The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.
Thymus ageing is characterised by both compositional and transcriptional shifts amongst epithelial cells that perturb their differentiation, contribute to organ atrophy and ultimately impair immune function.
Tool behaviour of long-tailed macaques leaves archaeological signatures that differ between populations despite similar ecological conditions, highlighting the potential for diversity in material culture.
In mountain gorillas, as in certain human populations, relationships between group members can act as a social buffer, breaking the link between maternal loss, increased social adversity, and decreased fitness.
A mathematical model for a popular biological diversity mechanism, cyclic dominance, is more likely to emerge by assembly than by evolutionary diversification, which rationalizes why few empirically studies find it.
A field study coupled with a molecular analysis demonstrates that using hematophagous flies as 'flying syringes' could be used to investigate blood-borne pathogen diversity in wild vertebrates and act as an early detection tool of zoonotic pathogens.
