Charles Darwin’s work arose in an era where many were thinking about the source of nature’s variety.

Harvard Researchers show what drives functional diversity in the spines of mammal.

By re-barcoding the DNA of yeast, researchers were able to follow evolution for approximately 1,000 generations, finding surprises along the way.

Biology Professor Cassandra G. Extavour debunks old hypotheses about form and function on insect eggs using new big-data tool

With an innovative technique called anatomical network analysis, clear patterns emerge that help solve the puzzle of how fins became limbs 420 million years ago.

Based on an analysis of the genomes of more than a dozen flightless birds, including an extinct moa, a team led by Harvard researchers found that while different species show wide variety in the protein-coding portions of their genomes, they appear to turn to the same regulatory pathways when evolving flight loss.
