Potential pathways of indole acetic acid (IAA) biosynthesis in Euphorbia abyssinica
Desert candle (Euphorbia abyssinica J.F. Gmel.) (further referred to as EAG) is a succulent tree of dry deciduous and evergreen montane forest, woodland and shrub savanna. It occurs widely through...

Towards realising Darwin’s dream: setting the trees free
The fact that all living organisms are related by common descent is one of the central principles of modern biology. Since the early 1990’s the amount of data available to evolutionary biolo...

Exaptation and emergence as mechanisms to cross fitness valleys during evolution: an example using simulated homing behaviour
Evolution is often considered a gradual hill climbing process, slowly increasing the fitness of organisms. I investigate the evolution of homing behaviour in simulated intertidal limpets. In order ...

Trichoplax, the simplest known animal, contains an estrogen-related receptor but no estrogen receptor: Implications for estrogen receptor evolution
Although, as their names imply, estrogen receptors [ERs] and estrogen-related receptors [ERRs] are related transcription factors, their evolutionary relationships to each other are not fully unders...

Courtship plasticity reveals the evolution of dialects in allopatric fish populations
Traditionally, reproductive isolation between disjoint populations has been thought to emerge as a result of the accumulation of different mutations, genetic drift, or through the effects of natura...

Characteristics of oligonucleotide frequencies across genomes: Conservation versus variation, strand symmetry, and evolutionary implications
One of the objectives of evolutionary genomics is to reveal the genetic information contained in the primordial genome (called the primary genetic information in this paper, with the primordial gen...

THE BRAIN IN BUSINESS: THE CASE FOR ORGANISATIONAL COGNITIVE NEUROSCIENCE?
The application of cognitive neuroscientific techniques to understanding social behaviour has resulted in many discoveries. Yet advocates of the ‘social cognitive neuroscience’ approach maintain th...

Comparative methods in R hackathon
The R statistical analysis package has emerged as a popular platform for implementation of powerful comparative methods to understand the evolution of organismal traits and diversification. A hacka...

SNP analysis reveals an evolutionary acceleration of the human-specific microRNAs
MicroRNAs are one class of important gene regulators at the post-transcriptional level by binding to the 3’UTRs of target mRNAs. It has been reported that human microRNAs are evolutionary conserved...

An ancient adaptive episode of convergent molecular evolution confounds phylogenetic inference
Convergence can mislead phylogenetic inference by mimicking shared ancestry, but has been detected only rarely in molecular evolution. Here, we show that significant convergence occurred in snake a...
