For years, scientists have debated whether humans or the climate have caused the population of large mammals to decline dramatically over the past several thousand years. A new study from Aarhus University confirms that climate cannot be the explanation.

About 100,000 years ago, the first modern humans migrated out of Africa in large numbers. They were eminent at adapting to new habitats, and they settled in virtually every kind of landscape—from deserts to jungles to the icy taiga in the far north.

Part of the success was human’s ability to hunt large animals. With clever hunting techniques and specially built weapons, they perfected the art of killing even the most dangerous mammals.

But unfortunately, the great success of our ancestors came at the expense of the other large mammals.

It is well-known that numerous large species went extinct during the time of worldwide colonization by modern humans. Now, new research from Aarhus University reveals that those large mammals that survived also experienced a dramatic decline.

    Until a people develop science its pretty silly to me to assign a value judgment to things like this. Invasive species wipe out other species all the time, and did so before humans to boot. Mitigating that is ideal, but you don’t even really conceive of a problem until you have a society which can conceive of the harms and alternatives anyway.

      Yeah i think you have a point but I also think humans were moral agents and ascribed value to each other and their environment long long before the advent of science

        Sure. But until a people can even know what the consequences of their actions are it’s a stretch to judge them harshly.

        In this particular case, humans weren’t really moral agents until much later.
