“…Hybridization between Hanuman langurs ( Semnopithecus spp.) and T. pileatus has also been proposed as a reason for the speciation of T. geei as the present distribution of the species falls into hybridization zone of both Hanuman langurs and capped langur (Arekar et al, 2021).…”

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. We also constructed species distribution models on past (Pliocene and Pleistocene) and present climate with Maxent, by utilizing publicly available distribution data for each species. Results: We got the effective population sizes for 10 million years ago at most, though we considered the data only till 3.3 million years. All species showed rise and decline at various time periods. The species distribution models showed disparate distribution at all three time points with a genera-wise pattern emerging. Discussion: We found that the evolutionary trajectories of all the four genera into consideration, Macaca, Trachypithecus, Hoolock and Nycticebus are different from each other. Species in Macaca looks to be evolved in northeast as well as come from southeast Asia. Some species of Trachypithecus seems to radiated in the northeast India. Similarly, Hoolock has evolved in the region and Nycticebus is predicted have arrived from Indochina in the region. Hence, this study provides unique insights to the evolutionary dynamics for primate species in the northeast India.

“…Furthermore, to test for putative hybrid speciation coalescent simulations could have been used to test for a best‐fit demographic scenario (Arekar et al 2021) like in ABC analysis (Shaner et al 2015) or DIYABC analysis (Pöschel et al 2018, Lin et al 2023) or to quantify introgression using ABBA‐BABA tests (Zarza et al 2016).…”

“…in southern Sichuan, Fig. 2A), which remains to be tested using appropriate methods (Joly et al 2009, Arekar et al 2021). Accordingly, in a critical reappraisal, two independent teams of authors came to the same conclusion that only four out of seven hybrid bird species postulated at that time met proper criteria for species status under a given species concept (Hill and Zink 2018; Ottenburghs 2018).…”

No evidence of a hybrid origin of the ashy‐throated parrotbill Sinosuthora alphonsiana

This mini‐review is dedicated to a critical re‐appraisal of the putative hybrid origin of the grey‐cheeked populations of the ashy‐throated parrotbill Sinosuthora alphonsiana that was postulated based on the results of a clustering analysis using a set of five nuclear loci. However, the number of genetically admixed individuals is lower than 10% in the proposed hybrid form and largely restricted to a single population in closest vicinity of one proposed parental taxon. Based on total evidence from mitochondrial and nuclear markers the proposed hybrid taxon is indistinguishable from the second postulated parental taxon. Wide‐range allelic introgression in a broad zone of range overlap along with incomplete lineage sorting of nuclear markers is a more plausible alternative explanation for the patterns observed. So far, there is no convincing evidence of a hybrid origin of the grey‐cheeked ashy‐throated parrotbill populations.
