There is not much Precambrian strata preserved and very few species. At this particular time, the earth, and the creatures in it, were still evolving and fossils were difficult to trace and record. There was also a noted mass extinction that occurred. Also, many Precambrian rocks have been heavily metamorphosed<span>, obscuring their origins, while others have been destroyed by erosion, or remain deeply buried beneath Phanerozoic strata</span>

-Medulla in a human is smaller (medullary index of less than one-third); and medulla in animals is very thick (medullary index of one-half or greater).
- Cuticle in humans is imbricated; and the cuticle in animals is coronal or spinous.

The hallmark of our species, according to evolutionary psychologists is OUR ENORMOUS CAPACITY AND OUR SHARED BIOLOGY ENABLED OUR DEVELOPED DIVERSITY.
Evolutionary psychology is the study of the root of behavior and mental processes using the process of natural selection and focusing on what make human beings alike. Evolutionary psychologist believed that human beings are so very much alike because they have the same biological make up and high capacity.
DNA polymerase is the enzyme that catalyzes the base pairing during DNA replication.
The DNA polymerases are enzymes that synthesize DNA molecules by assembling deoxyribonucleotides, the building blocks of DNA. These enzymes are essential to DNA replication when they read the existing DNA strand to synthesize new strand that match the existing ones by adding nucleotides to the three prime (3')-end of a DNA strand.
