Un nuevo estudio revela que los gigantes de África no se extinguieron más, simplemente dejaron de aparecer nuevas especies.

Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land-use transformation. These changes challenge how we assess, ...

Recent studies have highlighted evidence of human impact on landscapes dating back to the Late Pleistocene–long before the advent of agriculture. Quantifying the extent of vegetation transformations b...

Across many scales of life, the rate of evolutionary change is often accelerated at the time when one lineage splits into two. The emergence of novel protein function can be facilitated by gene duplication (neofunctionalization); rapid morphological ...

The emergence of multi-tonne herbivores is a recurrent aspect of the Cenozoic mammalian radiation. Several of these giants have vanished within the past 130,000 years, but the timing and macroevolutio...

Dinosaur acclimatization and the evolution of bird-like, independent thermoregulation are heavily debated. Chiarenza et al. quantify the evolution of dinosaur thermal strategies, showing trends toward...

We used the Iberian fossil records to reconstruct mammalian food webs throughout millions of years. We found that trophic networks became sparser and less connected towards the present and that a hig....

Fossil tooth data show decreases in the abundance and biomass of the largest mammals over the past 4 million years.

Differential survival of mammalian lineages explains the increase in body size in early megaherbivores.

Horses became ubiquitous elements of Cenozoic communities and reached high diversity in Neogene times. Most accounts of their diversification history have so far focused on the Early Miocene cladogene...

After the resource-use hypothesis, habitat fragmentation caused by climatic changes would affect particularly species inhabiting only one biome, which might suffer more both speciation and extinction...

The authors use model-based approaches to examine the entire fossil history of proboscideans, from their dispersal outside of Afro-Arabia in the Oligocene to late Miocene extirpations and Quaternary c...
