@Leadfoot,
Quote: But ya get my point, your clock face spot for the Cambrian would hardly show up.
Just seems odd that the time when 99+ % of evolution happened is less than 2% of the time. But I'm sure you got a logical reason for that. Weather/conditions changed, oxygen atmosphere, etc. Yeah.
Youre dead wrong again . The majority of Paleozoic life appeared at about a rate 0f 98% of the species occuring AFTER the early Cambrian(and he bulk of the phyla already existing BEFORE the basal Cambrian
The proterozoic includes the Ediacaran segments that the real " medium Hard shell" fossils first appeared.(Dickinsonia etc)
Wjhen your creationist friends try to bamboozle the time sequence of life, the only thing that the 40 to 60 my segment of the"Cambrian Explosion" produced was hard parts of several species like gastropods and early trilobites.
Nice try but , you really have no point "to get"
From Archeozoa through Proterozoa look at the time spent to get life to a point where internal organs and eyes and eggs first appeared. Adding hard parts is hardly a point in time (At least 60 million years isnt. Look how quickly birds first occured, or amphibians through reptiles. How bout gymnosperms and first appearances of Angiosperms.
You are easily impressed, others are not.
I consider a million years a lot of time for animals to adapt and evolve, imagine several TENS OF MILLIONS.
