Essay: On the close relationship between speciation, inbreeding and recessive mutations. [PDF]
, 2010 Whilst the principle of adaptive evolution is unanimously recognised as being caused by the process of natural selection favouring the survival and/or reproduction of individuals having acquired new advantageous traits, a consensus has proven much harder

Cold Spring Harbor Perspectives in Biology, 2015 What are species? How do they arise? These questions are not easy to answer and have been particularly controversial in microbiology. Yet, for those microbiologists studying environmental questions or dealing with clinical issues, the ability to name and recognize species, widely considered the fundamental units of ecology, can be practically useful ...

Speciation patterns in predominately self-pollinated Mediterranean annuals [PDF]
, 1997 Many groups of annual plants in the Mediterranean basin are characterized by self-pollination. It is suggested that the breeding system operating in these plants affected considerably their mode of speciation. It is argued that the reproductive isolation

Resolution among major placental mammal interordinal relationships with genome data imply that speciation influenced their earliest radiations [PDF]
, 2010 Background: A number of the deeper divergences in the placental mammal tree are still inconclusively resolved despite extensive phylogenomic analyses.

Evolution of Divergent Female Mating Preference in Response to Experimental Sexual Selection [PDF]
, 2014 Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence between populations. However, few

Lanthanide Speciation in Potential SANEX and GANEX Actinide/ Lanthanide Separations Using Tetra-N-Donor Extractants [PDF]
, 2013 Lanthanide(III) complexes with N-donor extractants, which exhibit the potential for the separation of minor actinides from lanthanides in the management of spent nuclear fuel, have been directly synthesized and characterized in both solution and solid ...

No evidence for sympatric speciation [PDF]
, 2006 Sympatric speciation is difficult to demonstrate in nature and remains a hotly debated issue. Barluenga et al.1 present a case of putative sympatric speciation for two cichlid species in the Nicaraguan crater lake Apoyo, but they overlook or reinterpret ...

Current Opinion in Genetics & Development, 2004 Until recently, the genes that cause reproductive isolation remained black boxes. Consequently, evolutionary biologists were unable to answer several questions about the identities and characteristics of "speciation genes". Over the past few years, however, evolutionary geneticists have finally succeeded in isolating several such genes, providing our ...
