Darwin and microbial evolutionced its organization indicating that the gene pool available in the microbial world is far larger than previously thought. As per established knowledge of microbial genetics, local DNA sequence changes, segment-wise rearrangement of genomic DNA sequences by recombinational reshuffling and horizontal

Evolutionary relationships among cyanobacteria, algae and plants: Revisited in the light of Darwinisn years ago. Among algae, blue green algae or cyanobacteria represent an ancient group of photosynthetic prokaryotes, whose ubiquity, metabolic flexibility and adaptive abilities have made them a subject of research worldwide. Their biological significance, especially as the prokaryotic interface be

Biodiversity, phylogeny and evolution of fungit, believed to be similar to modern day .. This Taphrina-like ancestor was believed to have given rise to the ancestral Basidiomycota..Monophyletic origin of fungi was followed by most of the mycologists till 1960s. But, some mycologists proposed polyphyletic origin, with red algae as origin of Asco

Adaptive radiation and insectsto establish that adaptive radiation has taken place and all these focus toward aspects of microevolution and macroevolution. Many times the ecological, reproductive, stratigraphic, barriers due to abiotic factors are the ones that are focused toward establishing the facts on adaptive radiation..The

The saga of pollination biologyomplished with utmost accuracy amidst various challenges such as immobility of plants and the vagaries of environment that carry the pollen. Flowering plants have accommodated both biotic and abiotic means of pollen transfer. A vast array of floral adaptations such as showiness, colouration, nectar

Pathogen pressure and molecular evolutionary genetics of innate immunity genes in humansolutionary ancient, the system may have been highly optimized by natural selection and therefore should be under purifying selection and (b) the system may be plastic and continuing to evolve under balancing selection. We have found that in these genes, there is (a) generally an excess of rare varia

Macroevolution in relation to the drift models of the Indian platee-Early Eocene; and mammalian diversification happened in the northern Indian landmass in response to progressive land emergence and Tethyan sea withdrawals. Strong trends in fluctuations in biodiversity of mammals in response to orbital forcing and climatic shifts are observed during periods of gla
