Scientists have used the distribution of fossils and rocks, continental shapes, and seafloor structures as evidence of past plate motions. alfred wegener, a german geophysicist, proposed the theory of continental drift based on his studies of similar fossils and rock strata across continents. wegener found a mountain range ending at south africa's coast seemed to align with the edge of a range in argentina, forming a continuous belt. this map displays similarities in fossils found on continents based on wegener's theory. which statement provides additional evidence supporting the scientific conclusion that continents were once joined, but have drifted apart over time?

The sequence of rock layers on Africa's western coast are almost identical to the sequence found on South America's eastern coast, also including a layer containing fossils similar to each other

Explanation:

This is because Geologist Alexander du Toit found layers in both locations to have the following sequence: basalt rock, shale containing fossil reptiles, coal layers containing Glossopteris fossils, rocks containing Mesosaurus fossils, and shale.

it takes hundreds of years to become stable.

if you have another question lmk.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
