Darwin's fear was unjustified: Writing evolutionary history by bridging the gaps a big issue

Science Daily - Paleontology - Mon, 08/26/2024 - 12:06
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil record has gaps and is incomplete, and we're missing data that we need to reconstruct evolutionary history. Now, a team of sedimentologists and stratigraphers examined how this incompleteness influences the reconstruction of evolutionary history. To their surprise, they found that the incompleteness itself is actually not such a big issue.

To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say

Science Daily - Paleontology - Wed, 08/21/2024 - 13:59
Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.

Fossil hotspots in Africa obscure a more complete picture of human evolution

Science Daily - Paleontology - Tue, 08/20/2024 - 11:45
A new study shows how the mismatch between where fossils are preserved and where humans likely lived may influence our understanding of early human evolution.

Scottish and Irish rocks confirmed as rare record of 'snowball Earth'

Science Daily - Paleontology - Fri, 08/16/2024 - 11:15
The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
