Textbook Question
Chapter 26, Problem 3A
Which bits of evidence would convince you that life originated as early as 3.2 BYA?
a. You look at a microfossil under a scanning electron microscope and it is the same shape as a cell.
b. A high-quality transmission electron micrograph of a fossil cell reveals cellular compartments, including a possible nucleus.
c. Potassium dating of a fossil containing a possible cell indicates that the fossil is 3.2 billion years old.
d. Using transmission and scanning electron microscopy, you find evidence of a carbon-based material in what appears to be a cell wall of a fossil isotopically dated as 3.2 billion years old.

The Earth's amino acids were from a 4.5 billion years old meteorite C. Inorganic compounds created organic compounds spontaneously D. Inorganic compounds were results of lightning and UV radiationarrow_forwardWhy can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? 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_forwardWhich of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. 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. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..arrow_forward
