Evolving E. coli NfsA for enhanced chloramphenicol detoxification in the native host environment shows that eliminating substrate competition can occur rapidly, and be key to evolving a new enzymatic function.
Teeth and dermal odontodes diverge from the same set of founder odontodes, demonstrating they are modified subsets of the same system, and both oral and dermal epithelial have patterning capacity.

Subterranean isopods endemic to regions with large igneous rock formations have a higher mutation rate and display an excess of mutations that are typical of an oxidative stress.
Analysis of the smallest known arthropod genome reveals a mechanism for genome reduction that appears to be driven by a specialized ecological interaction with plants.

A larger non-recombining region in sexually dimorphic primates compared to sexually monomorphic ones supports the view that sexually antagonistic mutations have influenced the evolution of sex chromosomes in primates.

In-silico modeling of gene and protein emergence reveals how colony-stimulating factors contributed to the evolution and functional adaptions observed in mammalian neutrophils.
