Traps happening again, which was the source of earth's worst extinction event, would kill 95% of all life, including every human.
Posted on 9/18/17 at 3:37 pm to Kentucker
Agree with your extinction events. Would we know that a gamma ray burst happened in our galaxy and be able to say that in say, a thousand years we are going to be hit and cleansed by gamma radiation?
Nuclear war would see a few hundred elitists and some survivalists survive until supplies ran out but there would never be an earth fit to return to if they ever tried to leave their bunkers.
Gamma ray bursts are scary as shite. Fortunately they happen in other galaxies but one will happen in the milky way and we have to pray it doesn't happen too close to the sol system. What is the leading theory on the cause of these things?
