But in recent years, a torrent of exciting fossil and DNA discoveries across Asia has forced a radical rethink of our family saga.
This week, prepare to have your mind blown by another tantalizing fossil find from the region that reveals just how sophisticated and knowledgeable our ancient ancestors really were.
In a remote cave on Borneo, Indonesia, archaeologists have made a discovery that upends our understanding of the Stone Age: an amputee who lived 31,000 years ago.
Only a century ago, most people who underwent amputation would have died — either from blood loss and shock or from subsequent infection.
Not only was this Stone Age surgery successful, but the amputee lived for another six to nine years, ultimately dying of natural causes before being delicately buried by caregivers, according to research.
Trailblazers
Scientists at the University of Cambridge in the United Kingdom have created synthetic mouse embryos in a lab dish — an exciting advance that ultimately could lead to new fertility treatments.
By observing the embryos at this stage of life in a lab instead of a uterus, the scientists got a better view into the mystifying process to learn why a pregnancy might fail and how to prevent this loss.
They hope to move from mouse embryos to creating models of natural human pregnancies — many of which fail in the early stages.
Fantastic creatures
The earliest mammal known to science, Brasilodon quadrangularis, was a shrew-like creature. It skittered at the feet of the first dinosaurs 225 million years ago.
In a case of mistaken identity, researchers previously thought the small animal was a reptile.
The discovery will help paleontologists better understand the evolution of modern mammals.
Defying gravity
What’s going on with NASA’s Artemis I mission after two failed attempts to launch its mega moon rocket?
The space agency has delayed a third try until September 23 or September 27 — or perhaps even longer still as engineers find a way to fix a hydrogen fuel leak.
Complicating matters is the changeable Florida weather, with hurricane season in full swing, and existing commitments: NASA expects to launch the Crew-5 mission, which will carry a fresh team of astronauts to the International Space Station aboard a SpaceX rocket, on October 3.
For now, the moon rocket remains on the launchpad while engineers replace the seal on an interface between the liquid hydrogen feed line and the launcher.
Mission critical
The Thwaites Glacier, located in West Antarctica and sometimes called the “doomsday glacier,” has for decades concerned scientists, who fear the extreme sea level rise that would accompany its potential demise.
Geophysicists have mapped the Florida-size glacier’s historical retreat, hoping to learn from its past what will likely happen in the future.
The research team found that at some point in the past two centuries, the base of the glacier dislodged from the seabed and retreated at twice the rate that scientists have observed in the past decade or so.
