Developmental plasticity and the origin of novel forms: unveiling cryptic genetic variation via "use and disuse"A Richard Palmer
Systematics and Evolution Group, Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada
J Exp Zool B Mol Dev Evol 318:466-79. 2012..Evidence from several sources suggests that handed behaviors played an important role both in the origin of novel forms (asymmetries) and in their subsequent evolution...
Scale-eating cichlids: from hand(ed) to mouthA Richard Palmer
Systematics and Evolution Group, Department of Biological Sciences, University of Alberta, Edmonton, AB T6G2E9, Canada
J Biol 9:11. 2010..They also suggest a fascinating new line of research testing the effects of handed behavior on morphological asymmetry...
From symmetry to asymmetry: phylogenetic patterns of asymmetry variation in animals and their evolutionary significanceA R Palmer
Department of Biological Sciences, University of Alberta, Edmonton, Canada
Proc Natl Acad Sci U S A 93:14279-86. 1996....
Symmetry breaking and the evolution of developmentA Richard Palmer
Systematics and Evolution Group, Department of Biological Sciences, University of Alberta, Edmonton, AB T6G 2E9, Canada
Science 306:828-33. 2004..Finally, declining frequencies of spontaneous asymmetry reversal throughout vertebrate evolution suggest that heart development has become more canalized...
Chimpanzee right-handedness reconsidered: Evaluating the evidence with funnel plotsA Richard Palmer
Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Am J Phys Anthropol 118:191-9. 2002..Funnel plots, and the more refined statistical tests they suggest, confirm that the current evidence for population-level right-handedness in chimpanzees remains equivocal...
Reproduction: widespread cloning in echinoderm larvaeAlexandra A Eaves
Physiology and Cell Biology Group, Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Nature 425:146. 2003..Larval cloning may therefore be an ancient ability of echinoderms and possibly of deutero-stomes - the group that includes echinoderms, acorn worms, sea squirts and vertebrates...
Precisely proportioned: intertidal barnacles alter penis form to suit coastal wave actionChristopher J Neufeld
Department of Biological Sciences, University of Alberta, Edmonton, AB, Canada T6G 2E9
Proc Biol Sci 275:1081-7. 2008..This dramatic plasticity in genital form is a valuable reminder that factors other than the usual drivers of genital diversification--female choice, sexual conflict and male-male competition--can influence genital form...
Morphological phylogeny of alpheid shrimps: parallel preadaptation and the origin of a key morphological innovation, the snapping clawArthur Anker
Systematics and Evolution Group, Department of Biological Sciences, University of Alberta, Edmonton, Alberta T6G 2E9, Canada
Evolution 60:2507-28. 2006..Thus one key innovation (orbital hoods) may have facilitated evolution of a second (snapping claws)...
Selection for asymmetryA Richard Palmer
Science 306:812-3; author reply 812-3. 2004

Left-right patterning from the inside out: widespread evidence for intracellular controlMichael Levin
Forsyth Center for Regenerative and Developmental Biology, The Forsyth Institute, Harvard School of Dental Medicine, Boston, MA 02115, USA
Bioessays 29:271-87. 2007..Late-developing asymmetries pose a challenge to the intracellular model, but early mid-plane determination in many groups increases its plausibility. Multiple experimental tests are possible...
Evolutionary biology: caught right-handedA Richard Palmer
Nature 444:689-92. 2006
