Complete mitochondrial genomes provide current refined phylogenomic hypotheses for relationships among ten Hirundo species

open access: yesMitochondrial DNA. Part B. Resources, 2020
Hirundo is the most species-rich genus of the passerine swallow family (Hirundinidae) and has a cosmopolitan distribution. Here we report the complete, annotated mitochondrial genomes for 25 individuals from 10 of the 14 extant Hirundo species; these ...

Evolution of Generalists by Phenotypic Plasticity

open access: yesiScience, 2020
Summary: Adapting organisms face a tension between specializing their phenotypes for certain ecological tasks and developing generalist strategies that permit persistence in multiple environmental conditions.

Opposing effects of plant traits on diversification

open access: yesiScience, 2023
Summary: Species diversity can vary dramatically across lineages due to differences in speciation and extinction rates. Here, we explore the effects of several plant traits on diversification, finding that most traits have opposing effects on ...

Consciousness and evolutionary biology

open access: yesAnimal Sentience, 2016
Reber’s axiom: “Any organism with flexible cell walls, a sensitivity to its surrounds and the capacity for locomotion will possess the biological foundations of mind and consciousness” does not seem to be supported by things we know and the logic of ...

A de novo evolved gene in the house mouse regulates female pregnancy cycles

open access: yeseLife, 2019
The de novo emergence of new genes has been well documented through genomic analyses. However, a functional analysis, especially of very young protein-coding genes, is still largely lacking.

Transcriptional effects of a positive feedback circuit in Drosophila melanogaster

open access: yesBMC Genomics, 2017
Background Synthetic systems that use positive feedback have been developed to control human disease vectors and crop pests. The tTAV system, which has been deployed in several insect species, relies on a positive feedback circuit that can be inhibited ...

The logic of transgenerational inheritance in a nematode worm

open access: yesiScience
Summary: Epigenetic inheritance of environmentally induced phenotypes across generations has been observed in multiple taxa. However, the dynamics of non-genetic inheritance as a consequence of environmental variability remains poorly understood.

More on how and why : a response to commentaries [PDF]

open access: yes, 2013
We are grateful to the commentators for taking the time to respond to our article. Too many interesting and important points have been raised for us to tackle them all in this response, and so in the below we have sought to draw out the major themes ...
