Ask the Swan Specialist
Date: 6 December 2016
Fossils found in North America were determined to be the ancestors of Mute, Black-Necked, Trumpeter and Tundra Swans. Some scientists believe that the Mute Swans originated in Europe, however, with the fossil records, one has to look at their origin being from North America.
There are many points to this issue including the fact that in pre-historic times, there were land bridges in which people, animals and birds could cross back and forth among the continents, so origin of any species is something that must be examined further. At this point in time, there is a debate on whether species originated at the point of their ancestors or whether they evolved at other points due to some climatic change or other environmental cause. This is known as adaptive radiation and there are scientists that are investigating this issue.
Hopefully, some day we will know more, but at this time there are very few bird fossils due to the possibility that the fossils are beneath land and even water. Until the fossils are discovered, the issue of whether a species evolved prior to leaving their ancestral land or after, remains a new frontier to discover and investigate. The Regal Swan
