Re-description of the early Triassic diapsid Palacrodon from the lower Fremouw formation of Antarctica.

Publication Type: Academic Journal

Source(s): Journal of anatomy [J Anat] 2022 Dec; Vol. 241 (6), pp. 1441-1458. Date of Electronic Publication: 2022 Sep 27.

Abstract: The rapid radiation and dispersal of crown reptiles following the end-Permian mass extinction characterizes the earliest phase of the Mesozoic. Phylogenetically, this early radiation is difficult to interpret, with polytomies near the crown node, long ...

Environmental drivers of the first major animal extinction across the Ediacaran White Sea-Nama transition.

Publication Type: Academic Journal

Source(s): Proceedings of the National Academy of Sciences of the United States of America [Proc Natl Acad Sci U S A] 2022 Nov 16; Vol. 119 (46), pp. e2207475119. Date of Electronic Publication: 2022 Nov 07.

Authors:

Abstract: The Ediacara Biota-the oldest communities of complex, macroscopic fossils-consists of three temporally distinct assemblages: the Avalon (ca. 575-560 Ma), White Sea (ca. 560-550 Ma), and Nama (ca. 550-539 Ma). Generic diversity varies among assemblages,...

AvP: A software package for automatic phylogenetic detection of candidate horizontal gene transfers.

Publication Type: Academic Journal

Source(s): PLoS computational biology [PLoS Comput Biol] 2022 Nov 09; Vol. 18 (11), pp. e1010686. Date of Electronic Publication: 2022 Nov 09 (Print Publication: 2022).

Abstract: Horizontal gene transfer (HGT) is the transfer of genes between species outside the transmission from parent to offspring. Due to their impact on the genome and biology of various species, HGTs have gained broader attention, but high-throughput methods...

Male survivorship and the evolution of eusociality in partially bivoltine sweat bees.

Publication Type: Academic Journal

Source(s): PloS one [PLoS One] 2022 Oct 20; Vol. 17 (10), pp. e0276428. Date of Electronic Publication: 2022 Oct 20 (Print Publication: 2022).

Authors:

Abstract: Eusociality, where workers typically forfeit their own reproduction to assist their mothers in raising siblings, is a fundamental paradox in evolutionary biology. By sacrificing personal reproduction, helpers pay a significant cost, which must be outwe...

Evolution: The evolutionary rat race in New Guinea and Australia.

Publication Type: Academic Journal

Source(s): Current biology : CB [Curr Biol] 2022 Oct 10; Vol. 32 (19), pp. R1010-R1012.

Abstract: A new molecular phylogeny of a remarkable radiation of New Guinean and Australian rodents indicates multiple transitions between biomes and biogeographical regions within the group, and suggests that a key role was played by the geological history of N...

How gene duplication diversifies the landscape of protein oligomeric state and function.

Publication Type: Academic Journal

Source(s): Current opinion in genetics & development [Curr Opin Genet Dev] 2022 Oct; Vol. 76, pp. 101966. Date of Electronic Publication: 2022 Aug 22.

Abstract: Oligomeric proteins are central to cellular life and the duplication and divergence of their genes is a key driver of evolutionary innovations. The duplication of a gene coding for an oligomeric protein has numerous possible outcomes, which motivates q...

Massive Loss of Transcription Factors Promotes the Initial Diversification of Placental Mammals.

Publication Type: Academic Journal

Source(s): International journal of molecular sciences [Int J Mol Sci] 2022 Aug 26; Vol. 23 (17). Date of Electronic Publication: 2022 Aug 26.

Abstract: As one of the most successful group of organisms, mammals occupy a variety of niches on Earth as a result of macroevolution. Transcription factors (TFs), the fundamental regulators of gene expression, may also have evolved. To examine the relationship ...

The simple emergence of complex molecular function.

Publication Type: Academic Journal

Source(s): Philosophical transactions. Series A, Mathematical, physical, and engineering sciences [Philos Trans A Math Phys Eng Sci] 2022 Jul 11; Vol. 380 (2227), pp. 20200422. Date of Electronic Publication: 2022 May 23.

Authors:

Abstract: At odds with a traditional view of molecular evolution that seeks a descent-with-modification relationship between functional sequences, new functions can emerge de novo with relative ease. At early times of molecular evolution, random polymers could h...

impMKT: the imputed McDonald and Kreitman test, a straightforward correction that significantly increases the evidence of positive selection of the McDonald and Kreitman test at the gene level.

Publication Type: Academic Journal

Source(s): G3 (Bethesda, Md.) [G3 (Bethesda)] 2022 Sep 30; Vol. 12 (10).

Abstract: The McDonald and Kreitman test is one of the most powerful and widely used methods to detect and quantify recurrent natural selection in DNA sequence data. One of its main limitations is the underestimation of positive selection due to the presence of ...

Assortment and Reciprocity Mechanisms for Promotion of Cooperation in a Model of Multilevel Selection.

Publication Type: Academic Journal

Source(s): Bulletin of mathematical biology [Bull Math Biol] 2022 Sep 22; Vol. 84 (11), pp. 126. Date of Electronic Publication: 2022 Sep 22.

Authors:

Abstract: In the study of the evolution of cooperation, many mechanisms have been proposed to help overcome the self-interested cheating that is individually optimal in the Prisoners' Dilemma game. These mechanisms include assortative or networked social interac...
