Prehistoric rock art in Africa and cave paintings in Europe are thought to represent ancient ritual practices, including the healer's transformation into a creature form.

These were like worlds within worlds of microbiological gestalts which I found could then be further transcribed using my grid system to render more musical punch cards.

这些宛如微生物形态内在世界，我发现可以通过我网格系统进一步转录，转化为更具音乐性穿孔卡片。仿佛在一首歌中发现了隐藏旋律。

如果你能以查尔斯·达尔文追溯生物形态进化方式，追踪这些故事中某种演变脉络，会怎样呢？

As we were saying before, I think the move from life to consciousness, the kinds of beings that would build what we would recognize as a civilization, that may be extraordinarily rare.

如我们之所讨论， 我认为从生命到意识跃迁，以及那些能够构建出我们认知中文明形态生物种类，可能是极其罕见。
