Evolutionary Biology

Evolutionary Biology is a subfield in biology that is concerned with the gradual change in the traits of living organisms over generations, especially the emergence of new species. It studies the sequence of events involved in the evolutionary development of a species or of a taxonomic group of organisms.

Roots: evolutionary origins and biogeochemical significance
This review considers root evolution by attempting to define the root and, in so doing, delimiting its difference from the shoot, and by considering the functions of the roots of extant plants and cases in which ‘root’ functions are performed by non-r
