Evolutionary Biology: Volume 16

Max Hecht

en Limba Engleză Paperback – 12 oct 2012

Sixteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical re views, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that every facet of evolutionary biology-classical or modern-is cov ered. Manuscripts should be sent to anyone of the following: Max K.
