Fake news on Bigfoot - just look at the photo!

I couldn't help sharing this "article" with you, which supposedly shows a bigfoot in its phot. A hoax, no doubt. This kind of unprofessional articles harms the cause of those who try to be serious and scientific.

The image is so crude and the hoax is so evident, that it is embarrassing.

Denisovans, Inuit and Native Americans

An article, which you can read here Arctic Inuit, Native American cold adaptations may originate from extinct hominids from Dec. 2016, tells us something about the Inuit, Amerindians and Denisovans or some other now extinct archaic hominid... (the original paper is here).

Two genes, TBX15 and WARS2 seem to be critical in how the body deals with fat in cold climates to generat heat. The article points out the following:

" The Inuit DNA sequence in this region matches very well with the Denisovan genome, and it is highly differentiated from other present-day human sequences, though we can't discard the possibility that the variant was introduced from another archaic group whose genomes we haven't sampled yet," said Fernando Racimo, lead author of the study.
The authors found that the variant is present at low-to-intermediate frequencies throughout Eurasia, and at especially high frequencies in the Inuits and Native American populations, but almost absent in Africa. TBX15 is a gene known to affect the human body's response to cold, and is associated with a number of traits related to body fat distribution. The authors speculate that the archaic variant may have been beneficial to modern humans during their expansion throughout Siberia and across Beringia, into the Americas.

Allow me to suggest another option: the archaic variant evolved in Homo erectus in high latitude Asia, they had reached this part of the world at least 1 million years ago. They hunted big game (mammoths and hairy rhino lived there and did so for millions of years). What would stop them from following the heards into America? Thanks to this adaptation they could. And this is why, their descent, the Amerindians carry it. Later after Homo sapiens evolved in America, it back migrated into Siberia and Eurasia and reached -though diluted- Africa when it was peopled by modern H. sapiens from Asia and America.

This explains the cline from a peak in America to a low in Africa. As you moved into hotter regions it became less of an advantadge (actualy a fatty layer in a hot climate is a disadvantage).

Early man in Northern Yukon 300,000 years ago

This paper dating back to the 1980s: Stratigraphic, Sedimentological and Faunal Evidence for the Occurrence of Pre-Sangamonian artifacts in Northern Yukon by Jopling, AV, WN Irving, and BF Beebe. 1981.Arctic 34 (1): 3-33, reports evidence of ancient human presence in Yukon - Alaska. An excerpt from the paper is very interesting:

"... It is interesting that these early human inhabitants predate the extinction in Europe and western Asia of most or all populations of Homo sapiens neandertalensis. Indeed, if Unit 1 is of Illinoian = Riss age, these artefacts probably are older than Mousterian cultures and Neandertal Man. Elsewhere, Irving (1978a, b) has commented on a plausible relationship of these early cultures to the Early Palaeolithic of the Far East, ar elationship anticipated by Chard (e.g. 1963) and more recently by Rouse (19801, although terminologies differ. Bryan (1978) has published an unusual human calotte from Brazil which beckons renewed attention in this connection. In a recent announcement Chia et al. (1979) describe a large collection of vertebrate fossils and stone artefacts found near Hsuchiayao in Yangkao County, Shansi, China. They attribute the entire collection to an age comparable with that of the Riss (Illinoian) glaciation. The associated human skeletal remains are said to be intermediate between Homo erectus and Homo neandertalensis (sic). Elsewhere Medvedev (1979) appears to have documented the northward progress ofHomo sp. as far as the Aldan Plateau in Siberia, 200 000 or more years ago. We must now, therefore, entertain seriously the possibility that a variant of Homo erectus reached the Western Hemisphere, as recently suggested by Yoshizaki (pers. comm., 1981). If true, this must profoundly affect both studies of the origin of Homo sapiens and studies of New World populations..."

For map lovers, This map shows the site.

1981 was ages ago!!! I was in my 20s!!, the world was quite different, wasn't it? No internet, cellphones, WiFi, I was programming in Fortran in University! The so called good old days... like another life ago!

Into Africa, some proof on an Out Of America origin of modern Homo sapiens

Regarding my previous post where I mentioned a paper on the non-African origin of modern humans, I have come across another very interesting paper: "Explaining worldwide patterns of human genetic variation using a coalescent-based serial founder model of migration outward from Africa" by Michael DeGiorgio, Mattias Jakobsson and Noah A. Rosenberg (Proc Natl Acad Sci U S A. 2009 Sep 22; 106(38): 16057–16062. Published online 2009 Aug 17. doi: 10.1073/pnas.0903341106) which offers an interesting model which can explain the greater diversity of Africans and at the same time make them the "most recent" humans instead of the oldest ones.

