Identifying the Big Questions in paleontology: a community-driven project Open
Paleontology provides insights into the history of the planet, from the origins of life billions of years ago to the biotic changes of the Recent. The scope of paleontological research is as vast as it is varied, and the field is constantl…

Late Cenozoic Faunal and Ecological Change in Africa Open
Africa's fossil record of late Cenozoic mammals documents considerable ecological and evolutionary changes through time. Here, we synthesize those changes in the context of the mechanisms proposed to account for them, including bottom-up (…

Late quaternary biotic homogenization of North American mammalian faunas Open
Biotic homogenization—increasing similarity of species composition among ecological communities—has been linked to anthropogenic processes operating over the last century. Fossil evidence, however, suggests that humans have had impacts on …

Plio-Pleistocene environmental variability in Africa and its implications for mammalian evolution Open
Significance We have developed an Africa-wide synthesis of paleoenvironmental variability over the Plio-Pleistocene. We show that there is strong evidence for orbital forcing of variability during this time that is superimposed on a longer…

Global long-term stability of individual dietary specialization in herbivorous mammals Open
Dietary variation within species has important ecological and evolutionary implications. While theoreticians have debated the consequences of trait variance (including dietary specialization), empirical studies have yet to examine intraspe…

No sustained increase in zooarchaeological evidence for carnivory after the appearance of<i>Homo erectus</i> Open
Significance Many quintessential human traits (e.g., larger brains) first appear in Homo erectus . The evolution of these traits is commonly linked to a major dietary shift involving increased consumption of animal tissues. Early archaeolo…

Body mass‐related changes in mammal community assembly patterns during the late Quaternary of North America Open
The late Quaternary of North America was marked by prominent ecological changes, including the end‐Pleistocene megafaunal extinction, the spread of human settlements and the rise of agriculture. Here we examine the mechanistic reasons for …

Reply to Weihmann: Fifty gazelles do not equal an elephant, and other ecological misunderstandings Open
Weihmann’s (1) comment on our recent paper (2) presents a misunderstanding of the principles of large herbivore ecology and the African fossil record. We welcome this opportunity to correct certain misunderstandings, focusing here on the t…

Early hominins evolved within non-analog ecosystems Open
Significance Testing ecological hypotheses of human evolution requires an understanding of the ancient plant and animal communities within which our ancestors lived. Though present-day ecosystems provide the baseline for reconstructing the…

Reorganization of surviving mammal communities after the end-Pleistocene megafaunal extinction Open
Extinction leads to restructuring By most accounts, human activities are resulting in Earth's sixth major extinction event, and large-bodied mammals are among those at greatest risk. Loss of such vital ecosystem components can have substan…

Temporal evidence shows <i>Australopithecus sediba</i> is unlikely to be the ancestor of <i>Homo</i> Open
Analyzing their geological ages, we demonstrate it is unlikely that Australopithecus sediba is ancestral to Homo .

Pattern and process in hominin brain size evolution are scale-dependent Open
A large brain is a defining feature of modern humans, yet there is no consensus regarding the patterns, rates and processes involved in hominin brain size evolution. We use a reliable proxy for brain size in fossils, endocranial volume (EC…

Pleistocene footprints show intensive use of lake margin habitats by Homo erectus groups Open
Reconstructing hominin paleoecology is critical for understanding our ancestors’ diets, social organizations and interactions with other animals. Most paleoecological models lack fine-scale resolution due to fossil hominin scarcity and the…
