    Recalibrated tree of leaf beetles (Chrysomelidae) indicates independent diversification of angiosperms and their insect herbivores. by Jesús Gómez-Zurita, Toby Hunt, Fatos Kopliku, Alfried P Vogler

    Published 2007-04-01
    “…Molecular clock calibrations and confidence intervals were based on paleontological data from the oldest (K-T boundary) leaf beetle fossil, ancient feeding traces ascribed to hispoid Cassidinae, and the vicariant split of Nearctic and Palearctic members of the Timarchini.The origin of the Chrysomelidae was dated to 73-79 Mya (confidence interval 63-86 Mya), and most subfamilies were post-Cretaceous, consistent with the ages of all confirmed body fossils. …”

    Published 2009-12-01
    “…The <it>Gypsy </it>retroelement of the <it>melanogaster </it>subgroup probably invaded the <it>Zaprionus </it>genomes about 11 MYA. In contrast, the <it>Micropia </it>retroelement may have been introduced into the <it>Zaprionus </it>subgenus and the <it>melanogaster </it>subgroup from an unknown donor more recently (~3 MYA).…”

    Published 2017-05-01
    “…Their divergence was postulated to be attributable to the vicariant event which resulted from the isolation of the Sea of Japan during the middle Pliocene (c. 3.85 Mya, 95% HPD 2.23–6.07 Mya). Allopatric speciation was maintained by limited genetic exchange due to their habitat preferences. …”

    Convergence and divergence in the evolution of the APOBEC3G-Vif interaction reveal ancient origins of simian immunodeficiency viruses. by Alex A Compton, Michael Emerman

    Published 2013-01-01
    “…Using a broad panel of SIV Vif isolates, we demonstrate that natural variation in OWM A3G confers resistance to Vif-mediated degradation, suggesting that adaptive variants of the host factor were selected upon exposure to pathogenic lentiviruses at least 5-6 million years ago (MYA). Furthermore, in members of the divergent Colobinae subfamily of OWM, a multi-residue insertion event in A3G that arose at least 12 MYA blocks the activity of Vif, suggesting an even more ancient origin of SIV. …”

    On the mysterious Seychellois endemic spider genus Cenemus (Araneae, Pholcidae) by Bernhard A. Huber, Guanliang Meng

    Published 2023-02-01
    “…This supports the idea that Cenemus is an ancient taxon, dating back to the breakup of Gondwana, between the separation of the Mascarene platform from Madagascar (~85 mya) and its separation from India (~60 mya). In addition, we present first molecular data for the recently established Smeringopinae genus Maghreba Huber, 2022, which is consistently resolved as sister to Crossopriza Simon, 1893; we present molecular evidence for the polyphyly of Holocnemus Simon, 1873, supporting previous morphological evidence; and we present an annotated list of the Pholcidae of the Seychelles, most of which are supposedly recent human introductions.…”

Eguiarte

    Published 2021-09-01
    “…Our results show that recent demographic changes were consistent with global climatic changes (∼130,000 kyr ago for Cyt-b and ∼160,000 kyr for D-loop) and divergence times dated from molecular genealogies exhibited older divergence times, Cyt-b (4.03 mya), D-loop (10.26 mya) and DBY (12.23 mya). Accordingly, the female lineage underwent demographic expansion associated to Pleistocene climate change, whereas the male lineage remained constant.…”
