Uncommon Descent Serving The Intelligent Design Community

Human origins upended once again


We humans must have originated in some kind of a cement mixer, to judge from recent reports.

Making stone tools (Oldowan technology) is believed to have started in East Africa 2.6 million years ago and spread from there. But archaeologists recently found stone tools and butchered animals on a high plateau in Algeria:

The newly discovered limestone and flint tools are about 2.4 million years old — almost the same age as the oldest known such tools, which were found in Gona, Ethiopia, and are 2.6 million years old.

The discovery means that hominins were present in the Mediterranean fringe of North Africa around 600,000 years earlier than previously thought. Aisling Irwin, “Algeria fossils cast doubt on East Africa as sole origin of stone tools” at Nature


Abstract: East Africa has provided the earliest known evidence for Oldowan stone artifacts and hominin induced stone tool cutmarks dated to ~2.6 million years ago (Ma). The ~1.8 Ma stone artifacts from Ain Hanech (Algeria) were considered to represent the oldest archaeological materials in North Africa. Here we report older stone artifacts and cutmarked bones excavated from two nearby deposits at Ain Boucherit estimated to ~ 1.9 Ma, and the older to ~2.4 Ma. Hence, the Ain Boucherit evidence shows that ancestral hominins inhabited the Mediterranean fringe in Northern Africa much earlier than previously thought. The evidence strongly argues for early dispersal of stone tool manufacture and use from East Africa, or a possible multiple origin scenario of stone technology in both East and North Africa.

From others: It’s not clear what human group created the tools. No human bones were found at the site:

The animal bones also provided clues. Many of them came from species of extinct pigs, horses, and elephants that only lived within certain time frames, which the team checked against the dates from their magnetic calendar. This work, which took most of the decade to do, revealed that the two areas the team dug up were 1.92 million years old and 2.44 million years old.

The bones came from the  ancestors of crocodiles and hippopotamuses too:

One hypothesis is that early ancestors of modern day humans quickly carried stone tools with them out of East Africa and into other regions of the continent.

Another is a “multiple origin scenario,” in which early hominids made and used tools in both East and North Africa. 2.4-million-year-old tools found in Algeria could upend human origin story” at Agence France Presse

It reminds me a little of how every few years it's reported that there are more stars and galaxies than previously thought. After the first dozen times you'd think that they'd stop saying that and start saying, "Here's how many stars we can observe and extrapolate from what we observe. Beyond that we have absolutely no idea how many there are, because every time we build a bigger telescope we see more." OldAndrew
I think all this demonstrates is that the decay-based and strata-based dating methods are simply unreliable by far too many orders of magnitude to be taken seriously. Naturalism walks back it's errors by trumpeting new errors as discoveries. ScuzzaMan
and still wrong, so expect additional revisions, till they realize Moses reported it right to begin with in scriptural testimony. eventually the consensus science will catch up to what some of us already know is the strongest science refrerence RCCF framework for understanding science and Torah Discovery Chronology part of the Moshe Emes series for Torah and science alignment.
