Paleolithic and neolithic lineages in the European mitochondrial gene pool.
It follows that the major extant lineages throughout Europe predate the Neolithic expansion and that the spread of agriculture was a substantially indigenous development accompanied by only a relatively minor component of contemporary Middle Eastern agriculturalists.
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.
Genetic diversity in the Iberian Peninsula determined from mitochondrial sequence analysis
The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic, and lineage diversity comparisons with European and North African populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberians lineages can be traced to North Africa.

The role of isolated islands in allopatric speciation of these organisms is discussed in relation to dispersal and the usefulness of Macaronesia as a model system to explore speciation in intertidal organisms is emphasized.
Intron-targeted PCR: a new approach to survey neutral DNA polymorphism in bivalve populations
It is shown that there are at least two calmodulin genes in mussels of the Mytilus edulis species complex, and using gene- and species-specific primers the authors resolve two alleles at a cal modulin intron locus.

Morphological analyses of shell shape and radular morphology and electrophoretic results did not distinguish the two species clearly, but it is proposed that P. piperata, on the basis of the genetic data obtained, may represent a subspecies of P. rustica that is in the process of diverging due to its geographic isolation.
Inheritance of a nuclear DNA polymorphism assayed in single bivalve larvae
Evidence is found that each allele can be inherited from either sex, that there are no barriers to fertilization between gametes of different genotypes, and that most larvae have genotypes compatible with Mendelian inheritance of the locus.
Population differentiation and taxonomic status of the exploited limpet Patella candei in the Macaronesian islands (Azores, Madeira, Canaries)
There has been considerable confusion in the taxonomy of limpets of the North East Atlantic Ocean and Mediterranean Sea, particularly those from the Macaronesian islands. The present study compared…
