Phylogenetic trees describe the pattern of descent amongst a group of species. With the
rapid accumulation of DNA sequence data, more and more phylogenies are being …

The Cambrian appearance of fossils representing diverse phyla has long inspired
hypotheses about possible genetic or environmental catalysts of early animal evolution …

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of
explanatory force unprecedented in our time—a landmark publication, both for its historical …

Rates of molecular evolution vary widely between lineages, but quantification of how rates
change has proven difficult. Recently proposed estimation procedures have mainly adopted …

One of the most brilliant scientists of our age gives us his definitive work: a synthesis of his
comprehensive vision of life. THE ANCESTOR'S TALE is a pilgrimage back through time; a …

Although evolutionary developmental biology is a new field, its origins lie in the last century;
the search for connections between embryonic development (ontogeny) and evolutionary …

Background The pattern and timing of the rise in complex multicellular life during Earth's
history has not been established. Great disparity persists between the pattern suggested by …

Oxygen has had extraordinary effects on life. Three hundred million years ago, in
Carboniferous times, dragonflies grew as big as seagulls, with wingspans ofnearly a metre …

Comparisons between insular and continental radiations have been hindered by a lack of
reliable estimates of absolute diversification rates in island lineages. We took advantage of …

The use of nucleotide and amino acid sequences allows improved understanding of the
timing of evolutionary events of life on earth. Molecular estimates of divergence times are …
