The presence of hominins our early human ancestors has been linked to regions with active tectonic and volcanic regions in Africa.
The researchers call for further study of ancient landscapes to support this theory though ancient conditions in active tectonic regions like the East African Rift can be difficult to reconstruct

Climatologists weren't aware of this until you mentioned it...Just because something is good for something at a particular level does NOT mean it's good at all levels
A corollary to this notion is that we are good at things we had to do back in the Pleistocene like keeping an eye out for cheaters in our small groups

Am I a climatologist? Nope. I'm an engineer. But I'm not putting forth new data.
I'm looking at the data climatologists have and saying: You've got nothing here.
Chances are if you're a climatologist you're going to be spouting the same biased data that every other climatologist is worried about.
There are no climatologists that have varying views on the issue because their entire goal in life is to prove that Climate Change is a thing
Saying 99%of climatologists agree climate change is occurring is like saying 99%of priests agree that god is omnipotent.
Just claims of climatologists are biased and lying to keep their jobs. Good science boys.@@Frosttty really dude.

This is less helpful in dating on more geological time scales but the various radiometric dating techniques used on those scales have other means of control
For this reason radiocarbon dating only works for organisms that obtain their carbon from air via carbon dioxide.
my guess as to the reason why is that carbon-14 dating is quite expensive and the purpose of the record is actually to help calibrate radiocarbon dating
so they didn't need to have annual resolution). Over the past 3000 years there have been 3 sharp spikes in carbon-14 levels over a short period of time.
Also@monkeybuttons while it's true that carbon-14 dating isn't perfectly precise this study was based on tree rings
and then build a calibration curve to make radiocarbon dating more accurate. Before 12000 years that record consists of data from marine sediments.

Work pioneered by Professor Sam Wasser at the University of Washington uses DNA profiling from seized ivory to trace it back to the geographical location within Africa from which the ivory was taken once roamed.
So some DNA types become much more common than others in defined geographical ranges which means that using similar DNA profiling techniques to those used in human forensic science the DNA from ivory provides a map leading back to the geographic area where those subpopulations with similar DNA profiles are found.

Now a new analysis combining climate agricultural and hydrological models finds that shortages of freshwater used for irrigation could double the detrimental effects of climate change on agriculture.
But hydrological models looking at the effect of warming climate on freshwater supplies project further agricultural losses due to the reversion of 20 to 60 million hectares of currently irrigated fields back to rain-fed crops.
Agricultural models and hydrological models both incorporate the influence of climate but are designed by different scientific communities for different purposes.
and other climate factors may alter the yield for various crops hydrological models seek to estimate water-related characteristics such as stream flow water availability and storm runoff.
But when Elliott and colleagues fed each type of model with the same climate model forecasts the models produced dramatically different predictions about the future demand for freshwater irrigationthe researchers discovered discrepancies in how hydrological models incorporate processes such as the carbon cycle
which a multi-model ensemble of hydrological models was compared to a multi-model ensemble of crop models Elliott said.
Several modeling groups have changed already the way that they are modeling the hydrological cycle with respect to crops because of the results of this paper.

An uninterrupted sequence of fossilized pollen from flowers begins in the Early Cretaceous approximately 140 million years ago
But the present study documents flowering plant-like pollen that is 100 million years older implying that flowering plants may have originated in the Early Triassic (between 252 to 247 million years ago) or even earlier.
Depending on dataset and method these estimates range from the Triassic to the Cretaceous. Molecular estimates typically need to be anchored in fossil evidence
That is why the present finding of flower-like pollen from the Triassic is significant says Prof.
In a previous study from 2004 Hochuli and Feist-Burkhardt documented different but clearly related flowering-plant-like pollen from the Middle Triassic in cores from the Barents sea south of Spitsbergen.
We believe that even highly cautious scientists will now be convinced that flowering plants evolved long before the Cretaceous say Hochuli.
In the middle Triassic both the Barents sea and Switzerland lay in the subtropics but the area of Switzerland was much drier than the region of the Barents sea.
