Vertebrates exhibit extensive variation in relative brain size. It has long been assumed that
this variation is the product of ecologically driven natural selection. Yet, despite more than …

The external environment influences brain cell proliferation, and this might contribute to
brain plasticity underlying adaptive behavioural changes. Additionally, internal genetic …

The extent to which the evolution of a larger brain is adaptive remains controversial.
Trinidadian killifish (Anablepsoides hartii) are found in sites that differ in predation intensity; …

Brain size, brain architecture, and eye size vary extensively in vertebrates. However, the
extent to which the evolution of these components is intricately connected remains unclear …

Natural selection is often invoked to explain differences in brain size among vertebrates.
However, the particular agents of selection that shape brain size variation remain obscure …

There is remarkable diversity in brain size among vertebrates, but surprisingly little is known
about how ecological species interactions impact the evolution of brain size. Using guppies …

The high energetic demands associated with the vertebrate brain are proposed to result in a
trade-off between the pace of life-history and relative brain size. However, because both life …

Mechanisms that generate brain size variation and the consequences of such variation on
ecological performance are poorly understood in most natural animal populations. We use a …

The astonishing diversity of brain sizes observed across the animal kingdom is typically
explained in the context of trade‐offs: the benefits of a larger brain, such as enhanced …

The brain is a plastic organ, and so intraspecific studies that compare results obtained from
wild individuals with those from common‐garden experiments are crucial for studies aiming …
