Study of evolutionary information of bacteria uncovered sudden changes in gene sequence of certain bacterial lineages
Researchers find that altered signalling patterns for survival by a fan-throated lizard species could be setting the stage for its evolution
The big, bright, green-coloured Andaman day gecko is a sight to behold; only that, you have to go all the way to the Andaman Islands to get a glimpse of it. Endemic to the islands, these geckos live in trees and are active during the day. Thanks to cash crops grown on these islands today, they can be found in plenty, feeding on bananas, coconuts and betel nuts. They belong to the genus called Phelsuma, believed to have evolved from Madagascar, an island about 6000 km away from the Andamans! A new study has traced their evolutionary history and has thrown some light on how they differ from the other geckos in the Andamans.
The Indian Society of Evolutionary Biologists (ISEB), an independent consortium of researchers and faculty working on evolutionary biology in India, is holding its first conference on the 24th and 25th of October, 2019, at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru. The two-day meeting is themed around ‘Celebrating Ecology and Evolution in India’. It is bringing together eminent researchers and students across the country, who are actively involved in research on evolutionary biology.
The blackbuck is an antelope species native to the Indian subcontinent. Although the term 'antelope' is loosely used to refer to many ruminating ungulates, the blackbuck is the only animal that belongs to the genus named Antilope. True antelopes belong to one of the four genera—Gazella, Nanger, Eudorcas and Antilope. Scientists are still debating the evolutionary relationships between these members. In a recent study, researchers at the Indian Institute of Science, Bengaluru, have traced the evolutionary relationships of the blackbuck (Antilope cervicapra) using phylogenetics. The study was published in the journal Molecular Phylogenetics and Evolution.
A team of researchers from the ATREE, Bengaluru, Concordia University, Canada, Quebec Centre for Biodiversity Science, Canada, and Jawaharlal Nehru Tropical Botanical Garden and Research Institute, Kerala, have traced the biogeographical origins of Piper genus in India.
Researchers from the Natural History Museum, London, have uncovered the evolutionary links between the different species of centipedes dating back to Gondwana.
Researchers at the NCBS, Bengaluru, studied how Swallowtails evolves and changes its appearance and colour at various stages of its elaborate life cycle to develop their colour defence strategies.
Researchers from IISER Pune, have reported that environment and evolution can influence the ‘dispersal syndrome’ in fruit flies. This study was supported by the DST, Government of India.
