Increasing awareness that many causal links in biology might be bi-directional could overcome biases and improve scientific reasoning.

The discovery of a fossil heart in Rhacolepis buccalis demonstrates that it is possible to scrutinize the fossil record for important clues on cardiac structure and evolution.

Both gill musculature and the evolutionarily conserved cucullaris muscle are derived from unsegmented mesoderm adjacent to the first 3 somites, extending the posterior limit of cranial mesoderm.

Many natural isolates of budding yeast carry extra chromosome copies and show lower-than-expected expression at a subset of amplified genes, which show unique evolutionary signatures.

Endogenous virus sequences in the genomes of modern mammals reveal the global spread of an ancient virus lineage, including frequent interspecies transmission, adaptation, and emergence spanning several million years of mammalian evolution

eLife has published papers on topics as diverse as paleoproteomics, ancient insects and the discovery of a new hominin species.

Mathematical modeling supports a scenario where cell-cell adhesion gradually evolves through natural selection, leading to the emergence of cohesive aggregates in microbial populations.

Cells of the xanthophore lineage form projections that allow them to communicate with other pigment cells during adult pigment pattern formation in zebrafish, but not in the closely-related pearl danio.