The usual argument for an Out of Africa origin of Homo Sapiens is the higher diversity in Africa versus that of non-African populations. A typical example used as proof is the graph showing how Heterozygosity decreases with the distance to Africa (there are countless of these on the internet, with the Y axis showing Heterozygosity and the X axis showing the distance from Addis Abbaba), below is one of them:

A typical heterozygosity vs. distance to Ethiopia. From Fig. 2 in [1]

Notice the negative gradient of the graph (shown by the dashed line in the figure -Fig. B, on the right). Heterozygosity falls from left to right.

The paper by DeGiorgio, Jakobsson and Rosenberg which caught my attention explores a models to explain this fact. In doing so they analyze different alternatives. And the one they discard because it does not fit the current idea of an Out of Africa model, is precisely the one that explains the data, if you accept a non-African origin of mankind. Allow me to explain:

Archaic Persistence Model

The team developed this "archaic persistence model" in which an archaic population evolved-mutated and originates modern humans (Homo sapiens). And as this first original and most ancient Homo sapiens population expands outwards from its homeland, it spreads gradually forming colonies which move into a "collection of preexisting archaic populations". For instance Denisovans, Neanderthals or even surviving yet unknown Chinese hominds -or Homo erectus descendants...

In the words of the authors, this is what they observed as the populations moved away from the original nucleous, the first modern human population:

"Heterozygosity increases, LD decreases, and the ancestral allele frequency spectrum slope increases with increasing colony number. These results can be understood from the fact that in the long time since the initial divergence, the K archaic populations have enough time to develop distinctive localized variants. As the migration wave travels through them, it accumulates diversity, gathering new variants from each population through which it passes. Thus, heterozygosity increases with increasing colony number in the same way that it increases in the archaic admixture model at the population in which admixture occurs. The difference between models lies in the fact that in the archaic persistence model, archaic admixture occurs in every population, so that heterozygosity increases at each step rather than at a single location. This occurrence of archaic admixture at each step also explains the decrease in LD and increase in the slope of the ancestral allele frequency spectrum that occur at each step...

In other words they observed that if the original, the "first real" human group, was in Africa, as we moved further away from there we should find more heterozygosity, which we don't. Hence the model is wrong and despite having originated in Africa we did not go through this type of admixture.

But lets just look at this with a more open mind:

Turn it around!

However if the original home of modern humans (Homo sapiens) was in America and not Africa, then, as they migrated outwards from America, into Asia, Oceania, Europe and went through each of the archaic populations in the old world, adding diversity and finally reached Africa mixing with the archaics there, the heterozygosity would be lowest in America and grow towards Africa, which is exactly what their model finds and which coincides with the observed heterozygosity cline in modern humans.

So It all makes sense if you invert the origin of the first humans: form Africa, to America.

Below is the image showing how heterozygosity grows as you move away from the original H. sapiens population if you assume the Archaic Persistence Model, the authors discard it because the actual observed heterozygosity falls as you move away from Africa:

From Fig 6 in DeGiorgio, Jakobsson and Rosenberg, adapted by A. Whittall

Now let's turn this same figure around and the result is a graph with a negative gradient which is exactly the same as the first graph we used in this paper (the distance to A. Abbaba & heterozygosity):

Same figure as above but we change the location of the first modern humans

As an engineer, I sometimes get the feeling that Anthropology and those who study the origins of humanity are like the late 1800s Physicists who despite all the evidence kept on pushing the notion of ether or fiddle with the data to uphold classic mechanics. It took Einstein and Plank to change the paradigm with their Relativity and Quantum theories. Something similar took place in the 1500s, with Copernicus explaining with graceful simplicity the movement of the planets, doing away with the complex Ptolomean system. A shift in mindset is needed to look at the same data to find the necessary changes and to avoid adhering to theories that contradict that data.

An intersting paper on the NON AFRICAN orign of mankind

Seems it is an Out of Asia after all...

This is a very interesting -at least it goes against the grain of most orthodox papers, positing an out of Asia orign of mankind- paper: WORLD SCIENCE EN ROUTE FROM OUT-OF-AFRICA TO OUT-OF-AMERICA: FIRST STOP IS OUT-OF-ASIA.

By the way, Happy 2017!! I have the feeling that this year will bring us surprises galore, and not only from some Neanderthals (with my apologies to our great and dignified ancestors) who have recently taken up their lodging in Washington DC.

May reason, sensible discussion of ideas, open-mindedness and above all, Western values such as respect, freedom to dissent, freedom of religion, thought and above all, freedom of speech, prevail above any populist sleazy politicians and their demagoguery. On both sides of the Anglo-Saxon Atlantic (i.e. Brexit supporters). Respect, chivalry and rationality must prevail over bigotry, prejudice and Medieval witch-hunting. Racism belongs with the 1940s fascists, not in the XXIst century.

And if you post any insidious comments I will publish them even if I disagree -of course-, no foul language please.
