I ran across an interesting article this morning in New Scientists regarding sleep and sleep habits in the elderly. Turns out their sleep habits of going to bed early and getting up at the crack of dawn may be an adaptation for survival in the wild graciously handed down to us by our ancient human ancestors! Thank you very much H. erectus!!
A study of this phenomena focused on the Hadza people who live in the bushlands of Tanzania. The wild poses many dangers for these people especially while sleeping but NO ONE keeps watch at night! In fact there’s not need to because it seems that natural variation in sleep patterns among the tribesmen means that there is always someone alert enough to sound the alarm if need be.
Fifty years ago psychologist Dr Fredrick Snyder postulated that animals who live in groups stay vigilant during sleep with some sleeping and others acting as sentinels. This is known as the “Sentinel Hypothesis.” What Dr Snyder apparently didn’t realize is that his hypothesis may also apply to HUMANS! Continue Reading
A recent study earlier this month by the Max PLanck Institute for the Science of Human History reports that Neanderthals received a genetic contribution from Africa by hominins who were closely related to modern humans more than 220 kya. The study obtained mtDNA (inherited from our mothers) from the femur bone of a prehistoric European hominin in an effort to resolve what appears to be our complicated relationship with Neanderthals. The genetic data has now given us a timeline for a possible migration out of Africa that took place after Neanderthal ancestors arrived in Europe and suggests Neanderthals were more closely related to modern humans than any other hominin species. What this means is that there may have been a migration out of Africa of hominins 220 kya.
What the study suggest is that after the Neanderthals arrived in Europe there was another migration out of Africa and those people interbred with the Neanderthals in Europe leaving their genetic marker in the Neanderthals mtDNA and these hominins appear to be closely related to modern humans. In addition, although likely this took place 220 kya it could have taken place as far back as 470 kya and may NOT have been a one time event either! Continue Reading
It is believed that Neanderthals in the Altai Mountains (Denisova Cave) interbreed with Denisovans and a mystery species or as some call it a “ghost species” of hominin. There is also the enigma of Population Y which I’ve blogged about before. Now comes a new “ghost species.” In saliva samples researchers have found hints of a ghost species of archaic humans that may have passed on genetic material to ancestors of people living today in sub-Saharan Africa! And, this latest research adds evidence to a growing body of evidence that suggests interbreeding between different archaic human species was far more common than previously thought
It’s long been known that Neanderthals in the Altai Mountains interbred with the Denisovans and some “ghost species” of hominin but now this new evidence also suggests that humans in sub-Saharan Africa also interbred with archaic human species! It’s beginning to look like it was “sex with anything even remotely human!” was the call of the time!! We thought such interbreeding between human species was the exception but growing evidence is now suggesting just the opposite is true. In fact, it may have been the NORM rather than the exception!

There’s a new book out by Austin Ruse entitled “Fake Science: Exposing the Left’s skewed statistics, fuzzy facts, & dodgy data.” Ruse is an author and news contributor at Breitbart News. I love what Amazon says about the book and that is that you’ve think we were living in the golden age of science “but the truth is far more sinister.” You bet! It goes on to say we are living in “the age of the low information voter.” I guess that’s what’s wrong with American politics today? It also goes on to point out that in this age we are too easily led astray by “all-too-convincing false statistics and studies.” Ruse points to the so called “facts” used to advance political agendas and points out how POORLY those “facts” actually stand up to REAL science!
I’ve posted about this a couple of times on this blog because even in anthropology and archaeology we are seeing this fake science as we are in climate science as well. Global warming is a political agenda, not science, and that is why global warming scientist must fudge their statistics and skew them. And btw it is a Communist Leftist political agenda!
Ruse also does some work at the UN, poor soul. You might know that august body as the most corrupt crime syndicate on the planet! 🙂 Which it is!! Ruse told BN he runs into “fake science all the time” and in his articles he’s attempted to debunk a lot of it. He pointed out during the interview with BN that when the scientists in their white coats enter the room the rest of us are suppose to NOT question, sit down, and shut up. Continue Reading
H/T to JR Bentley for alerting us to this HIGHLY SIGNIFICANT discovery in Australia:
Archaeologists in Australia have discovered the oldest stone axes with a ground edge on the planet! This discovery is very important because it sets back Australia’s human history to 65,000 years! That’s about 18,000 years earlier than thought. Further this date directly challenges the OOA (Out of Africa/Replacement Theory) along with theorized migration timelines and human evolution!
The archaeological team was excavating artifacts at the rock shelter known as “Madjedbebe” near the Kakadu National Park which is located about 300 km east of Darwin. The Madjedbebe is a rock shelter that sits atop the base of the Amhem land escarpment on a sandy plain. A number of artifacts were discovered by the team including the world’s oldest ground-edge axe head made by grinding rather than flaking. Chris Clarkson of the University of Queensland heads the team and research. He told reporters, “The site contains the oldest ground -edge stone axe technology in the world, the oldest known seed grinding tools in Australia and evidence of finely made stone points which may have served as spear tips.”

There are in fact many scientists who believe Madjedbebe is home of the earliest evidence of humans in Australia. This discovery has “universal importance” for the human evolution and for Australia’s native people as well as for Continue Reading
I was reading about these fantastic cats earlier today and came across this on the blog here: https://rperon1017blog.wordpress.com/category/cave-lions/
These were really fascinating creatures. They were indigenous to North America during the Pleistocene and apparently genetic studies have shown that it was a sister species to the Eurasian cave lion. It was one of the largest cats to have ever lived and was even slightly larger that the cave lion that existed during the Middle Pleistocene and not only that but it was 25% larger than today’s African lion.
The skull of the American Lion was similar to that of a Jaguar. Some research has suggested it may be closer genetically to the tiger than to the lion family. The braincase is more like that found in tigers than in lions. More recent comparison studies have suggested it was a distinct species and not really a lion at all. However, genetic studies clearly show it is a sister species of the Eurasian lion. Continue Reading
Fossils are NOT dated directly. They are dated indirectly. They date the rocks, not the bones. Is it possible that the rocks are much older than the bones? If a human dies and his skeleton by chance becomes fossilized (or any part of it) it is highly probable that the rocks near the remains are much older than the bones.
So let’s say I am hiking in the wilderness and fall over dead near some rocks and I’m lucky enough to be buried by a landslide so that my remains become fossilized. Then 1 million years from now an archaeologists comes along and discovers my fossil remains and dates the rocks (because there is still no technique to date the bones) at 3 million years old he concludes that my fossil remains are 3 myr. BUT they aren’t 3 myr! My fossil remains are only 1 myr!!
However, I’m sure this future archaeologist would use more than one technique to date my fossil remains. He might use Relative Dating in which fossils and layers of rock are placed in order from older to younger. But, things usually aren’t that simple because even though theoretically these layers should be from older (at the bottom) to younger (at the top) things happen in nature and sometimes layers get all mixed up. So that might mean the layer in which my fossil remains are found is NOT the layer in which I actually died. And the layer may be 3 myr but I only died 1 mya. So does the future archaeologist date me at 3 myr or 1 myr? He’d have to go by the rock layers and conclude that I died 3 mya. Continue Reading
