Cloned zygotes are not reliable because while all other cells in the body do contain a full set of DNA, these other cells optimize their DNA to best serve their own particular functions.

Because this system is responsible for taking care of particular functions only when you have the time and energy to do it — like digesting food or excreting waste — it uses more specific, strategic signals.

因为只有当你有时间和精力去做的时候，这个系统才负责照顾特定的功能——比如消化食物或排泄废物，它使用更具体的、战略性的信号。

Multiple parts are variable in number and in structure, perhaps arising from such parts not having been closely specialised for any particular function, so that their modifications have not been closely checked by natural selection.

多个部分在数量和结构上是可变的，可能是由于这些部分没有专门针对任何特定功能而产生的，因此它们的修改没有受到自然选择的严格检查。
