In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.
The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.
Prokaryotic and eukaryotic flagella follow a common trend in swimming cost-effectiveness, but eukaryotic flagella are too large for cells with prokaryote volumes, yielding insight into flagellar dissimilarity between taxa.

Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.
The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.
The ability of corals to adapt to global warming may involve trade-offs among the traits that influence their success as the foundational species of coral reefs.
