America seems to be incubating a number of its own unique coronavirus variants, new research suggests. A study posted Sunday that hasn't yet been peer reviewed identified seven new "lineages" of the virus, The New York Times reports. While the lineages evolved independently of one another, they seem to display the same genetic mutation.

The change is seen in a gene that influences how the virus finds its way into a host's cell, suggesting it could make these variants more contagious — though this hasn't been confirmed. "I think there's a clear signature of an evolutionary benefit," said Jeremy Kamil, a virologist at Louisiana State University Health Sciences Center and a co-author of the new study.
