Ashikenazi Jews are a unique group which generally presents it's own peculiar "look," not quite native European nor quite Middle-Eastern.
Their situation is reminiscent of the Gypsy . The Gypsies were originally from India, but over the course of centuries they have inter-bred with Europeans and others to produce a peculiar phenotype not quite European nor quite Indian.
In the case of the primordial Jewish population which entered Europe, the inter-breeding with the host population was a little bit more intense and systematic (due to regular Gentile conversions into their ranks), so they often present the more European look than the gypsy. But their "unique" look remains, because they're not totally indigenous to Europe. Here's a picture of Bob Dylan and Adam Sandler, two Jews from two completely different Jewish families. But they could pass off as twins.
