Summary

Evolutionary developmental biology (EDB) and developmental systems theory (DST) are synthesizing previously dispersed biological programs. This review explores DST and EDB, their relation to epigenetics, and their impact on biological theory and practice.

Area of Science:

  • Integrative biology, focusing on the intersection of evolutionary biology, developmental biology, and epigenetics.

Background:

  • Historically, developmental and evolutionary biology have been relatively isolated fields.
  • Previous attempts to reconcile development and heredity were not broadly successful.
  • Recent years have seen a resurgence and synthesis of integrating programs in biology.

Purpose of the Study:

  • To provide an overview of developmental systems theory (DST) and evolutionary developmental biology (EDB).
  • To summarize the key tenets of DST and EDB.
  • To examine the relationship between DST, EDB, and the study of epigenetics.
  • To survey the past, present, and future impact of DST and EDB on biological theory and practice.

Main Methods:

  • Review and synthesis of existing literature on developmental systems theory (DST) and evolutionary developmental biology (EDB).

Related Experiment Videos

  • Comparative analysis of the core principles and approaches of DST and EDB.
  • Examination of the connections between these theories and the field of epigenetics.

    • Main Results:

    • Evolutionary developmental biology (EDB) is a recognized and growing field.
    • Developmental systems theory (DST) remains largely unknown within the broader biological community.
    • Both EDB and DST offer valuable frameworks for understanding the interplay between development, heredity, and evolution.

    Conclusions:

    • The integration of developmental and evolutionary perspectives, exemplified by EDB and DST, is crucial for advancing biological theory.
    • DST, despite its obscurity, offers unique insights that could benefit biological research.
    • Further exploration and integration of DST and EDB with epigenetics hold significant potential for future biological discoveries.
