阻止团藻的体细胞生殖的基因叫regA。
The gene that stops the body cells of Volvox reproducing is called regA.
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。
Apparently, a mutation in this gene-or, more probably, in the control system that activates it-gave rise to Volvox.
因此个体细胞根据他们在团藻中所具有的功能打开或关闭控制繁殖能力的开关。
When that happened, individual cells could turn their reproductive capacity on or off according to the function they served in Volvox's body.
由相同类型和功能的细胞组成的生物体，在许多藻类中存在，例如团藻。
Colony a body form in which many cells with similar form and function are grouped together, as in many algae, e. g. Volvox.
还有像团藻属类样子的东西，它们是小小的挤作一团的球状生物，而不是像书上所称的微生物那样各自分开。
There were Volvox lookalikes, round balls of little creatures fused together to make a sphere of life rather than a separated quantity of what books like to call animalcules.
毫无疑问团藻是由类似的只以单细胞形式存在的藻类进化而来，但直到现在这一过程的遗传学原理依然模糊不清。
Clearly, Volvox evolved from similar algae that exist only as single cells, but until now the genetics of the process have been obscure.
有一种生物成功做到了这些，它们是从植物、动物和真菌中分离出来的这一领域的真正专家——一种叫团藻Volvox carteri的藻类。
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.
