The current paper synthesizes theory and data from the field of life history (LH) evolution to
advance a new developmental theory of variation in human LH strategies. The theory posits …

This chapter provides an overview of life history theory (LHT). LHT conceptualizes specific
allocation tradeoffs in terms of three broad, fundamental trade‐offs: the present‐future …

Across taxa, both neural growth and cognitive function show considerable developmental
plasticity. Data from studies of decision making, learning, and discrimination demonstrate …

ABSTRACT The Social Intelligence Hypothesis (SIH) is one of the leading explanations for
the evolution of cognition. Since its inception a vast body of literature investigating the …

In the last few million years, the hominin brain more than tripled in size. Comparisons across
evolutionary lineages suggest that this expansion may be part of a broader trend toward …

Social mammals have three basic stages of postnatal development: infant, juvenile, and
adult. Some species also have a brief female post‐reproductive stage. The human life cycle …

A widespread and popular belief posits that humans possess a cognitive capacity that is
limited to kee** track of and maintaining stable relationships with approximately 150 …

Comparative studies have identified a wide range of behavioural and ecological correlates
of relative brain size, with results differing between taxonomic groups, and even within them …

Changes in gene expression levels determine differentiation of tissues involved in
development and are associated with functional decline in aging. Although development is …

Recent developmental studies demonstrate that early fossil hominins possessed shorter
growth periods than living humans, implying disparate life histories. Analyses of incremental …
