The shared ancestor — the Ancient North Eurasian population — is real and significant.

But the cousins got to where they are today by completely separate routes.

The correct framing is: some Native American populations carry genetic ancestry derived from an ancient Siberian population whose genetic heritage was also ancestral, through a different pathway, to some components of modern western Eurasian populations.

The connection is real but ancient, and it says nothing about modern European identity or modern Native American identity.
