Based upon the conditions of the early Earth, which forms of life most likely appeared first?

• Prokaryotic and aerobic

• Prokaryotic and anaerobic

• Eukaryotic and aerobic

• Eukaryotic and anaerobic

Which statement best describes conditions on early Earth?

• hot with volcanic activity and electrical storms
• dry land covered with volcanic dust
• cold oceans
• dark and dusty with abundant water

Miller/Urey and other scientists studying the origin of life have shown that:

• Formation of life on early Earth required material from space

• Simple cells can be produced in a laboratory using spontaneous generation

• Oxygen and water were present in the atmosphere to support life

• Organic molecules like amino acids and nucleotides could be produced from abiotic/inorganic molecules
