Yuan H, Dickson 3rd E, Martinez Q, Arnold P, Asher R
Proc Biol Sci . 2024 Dec; 291(2037):20241856. PMID: 39689883
Shrews are among the most speciose of mammalian clades, but their evolutionary history is poorly understood. Their fossil record is fragmentary and even the anatomy of living groups is not...

Hautier L, Gomes Rodrigues H, Ferreira-Cardoso S, Emerling C, Porcher M, Asher R, et al.
Proc Biol Sci . 2023 Nov; 290(2011):20231932. PMID: 38018114
Sirenians are a well-known example of morphological adaptation to a shallow-water grazing diet characterized by a modified feeding apparatus and orofacial morphology. Such adaptations were accompanied by an anterior tooth...

Christensen M, Hallikas O, Das Roy R, Vaananen V, Stenberg O, Hakkinen T, et al.
Proc Natl Acad Sci U S A . 2023 Jun; 120(25):e2300374120. PMID: 37307487
When evolution leads to differences in body size, organs generally scale along. A well-known example of the tight relationship between organ and body size is the scaling of mammalian molar...

Alvarez-Carretero S, Tamuri A, Battini M, Nascimento F, Carlisle E, Asher R, et al.
Nature . 2021 Dec; 602(7896):263-267. PMID: 34937052
High-throughput sequencing projects generate genome-scale sequence data for species-level phylogenies. However, state-of-the-art Bayesian methods for inferring timetrees are computationally limited to small datasets and cannot exploit the growing number of...

Asher R
Cladistics . 2021 Dec; 15(3):231-252. PMID: 34902947
A phylogenetic analysis of 35 mammalian taxa focusing on the lipotyphlan family Tenrecidae, based on 193 morphological character states across 71 characters, is undertaken to test several hypotheses of lipotyphlan...

Asher R, Smith M
Syst Biol . 2021 Sep; 71(4):986-1008. PMID: 34469583
An unprecedented amount of evidence now illuminates the phylogeny of living mammals and birds on the Tree of Life. We use this tree to measure the phylogenetic value of data...

Gomes Rodrigues H, Tabuce R, Asher R, Hautier L
Evol Dev . 2020 May; 22(4):323-335. PMID: 32353920
Understanding the origins of morphological specializations in mammals is a key goal in evolutionary biology. It can be accomplished by studying dental homology, which is at the core of most...

Asher R, Smith M, Rankin A, Emry R
R Soc Open Sci . 2019 Aug; 6(7):190387. PMID: 31417738
Given an evolutionary process, we expect distinct categories of heritable data, sampled in ever larger amounts, to converge on a single tree of historical relationships. We tested this assertion by...

Davies T, Rahman I, Lautenschlager S, Cunningham J, Asher R, Barrett P, et al.
Proc Biol Sci . 2017 Apr; 284(1852). PMID: 28404779
Over the past two decades, the development of methods for visualizing and analysing specimens digitally, in three and even four dimensions, has transformed the study of living and fossil organisms....

Thean T, Kardjilov N, Asher R
J Anat . 2016 Dec; 230(2):249-261. PMID: 27995620
Cetaceans face the challenge of maintaining equilibrium underwater and obtaining sensory input within a dense, low-visibility medium. The cetacean ear represents a key innovation that marked their evolution from terrestrial...
