The intricate adjustment of organisms to their environment demonstrates the effectiveness of
natural selection. But Darwin himself recognized that certain biological features could limit …

When mutation rates are low, natural selection remains effective, and increasing the mutation
rate can give rise to an increase in adaptation rate. When mutation rates are high to begin …

In the context of the ongoing SARS-CoV-2 pandemic, health officials warn that vaccines must
be uniformly distributed within and among countries if we are to quell the pandemic. Yet …

Selection is one of the factors that most influence the shape of genealogical trees. Here we
report results of simulations of the infinite-sites version of Moran's model of population …

We study the influence of random migration of a species (may be insects) in the population
dynamics when initially all the individuals live in a primordial site (their habitats may be trees)…

The ubiquity of genetic mixing in nature has eluded unified explanation since the time of
Darwin. Conditions that promote the evolution of genetic mixing (recombination) are fairly well …

Exchanging genetic material with another individual seems risky from an evolutionary stand-point,
and yet living things across all scales and phyla do so quite regularly. The …

In classical population genetics, mutation–selection balance refers to the equilibrium frequency
of a deleterious allele established and maintained under two opposing forces: recurrent …

The Magicicada spp. life cycles with its prime periods and highly synchronized emergence
have defied reasonable scientific explanation since its discovery. During the last decade …

Health officials have stressed the importance of a more uniform distribution of SARS-CoV-2
vaccines within and among countries, yet there has been little critical assessment of the …
