Was there ever a land bridge between Europe and America?

Answer 1

"No. The distance is far to great to drive even if their was a bridge. With the modern world's easy access to the plane their is no need to build one today."- Godot-59

The question doesn't ask about a physical man-made bridge, but a land bridge. An example of a "land bridge" might be the area currently beneath the North Sea that cuts the United Kingdom off from mainland Europe. This has been named "DoggerLand", as the area is known as Dogger Bank, and in shipping terms as Dogger. It's known to have been in use for animal and human passage due to the bones dredged up by Dutch trawlers. Remember though that this area is all part of the European continental shelf, and not as deeply submerged as the ocean bed beneath the Atlantic.

So to answer the question - No, there probably has never been a land bridge between Europe and America. They sit on two separate continental shelves, and the oceanic depths are too great in vast areas to have ever been exposed by falling sea levels during ice ages. It is theoretically possible that a crossing over the polar caps could have been made during ice ages, though the complete lack of vegetation and the distances involved, not to mention the sheer hostility of the environment make the actuality all but impossible. It would be an epic task for humankind with modern knowledge, let alone in prehistory.

However with all this said, it is projected that there may have been a time when earth was young that the continents were very close, and perhaps conjoined in places. At this time, if indeed it existed as reflected in contemporary projections, it would have been possible to pass from one point to another that later became separate continents, however this time would pre-date most known forms of life on this planet, let alone mankind.
