The "law" of faunal succession:
a. was developed by theoretical biologists to explain evolution.
b. was passed in congress to dictate equal teaching of different theories of origins.
c. was developed by an engineering geologist to aid in construction projects.
d. requires that evolution occurred.
e. requires that evolution was a catastrophic process.

Option D, Requires that evolution occurred

Explanation:

As per the law of Faunal Succession, the strata in a sedimentary rocks consists of fossils of different time period that are arranged one over the other in a vertical manner. This shows that each vertical layer consist if fossils that have evolved from the previous fossilized species.

This was found by  geologist William Smith who later used this vertical strata for determining the age of rock and sediments based on the rock of fossils.

Hence, Option D is correct

the correct answer is sex-linked recessive.

i just took the test

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
