Although the transition from Australopithecus to Homo is usually thought of as a momentous
transformation, the fossil record bearing on the origin and earliest evolution of Homo is …

The allometric relationship between brain and body size among vertebrates is often
considered a manifestation of evolutionary constraints. However, birds and mammals have …

The Modern Synthesis led to fundamental advances in understandings of human evolution.
For human palaeontology, a science that works from ancestral phenotypes (ie the fossil …

Abstract Models based on the Ornstein–Uhlenbeck process have become standard for the
comparative study of adaptation. have cast doubt on this practice by claiming statistical …

Increased brain size in humans and other primates is hypothesized to confer cognitive
benefits but brings costs associated with growing and maintaining energetically expensive …

Quantifying speciation times during human evolution is fundamental as it provides a
timescale to test for the correlation between key evolutionary transitions and extrinsic factors …

Both absolute and relative brain sizes vary greatly among and within the major vertebrate
lineages. Scientists have long debated how larger brains in primates and hominins translate …

Many comparative neurobiological studies seek to connect sensory or behavioural attributes
across taxa with differences in their brain composition. Recent studies in vertebrates suggest …

Premise Geophytes—plants that typically possess a bulb, corm, tuber, and/or rhizome—
have long captured the attention of hobbyists and researchers. However, despite the …

While the human brain is clearly large relative to body size, less is known about the timing of
brain and brain component expansion within primates and the relative magnitude of …
