Milk Doing a Body Taller

Dear Media

new data does not alter the theory

it only impacts parts of the hypothesis

and re-orders what is known

science is that robust, it is completed in with new details

ability to exploit new food groups – milk with vitamin D in more northern climes

“This is exciting because we now have a proven resource that could finally bring definitive answers to fundamental questions about the early movements and conditions of human populations—and new information about the importance of vitamin D for modern populations,” says McMaster anthropologist Megan Brickley, lead author of the paper and Canada Research Chair in the Bioarchaeology of Human Disease.

on simple and visceral level, eh

these variations in a species, leads to sexual selection

    I dunno about pretty, but it has nutrition in it, which water does not

    There is so much hype, especially from the dairy industry, about drinking cow’s milk. Goat and sheep milk are more nutitrious and healthier overall. In addition, not all kids can consume dairy products. There are other foods where they can get many or all of the same benefits as milk or other dairy products.

    +lee baron animal milk is probably the same, while nut milks do not provide that level of nutrition, but this is not about corporate agendas, this is about species, niches and food sources. Science is a different thing than it’s capitalist misapplications

    This is what caught my eye from that article:

    The animal rights organization PETA has linked dairy milk to autism

    If you doubted it, PETA members are fucking retarded (they probably got that idea from some stupid playmate).

    I do not support PETA, I deem them a part of the problem, they support violence.

    Not all animal milk is the same. They each have different levels of amino acids and other nutrients, as well as different levels of digestability. Whether or not it’s about corporate agendas–and it often is when it comes to people’s health–is not what I was intending. I simply stated that there is alot of hype where the dairy industry is concerned, period.

Science – adjusting and adapting to new information, that increases our existing understanding

“It’s not just when these people died that matters, but where. Their presence in north Africa complicates what was once a tidy picture of humanity arising in the east of the continent. “What people, including myself, used to think was that there was a cradle of humankind in East Africa about 200,000 years ago, and all modern humans descend from that population,” says Philipp Gunz from the Max Planck Institute for Evolutionary Anthropology, who was involved in the new excavation. “The new finds indicate that Homo sapiens is much older and had already spread across all of Africa by 300,000 years ago. They really show that the African story of our species was more complex than what we used to think.” “

They mark the earliest fossilized remains of Homo sapiens ever found. Until now, that honor belonged to two Ethiopian fossils that are 160,000 and195,000 years old respectively. But the Jebel Irhoud bones, and the stone tools that were uncovered with them, are far older—around 315,000 years old, with a possible range of 280,000 to 350,000 years.

The Oldest Hominins Could Have Lived in Europe, Not Africa, Claims New Study
The recent African origin of modern humans is, in paleoanthropology, the dominant model of the geographic origin and early migration of anatomically modern humans.
According to this model, Homo Sapiens evolved in East Africa and then began to disperse throughout the world roughly 50,000 to 100,000 years ago. This discovery – 5 Modern Human skeletons that date to between 300,000 and 350,000 years old – breaks the scientific consensus on the theory that has existing since the mid-2000’s.

Homo Naledi and Our Distant Ancestors Roamed The Earth Together

When bones of a new human species were found deep in a South Africa cave a few years ago, they looked 2 million years old.

But scientists recently made a startling discovery — the bones were much younger, between 226,000 and 335,000 years old. That means the newly found species, dubbed Homo naledi, roamed the landscape at the same time as ancient humans.

After the groundbreaking discovery of the 5-foot-tall hominin with hands and feet similar to our own but a brain only one-third the size, explorers searched for more bones. Their search paid off. The new fossils come from at least two adults and a child, including one that is so remarkably complete it was dubbed “Neo.”

The discovery was announced Tuesday with the publication of a series of papers in the journal eLife.

“This is incredible. What we’re looking at with Neo is a skeleton as complete as Lucy, the most famous in the fossil record,” said University of Wisconsin-Madison anthropologist John Hawks, referring to the Australopithecus afarensis skeleton found in Ethiopia in 1974.

Hawks, an expert on early hominins, is the leader of the research team at the Rising Star cave system in South Africa and the lead author of the paper describing the new fossils. Neo’s skeleton has a complete collarbone and almost a complete femur, giving researchers important clues about its size and stature as well as its ability to walk and climb.

The shape of the vertebrae has been seen before only in Neanderthals. As Neo’s skull was reconstructed bit by bit like a jigsaw puzzle, the adult male’s jaw, teeth and eye sockets became visible.

“Like all fossils that are fragmented and broken, fitting them together and seeing the face for the first time and realizing you’re looking into a face that no one has seen since (Homo) naledi’s group was there, it’s so significant,” Hawks said in a phone interview from Madison.

In 2015, an international team that included Hawks and other UW researchers revealed the largest trove of fossilized bones and teeth found in Africa. The skeletons of the previously unknown human species had been found squirreled away in caves that were so difficult to reach, organizers sought skinny paleontologists, thin and nimble enough to squeeze into the chambers to perform the painstaking work.

The initial discovery of 1,550 specimens has risen to around 1,800 representing at least 18 individuals. Scientists didn’t know the age of the bones but through a variety of techniques they were surprised to learn Homo naledi traversed Earth relatively recently.

“We expected this should be in Chapter 4 (of hominin evolution) and we found them in Chapter 9. That is a real surprise,” Hawks said. “If you talk to experts in the field, they say this is the wrong time. They shouldn’t be there then.”

If modern man, Homo sapiens, dates back to roughly the last 200,000 years and Homo erectus, an extinct hominid that walked upright and had ape-like features, dates from between 1.9 million years and 140,000 years ago, Homo naledi fits somewhere within that timeline.

Whether Homo naledi mated with Homo erectus or Neanderthals and co-mingled genes and DNA is not yet known. So far scientists have not been able to extract DNA from Homo naledi bones.

“Based on its anatomy it looked like something 2 million years old. I conclude that it probably is something that branched from our lineage. It survived for most of those 2 million years alongside with humans much more like us,” Hawks said. “You may ask ‘why did we not see this before?’ I think the answer is we haven’t looked.”

The bones were dated by measuring the amount of uranium and thorium in calcite stone deposits found on top of the fossils, which were estimated at 226,000 years. Bits of Homo naledi teeth were also ground up to measure the electromagnetic fields since teeth are imprinted with a time signature from exposure to natural radiation.

As more bones are discovered in out-of-the-way locations in the cave system, it appears that Homo naledi used remote, dark places to cache their dead, a behavior that suggests the possibility of intelligence. There were no cut marks or signs of trauma on the bones that would suggest them falling into the cave. Though there’s been no evidence found of fire or torches Homo naledi might have used to find their way through the pitch dark passages in a cave system that stretches two kilometers, scientists ponder the reason why they went to such effort to store the bodies.

“I personally think we’re looking at evidence Homo naledi cared very deeply for members of their group and wanted to put these bodies where they would be protected,” Hawks said.

Hawks is returning to South Africa this month to spend the summer working at the Rising Star cave excavation. As teams of small anthropologists shimmy and crawl through tiny crevices into chambers looking for more fossils, Hawks will work outside.

“I don’t fit,” Hawks said. “It’s like working in space in the sense that I can’t go there and the only means I can have of understanding is with the science we’re using.”
