1 Introduction Historical climate change is one of the major drivers in speciation (Hua and Wiens 2013; Carstens and Knowles 2007). Climate change has a drastic effect on adaptation of a population, and in the long term, also affects the process of speciation (Hoffmann and Sgró 2011; Hua and Wiens 2013; Parmesan 2006). Recent exacerbation of climate change have also documented this effect as many species have shifted their range to a more favorable habitat (Evans et al. 2020; Neumann et al.

New Results doi: https://doi.org/10.1101/2023.02.25.530015 Abstract Objectives: To ascertain the effect of historical demography and past climate change as the drivers of diversity in northeast India. Materials and methods: We took the variant called whole genome files of nine species present in the northeast India from Primate genome sequencing consortium work and assessed each species historic effective population size by using Multiple Sequentially Markovian Coalescent (MSMC) tool.
