Several things, however, suggest that the conventional view needs
revising. {{U}}For example,{{/U}} the genus Lingula has an unbroken fossil record
extending over more than half a billion years to the present. Thus, if longevity
is any measure, brachiopods are the most successful organisms extant. Further,
recent studies suggest that diversity among species is a less important measure
of evolutionary success than is the ability to withstand environmental change,
such as when a layer of clay replaces sand on the ocean bottom. The relatively
greater uniformity among the existing brachiopod species may offer greater
protection from environmental change and hence may reflect highly successful
adaptive behavior.
