Scientists from France,Germany and Canada have recently put forward a new tree of life based on the most comprehensive phylogenomics study to date ,investigating 128 genes from a total of 55 species â€“ including nine poriferans, eight cnidarians, three ctenophores and the single known species of placozoans. This study was mainly done to overcome the confusions prevailing at the base of the tree of metazoans and also to establish relationships between some of these very early animal groups with a high degree of confidence.
This new study revives traditional views …

To be honest i never expected Hoxful Monsters would last for one long year, but i am happy that it did and i don’t have enough words to express what this day means to me. Exactly one year ago on 19th April 2008 i started my blog( my first blog post) , just as way to keep myself busy and make some good use of my time after lab work. Now a days as i am at the end of my final year of PhD , not getting enough time …
This post is dedicated to some important terms which we come across quite often while studying any article or chapter related to evolution
What is phylogeny?
The term phylogeny refers to the evolution or historical development of a plant or animal species, or even a human tribe or similar group. (or) Phylogeny represents the historical pattern of relationships among organisms which has resulted from the actions of many different evolutionary processes.
What is a phylogenetic tree?
A phylogenetic tree is a graphical representation of the evolutionary relationship between taxonomic groups.
(or) Cladograms or phylogenetic trees …

Bithorax complex in Drosophila consists of three homeodomain encoding proteins : Ultrabithorax (Ubx), abdominal-A (abd-A) and Abdominal-B (Abd-B). The function of these bithorax genes is to pattern entire abdomen ( A1-A9 segments ) and a part of third thoracic segment ,which happens to be their normal expression domain in embryos. These Hox proteins are expressed within specific parasegments (PS) , anatomical units that include the posterior portion of one segment and the anterior portion of the adjacent segment.
But the problem is that we have only three proteins and they need …
