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.
One of the important goal for developmental biologists is to understand how humans develop from a single celled embryo to highly complex multi celled adult and also to find cures to different diseases we encounter during our life span.This is all possible when one can understand the mechanisms underlying various aspects of …

It was always thought ( based on previous research ) that modern humans originated in Eastern Africa, but according to new research published in latest issue of PNAS suggests south African origin for modern Humans.
The work led by Brenna M Henn presents data for more than 580,000 SNPs for several hunter-gatherer populations: the Hadza and Sandawe of Tanzania, and the â‰ Khomani Bushmen of South Africa, including speakers of the nearly extinct N|u language. (122)

Paleontologists led by Jianni Liu discovered a new animal ( which they describe as Walking cactus) during a 2006 excavation in southwestern China’s Yunnan Province. “Diania cactiformis – Walking cactus” was a 6cm long spiny animal lived during Cambrian age had a worm-like body with ten pairs of armored and likely jointed legs, resembling a cactus plant. The authors published their detail findings related to Diania cactiformis in recent issue of Nature journal.
This animal , a member of Lobopodia, a now-extinct group of animals resembling worms with legs, which may …

Node is a new community site for all the developmental biologists, where one can share their views on different aspects of developmental biologists, to debate and discuss relevant topics, or just to see whatâ€™s new from the field of developmental biology. The Node was launched in June 2010 by Development, a leading research journal in the field of developmental biology, and its publisher, The Company of Biologists. (583)

After working with Drosophila melanogaster for nearly about 10 years , I decided to work with another insect model organism for my post doc, which will help me to gain more insights into evo devo among Insects. Tribolium Castaneum also known as “Red Flour beetle” happens to be most famous insect model organism after fruit fly Drosophila. All the details related to insect development mostly come from the studies on Drosophila and many believe it to be universal and similar mechanisms might be taking place in other insect orders. (208)
