MIT CT Scans Reveal Early Copper Smelting and the Birth of Metallurgy in Ancient Iran
Uncovering an Ancient Breakthrough Around 5,000 years ago, communities in what is now Iran began extracting copper from rock through a process called smelting. This pivotal shift is believed to have laid the groundwork for metallurgy, a technology that would reshape human societies. New findings from MIT researchers, who employed computed tomography (CT) scans, illuminate…

Tongue-Bite Innovation Rewrites 310 Million-Year Fish Evolution
Unveiling the Tongue-Bite: A 310-Million-Year Innovation A recent study by a University of Michigan-led team reveals the earliest known tongue-like biting structure in an ancient fish. The species, Platysomus, lived about 310 million years ago during the Pennsylvanian period, a time when ray-finned fishes were experimenting with new feeding strategies. The discovery shows that these…

Tongue Bite Fossil Rewrites Fish Evolution: 310-Million-Year-Old Discovery
A fossil discovery from roughly 310 million years ago is reshaping how scientists understand the evolution of feeding in ray-finned fish. The fossilized remains of Platysomus, an early Pennsylvanian fish, show the first clear evidence of a tongue-like biting structure that used gill bones to crush and grind prey. This tiny but pivotal innovation demonstrates…
