The nervous system—in particular, the brain and its cognitive abilities—is among humans'
most distinctive and impressive attributes. How the nervous system has changed in the …

Fossils and molecular data are two independent sources of information that should in
principle provide consistent inferences of when evolutionary lineages diverged. Here we …

To further our understanding of the genetic etiology of autism, we generated and analyzed
genome sequence data from 516 idiopathic autism families (2,064 individuals). This …

Although massively parallel sequencing has facilitated large-scale DNA sequencing,
comparisons among distantly related species rely upon small portions of the genome that …

The field of phylogenetics is entering a new era in which trees of historical relationships
between species are increasingly inferred from multilocus and genomic data. A major …

We analyzed the whole-genome sequences of a family of four, consisting of two siblings and
their parents. Family-based sequencing allowed us to delineate recombination sites …

Sexual and asexual reproduction are found throughout the plant and animal kingdoms.
Asexual reproduction has its advantages, chief among which is that it does not require the …

Abstract Language is a uniquely human trait likely to have been a prerequisite for the
development of human culture. The ability to develop articulate speech relies on …

Here we present a draft genome sequence of the common chimpanzee (Pan troglodytes).
Through comparison with the human genome, we have generated a largely complete …

The effective population sizes of ancestral as well as modern species are important
parameters in models of population genetics and human evolution. The commonly used …
