Area of Science:

  • Evolutionary Biology
  • Developmental Biology
  • Paleontology

Background:

  • The fossil record reveals significant morphological changes and novel features in the evolution of complex life.
  • Evolutionary change is driven by modifications in developmental processes, not direct adult-to-adult transformations.

Approach:

  • Integrates principles from developmental biology and evolutionary science.
  • Examines how developmental processes influence and constrain evolutionary trajectories.

Key Points:

  • Developmental processes are central to generating evolutionary novelty.
  • Understanding the evolution of development is essential for a complete picture of evolution.
  • A synthesis between developmental biology and evolution is currently underway.

Conclusions:

  • Evolutionary history is shaped by the evolution of developmental mechanisms.
  • Future research will benefit from an integrated approach to development and evolution.
