Developmental biology is the branch of biological sciences that investigates the processes by which organisms grow, differentiate, and acquire their form from fertilization to adulthood and often through regeneration and aging. It integrates molecular genetics, cell biology, genomics, and systems biology to elucidate mechanisms such as cell fate specification, pattern formation, morphogenesis, and organogenesis. Developmental biology examines regulatory gene networks, signaling pathways (e.g., Wnt, Hedgehog, Notch, TGF-β), epigenetic modifications, and mechanical forces that coordinate spatial and temporal control of gene expression and cellular behavior, providing a framework for understanding congenital disorders, tissue regeneration, and evolutionary changes in body plans.
Many people recognize that gender—how a person identifies, presents themselves and is perceived—has nuances. Some people identify and present as women, others as men, and still others as nonbinary.

One of the most important milestones in the early life of an organism is when the embryo breaks symmetry and arranges itself to form the head (anterior) at one end and tail (posterior) at the other end. Scientists have used ...

For an animal to develop normally, cells must not only become the right types but also do so at the right time. In the worm C. elegans, the protein LIN28 has long been known as an important regulator of this timing: It keeps ...
