Critics have also complained that the living fossil concept is vague and/or ambiguous, and that it is responsible for misconceptions about evolution. First, recent research has challenged the status of paradigmatic living fossil taxa, such as coelacanths, cycads, and tuataras. Lately there has been a wave of criticism of the concept of living fossils.
