Abstract Aim 

To examine the effect of a known geological barrier on genetic variation within a wall lizard species complex. Location 

The Iberian Peninsula and North Africa. Methods 

Sequencing of partial 12S rRNA and cytochrome b mtDNA. Results 

The current distribution of genetic variability is not related to the opening of the Strait of Gibraltar. Conclusions 

Podarcis hispanica in North Africa is probably a species complex. The Strait of Gibraltar should not be used as a known barrier to gene flow in other land based organisms without careful sampling to test for multiple crossings since its formation.
