他们认为,在几十亿年前,包括RNA在内的单链核糖是生命的第一形态,完成一些现在由蛋白质来完成的复杂细胞功能。
They believe that billions of years ago, single strands of nucleotides that comprise RNA were the first forms of life and carried out some of the complicated cellular functions now done by proteins.
这或许就很好地解释了为什么两次那样的转变都与后来的进化飞跃有关——复杂细胞的首先诞生,接着就是大型动物的出现。
That may well be why both of those jumps seem to be associated with subsequent evolutionary leaps-the advent of complex cells, in the first place, and of large animals, in the second.

The simulated results for three special input functions show the finer structure of spatiotemporal integration coding series of complex cells in visual cortex could represent visual inputs.
It turns out that the kinds of post-translational modifications human cells are able to do are very complicated.
