Homo erectus, one of our genetic ancestors, may have died out due to laziness and a changing climate. Researchers from @ouranu found that a settlement of Homo Erectus in the Arabian Peninsula was using low quality stone for tools, even though there was high quality stone only a short walk away. So while Homo Sapiens and Neanderthals would traverse large distances to find the best possible resources, Homo Erectus preferred picking up whatever was near their camp. This proved fatal though, as a changing climate in the Arabian Peninsula eventually dried up the rivers and Homo Erectus was left without water. Their laziness meant that they hadn’t learned the skills and foresight to look for other resources and ultimately died out. Homo Erectus are an example of what happens when nothing is done in the face of climate change. Will humans have the same fate?
