Isn't it acceptable that prior to the age of fossil records, life was going through unrecorded stages such as the plant, and prior to that the fungal, and prior to that the purely microbial, still only in the seas? Why does everyone assume that life can only mean 'life as we know it' ? Also, the Cambrian explosion is only an explosion in limited, modern terms. It would still have taken an amazing amount of time to unfold- 'all at once' in the context of the earth's history can still mean 'across millions of years' !
Fascinating. I never knew about the Cambrian Explosion. This makes me wonder about another suggestion regarding why complex life-forms appeared so abruptly in the geologic record:
Panspermia.
Many reports of "alien abductions" seem to have beings with arms, legs, heads, eyes, nose, and mouth. This makes me wonder if those "aliens" may be our cousins out in space.
