Gene drive is a naturally occurring phenomenon in which selfish genetic elements
manipulate gametogenesis and reproduction to increase their own transmission to the next …

Collective personalities refer to temporally consistent behavioral differences between
distinct social groups. This phenomenon is a ubiquitous and key feature of social groups in …

Long-term suppression of recombination ultimately leads to gene loss, as demonstrated by
the depauperate Y and W chromosomes of long-established pairs of XY and ZW …

Nonrecombining genomic variants underlie spectacular social polymorphisms, from bird
mating systems to ant social organization. Because these “social supergenes” affect multiple …

Greenbeard genes were proposed as a cartoonish thought experiment to explain why
altruism can be a selfish strategy from the perspective of genes. The likelihood of finding a …

Chromosome inversions have clear effects on genome evolution and have been associated
with speciation, adaptation, and the evolution of the sex chromosomes. In birds, these …

Background A major focus of evolutionary biology is the formation of reproductive barriers
leading to divergence and ultimately, speciation. Often, it is not clear whether the separation …

Ants exhibit a striking diversity of reproductive systems, varying in traits such as the number
of reproductives per colony [1], the mode of daughter production (sexual or asexual)[2], and …

Queen discrimination behavior in the fire ant Solenopsis invicta maintains its two types of
societies: colonies with one (monogyne) or many (polygyne) queens, yet the underlying …

Olfaction is one of the most commonly used senses for communication among animals and
is of particular importance to mother-offspring recognition in mammals. The use of smell in …
