96% of marine animal species became extinct in the permian mass extinction at the end of the paleozoic, 252 million years ago. why does the blue curve show only a 50% drop at that time?

Families typically contain may species, so the percentages of families that became extinct is lower than the percentage of species that became extinct.




Hope that helps!!!!!
