The evolution of some of the earliest complex animals on our planet may have been spurred on by other, simpler early animals. These simple marine animals first evolved around 560 million years ago and ...

To clarify the early evolutionary history of Cicadoidea fossils, the phylogenetic relationships between Mesozoic fossils and extant Cicadoidea, the macroevolution of body structure adaptations, and ...

Sponges are among Earth's most ancient animals, but exactly when they evolved has long puzzled scientists. Genetic ...

Recent study sheds new light on the enigmatic early evolution of snakes by examining an unexpected source: their brains. The results emphasize the significance of studying both the soft parts of ...

Prof. YUAN Xunlai from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences and his team have discovered a late Ediacaran crown-group sponge, Helicolocellus, from the ...

In a paper published in National Science Review, a Chinese team of scientists highlights the discovery of well-preserved blue-stain fungal hyphae within a Jurassic fossil wood from northeastern China, ...

Archosaurs have a nearly 250 million year record that originated shortly after the Permian-Triassic extinction event and is continued today by two extant clades, the crocodylians and the avians. The ...

Early angiosperms represent a pivotal chapter in plant evolution, marked by rapid diversification and profound ecological impact during the Early Cretaceous. These flowering plants, distinguished by ...

NASA scientists recently proposed a new explanation for the rise of oxygen in Earth’s early atmosphere – an event that may have jumpstarted the evolution of complex life. The idea is suggested in two ...

A fossil skull from a toothy early relative of today's birds shows a weirdly modern skull configuration, raising new questions about the early evolution of birds. When you purchase through links on ...

Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be. Chromosomes, the bundles of DNA that star in the mitotic ballet ...
