The early atmosphere of Earth was largely composed of this
What is steam?
This process can result in evolution over time
What is natural Selection?
This type of structure is the remnant of another structure that was once beneficial, but no longer serves a purpose
What is a vestigial structure?
These are the three parts of a molecule of DNA
What are a 5 carbon sugar, phosphate group, and a nitrogenous base?

What are deep sea vents?
This event resulted in the diversification of life about 540 million years ago
What is the Cambrian Explosion?
This process can occur if a large population is greatly reduced, and then recovers. It often results in inbreeding

What is an insertion?
This theory, popular for a long time, suggested that living things could arise from non-living matter
What is the theory of abiogenesis?
This era is noted for the dominance of the dinosaurs
What is the Mesozoic era?
This theory has five conditions that must be met in order for genetic equilibrium to exist
What is the Hardy Weinberg theory?
This theory suggests that some organelles started out as prokaryotic organisms living symbiotically with our ancestral cells
What is the endosymbiont theory?
The number of hydrogen bonds holding each pair of nitrogenous bases together
What are 2(adenine -thymine), 3(cytosine-guanine)?
Particles of this mineral might have served as templates for the first genetic material
What is clay?
The first living organisms on Earth were most likely these two things
What are autotrophic and prokaryotic (also accept unicellular)
a type of speciation where the ancestral species lives side by side with the newly evolved species
What is sympatric speciation?
Daily double
What is 16%

Daily Double
large population, no immigration or emigration, mating is random, no mutation, no natural selection
When two organisms evolve together
What is coevolution?
