This study is intended to review the cephalometric data pertaining to the diverse Indian populace through a systematic literature survey. To conduct a systematic review of literature, an electronic search was done on Medline, Embase, and Central databases. The available data were categorized based on the existing five geographic locations of the country (north, south, east, west, and central India) and analyzed.

Background And Aims: Quantifying niche similarity among closely related species offers myriad insights into evolutionary history and ecology. In this study, our aim was to explore the interplay of geographic and niche space for rare, endemic plant species and determine if endemic habitats were environmentally similar or unique.
Methods: We characterized the niche of all Leavenworthia species, a genus of rare plants endemic to rocky glades in the eastern United States, using WorldClim data, surface geology, elevation, and slope.
Genetic Assessment and Positioning of Algerian Barley Landraces with Respect to Landraces from the Middle East and Europe Using RAPD and SSR Markers.

Landraces are a critical genetic resource for resilience breeding, offering solutions to prepare agriculture for the challenges posed by climate change. Their efficient utilisation depends on understanding their history and genetic relationships. The current study investigates the phylogenetic relationships of barley landraces from Algeria, varieties from the Near and Middle East, traditional landraces, and modern cultivars from Europe.

The Indo-European languages are among the most widely spoken in the world, yet their early diversification remains contentious. It is widely accepted that the spread of this language family across Europe from the 5th millennium BP correlates with the expansion and diversification of steppe-related genetic ancestry from the onset of the Bronze Age. However, multiple steppe-derived populations co-existed in Europe during this period, and it remains unclear how these populations diverged and which provided the demographic channels for the ancestral forms of the Italic, Celtic, Greek, and Armenian languages.

Article Synopsis
- - North Africa has both fat-tailed and thin-tailed sheep breeds; the fat-tailed ones are better suited to dry environments.
- - A study analyzed genetic data from 462 sheep across 22 breeds to identify genomic regions under different selective pressures related to these traits.
- - Seven candidate regions on chromosomes, particularly around the BMP2 gene, were found to be under strong selection, linked to adaptations like fat storage and tolerance to harsh conditions.
