Apparently , a mutation in this gene-or , more probably , in the control system that activates it-gave rise to volvox .
显然这个基因的突变,或更可能是激活这个基因的控制机制的突变产生了团藻。
What genetic change allowed multicellular animals to come into existence remains obscure . But volvox shows the sort of thing to look for : a gene that stops reproduction in single-celled creatures and has been co-opted to do a new job .
The gene that stops the body cells of volvox reproducing is called rega .
阻止团藻体细胞分化的基因叫做rega。
One creature that has managed the trick-separately from plants , animals and fungi , who are the real experts in the field-is an alga called volvox carteri .
