About 11, 000 years ago, the ice age locked up most of the water the polar circles hence the ocean levels were lo exposing the Bering Strait crossing. This allowed organisms to cross between the two continents.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
