What Did Early Humans Really Look Like?
Could You Hack Your Brain to Have Unlimited Senses?
This week on TestTube Plus, Trace explores human evolution. In the first episode, he looked back on the evolution of our species and how we became human, then he discussed how race fits into all of this, why Europeans and Asians evolved differently. In this final episode of the series, Trace wonders where evolution might be taking us, but first, he tells the amazing story of the Ötzi Ice Man and why he's so important to anthropology.
The so-called "Ötzi Ice Man" was a well-preserved human discovered in ice the Ötziak Alps in Italy in 1991 (hence his name). He lived 5,300 years ago, and he's the oldest known naturally preserved human ever discovered. Shortly after he died at age 45, his body was covered in ice: he was so well preserved that anthropologists have been able to re-create what his life was like down to what his last meals were (deer meat and herb bread).
TestTube Plus is built for enthusiastic science fans seeking out comprehensive conversations on the geeky topics they love. Host Trace Dominguez digs beyond the usual scope to deliver details, developments and opinions on advanced topics like genetics, AI, and Mars exploration. TestTube Plus will also be available as a podcast-stay tuned for more info!
How Many People Can Earth Support? (Live Science)
"The late-18th century philosopher Thomas Malthus wrote these ominous words in an essay on what he saw as the dire future of humanity. Humans' unquenchable urge to reproduce, Malthus argued, would ultimately lead us to overpopulate the planet, eat up all its resources and die in a mass famine."
No, this is not what our stupid faces will look like in 100,000 years (i09)
"An artist has partnered with a computational geneticist to illustrate what our faces might look like in the far future. Apparently we're all going to become anime characters."
No, Humans Have Not Stopped Evolving (Scientific American)
"Many people argue that our technological advancement-our ability to defy and control nature-has made humans exempt from natural selection and that human evolution has effectively ceased. There is no "survival of the fittest," the argument goes, if just about everyone survives into old age. This notion is more than just a stray thought in the public consciousness."
