early human agriculture may have changed the CO2 profile just enough to already have had a significant effect.

The site was of particular interest to population geneticist Andrea Manica of the University of Cambridge in the United Kingdom because the skeletons of five
humans were found with pottery, harpoons, and the remnants of nets and mats woven from twisted blades of wild sedge grass — which some (but not all) researchers consider a rudimentary form of
early agriculture.
In landscapes that are highly fragmented from
human activity like development and
agriculture, the end could come as
early as 2050, the researchers report today in Nature Climate Change.
But two new papers suggest that they were at home on both the land and the sea: Studies of ancient and modern
human DNA, including the first reported ancient DNA from
early Middle Eastern farmers, indicate that
agriculture spread to Europe via a coastal route, probably by farmers using boats to island hop across the Aegean and Mediterranean seas.
The paper identifies four major phases when
humans shaped the world around them with broad effects on natural ecosystems: global
human expansion during the Late Pleistocene; the Neolithic spread of
agriculture; the era of
humans colonising islands; and the emergence of
early urbanised societies and trade.

Climate change research here is in its
early stages, and scientists are still teasing out which changes in the high mountains are the result of climate change and which are more likely the result of other
human - caused changes, namely,
agriculture, ranching and mining.
A recent study suggested that land clearance and
early agriculture by
humans around that time could be the reason for the extra 40ppm in the atmosphere.

agriculture and that it was on the scrap heaps of

Before
agriculture was born (at most 10,000 years ago), all
humans naturally lost the ability to digest milk in
early childhood, after weaning from breast milk.
While this issue of diet and physical degeneration remains perennial throughout the history of
human agriculture, the problem stabilizes and begins to reverse as
early farming societies discovered the importance of using food preparation techniques such as fermentation, to increase digestibility and nutrient absorption.
The Paleo diet is a based on only consuming the types of foods eaten by
early humans before mass
agriculture, such as meats, vegetables, fruits and fish.
They didn't have any knowledge of nutrition, they weren't able to eat nutritious, calorie dense food whenever they wanted due to the absence of
agriculture, and their immune systems were likely weaker than ours (living together in large numbers placed enormous selective pressure on our
early agricultural ancestors to develop strong immune systems, keep in mind that
early human civilizations did not have indoor plumbing... so they were sometimes exposed to fecal matter both from fellow
humans and from livestock and they didn't have the kinds of disinfectants and anti-biotics we have today,) so for them to have serious health complications makes perfect sense, nature can be very harsh and doesn't care how long its been since your last meal or what your calorie and micro nutrient needs are... a lot of people died at very young ages back then simply because they got sick and didn't have proper medical treatment or due to malnutrition or starvation.
These types of plants, vegetables, and fruits may have been grown during
earlier periods in
human history, but are not used in modern large - scale

Dogs and canines were domesticated between 10,000 and 35,000 years ago through selective breeding, suggesting the
earliest dogs presumably arose once we,
humans, were still searching and gathering, way before the appearance of
agriculture.
Earlier in the year we pointed out that butterflies are being hit from two angles — not just a loss of habitat due to
human development and
agriculture, but also the effects of climate change.
