A map showing Eastern US sea levels today and during the last ice age, when the sea was up to 120 m lower:<p><a href="http:&#x2F;&#x2F;pubs.usgs.gov&#x2F;circ&#x2F;c1075&#x2F;images&#x2F;sea.gif" rel="nofollow">http:&#x2F;&#x2F;pubs.usgs.gov&#x2F;circ&#x2F;c1075&#x2F;images&#x2F;sea.gif</a><p>Interestingly, there is little change near the southern tip of Florida, which might explain the locations of the findings in TFA.<p>As you can seeon the map, huge areas were dry land then but are ocean today. On a global scale, these include the entire Hudson Bay, and all the sea between the UK and Western&#x2F;Northern Europe.<p>So I guess your theory isn&#x27;t controversial at all.
