What is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time. d.

Which of the following occurred first in the history of life on earth? Colonization of land Evolution of photosynthesis Origin of unicellular eukaryotes Origin of multicellular eukaryotes Origin of prokaryotes
The theory of evolution is supported by a large body of evidence. What is the first occurrence of found in geologic strata?
Which 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) ..
Define the following terms: divergent evolution, convergent evolution, analogous structures, homologous structures
Why was it believed that life began in the seas and not in land or air? * Land and air were inhospitable places for life during the Hadean Eon. Land and air were inhospitable places for life during the Archean Eon. Land and air were inhospitable places for life during the Phanerozoic Eon. Land and air were inhospitable places for life during the Proterozoic Eon.
The dorsal fin of a dolphin (class Mammalia), and the dorsal fin of a shark (class Chondrichthyes), both of which are specializations for vertical stability during high velocity swimming, even though they come from different embryological structures, represent: analogous structures due to convergent evolution homologous structures following convergent evolution analogous structures due to parallel evolution homologous structures following parallel evolution all of the above
