Evolution is eminent for all living organisms which determines how the organism will change and adapt to ever changing external environment. This provides divergence different species helps in creation of new ones. The that we see at present have evolved from one or other ancestor. study was held Rabi 2021 decipher evolutionary relationships between members Fabaceae. Phylogenetic analysis TFL s...

There is a well-established allometric relationship between brain and body mass in mammals. Deviation of relatively increased brain size from this pattern appears to coincide with enhanced cognitive abilities. To examine whether there is a phylogenetic structure to such episodes of changes in encephaliazation across mammals we used phylogenetic techniques to analyze brain mass, body mass, and e...

The phylogenetic relationship of human and apes are reviewed. The history of molecular phylogenetic studies in this field is then discussed, as is the role of natural selection at the molecular level. It is argued that approximately 10,000 genetic changes are responsible for creating human specific phenotypes. A genome-wide comparison is necessary to decipher those changes.

Common and dwarf bunt of wheat are recognized as being caused by three closely related species, Tilletia caries and T. laevis as common bunt, and T. controversa as dwarf bunt. The morphological characteristics of two species including T. controversa and T. caries were studied from wheat grown in two provinces of Iran, Lorestan and Chaharmahal–o-Bakhtiari duri...

Phytoplankton cells and resting cysts of the species Scrippsiella trochoidea are regular and dominant components of the dinoflagellate flora of coastal marine waters and sediments around the world. This species is a common harmful bloom forming species in coastal waters. In this study, for the first time cyst of S. trochoidea were isolated from the sediments of southeast coast of Iran. Five str...

Phylogenetic diversity (PD) has been successfully used as a complement to classical measures of biological diversity such as species richness or functional diversity. By considering the phylogenetic history of species, PD broadly summarizes the trait space within a community. This covers amongst others complex physiological or biochemical traits that are often not considered in estimates of fun...
