Human metabolic adaptations and prolonged expensive neurodevelopment: A review
1. After weaning, human hunter-gatherer juveniles receive substantial (≈3.5-7 MJ day-1), extended (≈15 years) and reliable (kin and nonkin food pooling) energy provision.2. The childhood (pedia…

Early Life Relict Feature in Peptide Mass Distribution
Molecular mass of a biomolecule is characterized in mass spectroscopy by the monoisitopic mass Mmono and the average isotopic mass Mav. We found that peptide masses mapped on a plane made by tw…

Nucleotide repeats in mitochondrial genome determine human lifespan
Direct nucleotide repeats can facilitate deletions of segments of mitochondrial genome1, leading to a wide range of neuromuscular disorders1,2 as well as aging2,3 in humans. We hypothesized that th…

New species from the deep Pacific suggest that carnivorous sponges date back to the Early Jurassic
Some deep-sea poecilosclerid sponges (Porifera) have developed a carnivorous feeding habit that is very surprising in sponges1. As shown by the typical morphology of their spicules, they most pro…

Using Trees: Myrmecocystus Phylogeny and Character Evolution and New Methods for Investigating Trait Evolution and Species Delimitation (PhD Dissertation)
1) Rates of phenotypic evolution have changed throughout the history of life, producing variation in levels of morphological, functional, and ecological diversity among groups. Testing for the pres…

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…

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…

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…
