Tree of life brought to scale by Yale scientists

Examples of biological scaling are everywhere. The paw of a mouse is smaller than the human hand. Our own organs and limbs typically scale with our body size as we develop and grow.

Cell polarity: An aurora over the pole

Even before the fertilised egg or zygote can start dividing into daughter cells that form the future tissues and organs during the development of a multicellular organism, the symmetrical zygote needs to become asymmetrical ...

Evolution in the gut

Evolution and dietary habits interact and determine the composition of bacteria in the digestive tract. Many microorganisms in the intestine seem to have developed in sync with their host animals over millions of years.

How Capsella followed its lonely heart

The Brassicaceae plant family boasts a stunning diversity of fruit shapes. But even in this cosmopolitan company the heart-shaped seed pods of the Capsella genus stand out.

Revealing the mysteries of early development

Zebrafish embryos are transparent and develop outside the mother's body, enabling scientists to get a detailed view of early development. A research team led by Lila Solnica-Krezel, the Alan A. and Edith L. Wolff Distinguished ...

Developmental biology

Developmental biology is the study of the process by which organisms grow and develop. Modern developmental biology studies the genetic control of cell growth, differentiation and "morphogenesis," which is the process that gives rise to tissues, organs and anatomy. Developmental biology is that branch of life science, which deals with the study of the process by which organisms grow and develop.
