This is the group sandbox page for Nikhil and Arjun for research on Limb Evolution.

Initial article assessments from Nvarade

Using information from these wikipedia pages will help assembling the Limb Evolution page, in addition to providing a link to those pages if a user needs more information.Tetrapod#From fins to feet, Polydactyly in early tetrapods, Fish fin#Evolution of fins, Evolution of mammals#Erect limbs, and Bat wing development#Comparisons to mouse limb developmentNvarade (talk) 05:26, 4 February 2014 (UTC)

Initial article assessment from Arjbajarj

The following book[[1]] starts as a good guide to starting an article that perhaps discusses more so the biology of the long major evolutionary adaptations made over time. It's from the book called "Fins into Limbs: Evolution, Development, and Transformation." Arjbajarj (talk) 03:01, 7 February 2014 (UTC)

Another article [[2]] called Developmental Basis for Limb Evolution that studies the pressures involved in creating evolutionary changes we have seen in the past and are seeing now. Arjbajarj (talk) 02:21, 7 February 2014 (UTC)

Article Draft

Erect Limbs

The preservation of a nearly 2 million year old Australopithecus Sediba from South Africa has contributed more knowledge of understanding human limb evolution. The analysis of Au. sediba's fossil lead researchers to hypothesis walked with fully extended lower limbs and walked with the distinct swing phase characteristic of bipedal walking. In addition, Au. sediba hand a more human-like abductor mechanism, which allows the pelvis to tilt whenever a step is taken therefore allowing the opposite foot to come forward, due to the fact that the pelvis had a more sagitally oriented ilia.Nvarade (talk) 01:36, 19 March 2014 (UTC)

Limb Evolution

There is no article on Limb Evolution, we can create a new page or we can add a section to article. The Limb Evolution section in article is poorly covered, we could add additional information given in our text book Developmental Biology Textbook, pages 512-513.Nvarade (talk) 07:22, 4 February 2014 (UTC)
