In this view, the cilium is regarded as originated from the slender cell of a spirochete that established an external symbiosis with an eukaryotic ancestor; the symbiosis was followed by the fus

Nitrogen fixation has been incorporated into eukaryotes via symbiotic, endosymbiotic, and endophytic bacteria but not as true organelles like mitochondria and chloroplasts. We have considered possible explanations for the absence of nitrogen-fixing organell

The complexity increases by an order of magnitude when two parents share in the care of the offspring. Here, the mates must be coordinated with each other as well as with the needs of the developing young

However, genetic studies have been unable to identify the genomic signatures responsible for such heritability, as identifying the genetic variants that make a population prone to a given disease is not enough to explain its high occurrence within the population. This gap is kn
