Eaten alive

Recent research from the University of Texas (1) sets the timing of the genius Homo excursion out of Africa to an earlier time and a harsher reality. They "mingled," with saber-toothed cats, wolves and hyenas and they ate only as many times as they were eaten. With a brain size smaller than half that of the modern human, their tools were primitive and their processes less compelling. They were effectively scavengers, with a badly designed and fragile infrastructure, that was no match to the mighty cats.

Human ego may have overlooked some information in the past as they had imagined their ancestors tall, dark and sturdy, leaving Africa, with a highly sophisticated technology, the hand ax. The UT team, based on a large sample over a 4 hectare area, argue this is not the case. The finding has implications, not only for history but also for biases that systematically creep into academic studies. In this contemporary world, where possibly half the population is likely unaware that its seven billion inhabitants are closely related, regardless of their outward appearances, scientists may need to do a better job in education. For without education, entire countries could walk back decades of progress and entire continents could move toward punishing tactical conflict. And, that would not be significantly different from what existed 1.8 million years ago, in architecture and context.

Humans have paid a big penalty because of their incessant curiosity, exploring foreign lands before they were possibly ready but what they brought to humanity is valuable knowledge. It will be a shame if modern humans lose it.
