Which of the following is the most likely organism to fossilize and be found in the fossil record?
The earliest forms of bacteria
A jellyfish with a soft body
An octopus with a soft body
A crustacean with a hard exoskeleton
All of the following have been suggested as triggers for the Cambrian
radiation of complex metazoans except:
perhaps the Cambrian metazoans outcompeted the Ediacaran metazoans,
opening up new ecological niches to fill
perhaps a series of fortuitsus genetic changes provided more raw material for
natural selection to act upon
perhaps increased oxygen in the world ocean promoted the evolution of
complex body forms
perhaps the rise in sea level that flooded the margins of the continents during
the earliest Paleozoic created abundant new ecological niches, promoting
biodiversity
O perhaps the "arms race" between predator and prey spurred evolutionary
innovation
To what subclass does this animal belong?
Theria
Metatheria
Protheria
Mammalia
Ornitheria
