我们仍然需要解释的是更特化的真核生物的磷酸化途径是怎么进化而来并取代了细菌的系统。

What still needs to be explained is how the more typical eukaryotic phosphorylation cascades evolved and came to replace the bacterial systems.

争论的结果不仅仅影响我们对早期真核生物进化的理解，还影响我们对贾第虫属生物学的观点。

The outcome of this debate affects not only our understanding of early eukaryotic evolution, but also our view of Giardia biology.
