The human brain differs from that of other primates, but the genetic basis of these differences remains unclear.
Most evolutionary analyses are based on pre-estimated multiple seq
An evolutionary process is reflected in the sequence of changes of any trait (e.g., morphological or molecular) through time.
The fitness cost associated with the production of bacterial capsules is considered to be offset by the protection provided by these extracellular structures against biot
Prokaryotes use CRISPR–Cas systems for adaptive immunity, but the reasons for the frequent existence of multiple CRISPRs and cas clusters remain poorly understood.
We test the hypothesis that the frequency and cost of extracellular proteins produced by bacteria, which often depend on cooperative processes, vary with habitat structur
