Summary Introduction
Introduction:
Fossils are remains of the dead organisms that have been preserved. Paleontology is science that studies these fossils. They are important because they can explain how the evolution of the life we know today had taken place.

RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C.

A. The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them. B. The technology for extracting DNA from fossils hasn't been developed yet. C. The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading D. Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material.arrow_forward
