Notion That Hox Genes Acquire New Roles Quickly, Without Compromising Old Ones
2014-03-19 21:55:48

Indiana University Bloomington It’s difficult to identify a single evolutionary novelty in the animal kingdom that has fascinated and intrigued mankind more than the lantern of the firefly. Yet to this day, nothing has been known about the genetic foundation for the formation and evolution of this luminescent structure. But now, new work from a former Indiana University Bloomington graduate student and his IU Ph.D. advisor offers for the first time a characterization of the...

Sea Anemone genetics
2014-03-18 13:58:44

Lee Rannals for redOrbit.com - Your Universe Online Researchers lead by evolutionary and developmental biologist Ulrich Technau at the University of Vienna say that a sea anemone has a genomic landscape that is half animal, half plant. Developmental biologists found that the genetic landscape of sea anemones features complex regulatory elements similar to that of fruit flies or other animal model systems. However, they also discovered that sea anemones are more similar to plants rather...

A team of researchers at the University of Massachusetts Amherst is proposing a new investigative roadmap for the field of evolutionary developmental biology, or “evo devo,” to better understand how innovation at the genetic level can lead to ecological adaptations over time. Evo devo seeks to understand the specific genetic mechanisms underlying evolutionary change. Seven UMass Amherst authors, all biologists but with diverse research programs including evolutionary genetics,...

A Model For Development Built By Biologists

Caltech biologists create the first predictive computational model of gene networks that control the development of sea-urchin embryos As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts–muscles, bones, heart. In order for each cell to know what to do during development, it follows a genetic blueprint, which consists of complex webs of interacting genes called gene regulatory networks. Biologists at the California Institute...

Biologists have long assumed that all jawed vertebrates possess a full complement of nearly identical genes for critical aspects of their development. But a paper in the December 16 issue of Science with Benjamin King of the Mount Desert Island Biological Laboratory (MDIBL) as lead author shows that elasmobranchs, a subclass of cartilaginous fishes, lack a cluster of genes, HoxC, formerly thought to be essential for proper development. Hox genes dictate the proper patterning of tissues...

The development of identical egg laying organs of two nematode species is regulated by different signaling pathways Changes in a short protein domain can alter a whole signaling network involved in organ development"“ this is the key result of a comparative study of the development of the egg laying organ in two species of nematodes. However, the outward appearance of the organ remains the same in both species. The study provides support for the theory of developmental systems drift...

NEW ROCHELLE, N.Y., Jan. 5 /PRNewswire/ -- Theodosius Dobzhansky, the late great geneticist and evolutionary biologist, said it best: "Nothing in biology makes sense except in the light of evolution." This year marks the 200th birthday of Charles Darwin (February 12, 1809) and the 150th anniversary of the publication of the Origin of Species, which laid out the theory of evolution by means of natural selection in exquisite detail. Universities, academic centers, and other scientific...
