Half-a-billion-year-old fossils shed light animal evolution on Earth
Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on Earth. Paleontology News — ScienceDaily
Plate tectonics: Crustal recycling evolution
Nature Geoscience 10, 623 (2017). doi:10.1038/ngeo3015 Author: Valentina Magni The processes that form and recycle continental crust have changed through time. Numerical models reveal an evolution from extensive recycling on early Earth as the lower crust peeled away, to limited … Continue reading
When ancient fossil DNA isn’t available, ancient glycans may help trace human evolution
Researchers have discovered a new kind of glycan (sugar chain) that survives even in a 4-million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept … Continue reading

Evolution of ‘true frogs’ defies long-held expectations of science
New research shows, in contrast to expectations, ‘the rapid global range expansion of true frogs was not associated with increased net-diversification.’ Paleontology News — ScienceDaily
Newly Found 5.7 Million-year-old Human Footprints Fossil May Challenge History of Human Evolution
A trail of 5.7 million-year-old fossil footprints discovered in Crete could upend the widely accepted theories on early human evolution. The new prints have a distinctly human-like form, with a similar big toe to our own and a ‘ball’ in … Continue reading
Fossil of hairy, squirrel-sized creature sheds light on evolution of earliest mammals
It appears that a 165myr-old omnivore may have had an armadillo-like gait. A newly discovered fossil has revealed the evolutionary adaptations of a 165myr-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of … Continue reading

Fossil footprints challenge established theories of human evolution
Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test. The footprints are approximately 5.7 million years old and were made at a time when previous research puts our ancestors in Africa … Continue reading

Meadow of dancing brittle stars shows evolution at work
Newly-described fossil shows how brittle stars evolved in response to pressure from predators, and how an ‘evolutionary hangover’ managed to escape them. Paleontology News — ScienceDaily
