Parallel evolution is a system whereby different populations can, even though they are in widely different areas, follow the same course of evolution to produce the same organisms at the end of the process. As evolution is based on random changes of...

Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition due to similar environments or other evolutionary pressures[1]. Frequently this is the situation in more closely related lineages, where...

Key words. Dung beetles, Hydrophilidae, Geotrupidae, Scarabaeidae, feeding habits, particle feeding, mouthparts, evolution Abstract. The maximum size of ingested ball-shaped particles was determined in three species of adult dung feeding beetle: Anoplotrupes (Geotrupes) stercorosus and Geotrupes spiniger (Geotrupidae, Geotrupinae) and Sphaeridium lunatum (Hydrophilidae,...

ABSTRACT Twelve populations of Escherichia coli evolved in and adapted to a glucose-limited environment from a common ancestor. We used two-dimensional protein electrophoresis to compare two evolved clones, isolated from independently derived populations after 20,000 generations. Exceptional parallelism was detected. We compared the...
