A colossal simulation of the past two million years of Earth’s climate provides evidence that temperature and other planetary conditions influenced early human migration — and possibly contributed to the emergence of the modern-day human species around 300,000 years ago.
The finding is one of many to come out of the largest model so far to investigate how changes in Earth’s movement have influenced climate and human evolution, published in Nature today. “This is another brick in the wall to support the role of climate in shaping human ancestry,” says Peter de Menocal, director of the Woods Hole Oceanographic Institution in Falmouth, Massachusetts.
Axel Timmermann, a climate physicist at Pusan National University in South Korea, and his colleagues ran a climate model on a supercomputer for six months to reconstruct how temperature and rainfall might have shaped what resources were available to humans over the past few million years. Specifically, the researchers examined how long-term fluctuations in climate brought about by Earth’s astronomical movement might have created the conditions to spur human evolution.
The model suggests that the distribution of H. heidelbergensis across the globe was possible because a more elliptical orbit created wetter climate conditions that allowed the species to migrate more widely. The simulation also showed that the most habitable regions, in terms of climate, shifted over time, and the fossil record tracked along with them.
Most researchers that spoke to Nature say that more evidence will be needed to prove that astronomical cycles influenced the trajectory of human ancestry. “If solving the mystery of climate change and human evolution could be dealt with in one paper, it would have been done 40 years ago,” Faith says.
Which is why Timmermann and his colleagues are planning to run even larger models, including ones that integrate genetic data.

I’m not sure I buy this.
But....record-breaking!...simulation!!. What do you need? Computer modeling?
So when it was cold, the Swedes, Norwegians and Finns stayed north and the other folks stayed in Africa where it was hot.
New Orthodoxy. Climate God. Climate religion.
All bs. And how does a simulation break a record?
Record-Breaking Simulation created by Insane Global Warming Fools
I think it’s just more outcome-based ‘science’.

Uh huh.
I remember when SA could actually be trusted.
Buying anything from Scientific UnAmerican is worthless
GIGO
That’s >25 years ago at this point. About the same time when NatGeo went bad.
Not even going to read it. GIGO
I thought there was an overlap about 20,000 years ago with Neanderthals and modern-day humans. Or, are they counting Neanderthals as modern-day humans?
Sure. Sumulations = evidence. Because there has never been any catastrophic events.
They can’t predict rain accurately 3 days out but claim they can accurately model climate “over the past few million years”
Pure bulllcrap. Not buying yet another lie.
There is way, WAY too much taxpayer dollars wasted on grants for climate related “research”. They can all go to hell.
Is this paper suggesting that life on earth adapts to changes in climate?
LOL. “Climate physicist.”
In other words, someone programmed a computer model to give them some output, and it did.
As someone who writes software for a living I guarantee its all fiction.
They instinctively knew that the mosquitos died off in the extreme cold and they could hunt caribou all winter for food without getting ate up by the skeeters. No need to migrate
