"Latimeria was first labelled as a 'living fossil' because the fossil genera were known before the extant species was discovered, and erroneous biological interpretations have grown and reports still show little morphological and molecular evolution. A closer look at the available molecular and morphological data has allowed us to show that most of the available studies do not show low substitution rates in the Latimeria genome, and furthermore, as pointed out by Forey [3] long before us, the supposed morphological stability of coelacanths from the Devonian until the present is not based on real data. As a consequence, the idea that the coelacanth is a biological 'living fossil' is a long held but false belief which should not bias the interpretation of molecular data in extant Latimeria populations."
Se ei siis edusta mitään muinaista varsieväkalasukua, vaan on morfologialtaan aivan oma sukunsa, joka on muuttunut evoluution avulla aivan evoluution normaalivauhtia myös geneettisesti ja molekyylitasolla.
Kyseessä on siis vain väärä käsitys.
