The first step in natural selection is a mutation. What is a mutation?
change in population
a growth spurt
change in DNA
an extinction of part of a species
What is an adaptation?
a trait that helps an organism survive its environment
when an organism cannot compete and dies out
when an organism turns into a fossil
a trait that causes an organism to compete for the same resources
When you have a variation in a species and one of the traits is favorable, helping it survive in an environment and the other variation cannot compete and dies out is called?
natural selection
competition
parasitism
commensalism
Which of these scenarios would increase the likelihood for an organism to become a fossil?
being buried quickly and deeply
increased presence of scavengers
weathering and erosion
being buried in igneous rock
How do scientists know about the history of life on Earth?
by studying rock layers and the fossil record
human beings were the first life form on Earth
by studying volcanoes
by measuring the amount of tectonic plates move each year
What do scientists study to prove the theory of evolution?
homologous structures, fossil record, vestigial structures and embryology
homologous structures, environment, and rocks
homologous structures, mutations and mass extinctions
mutations, natural selection, finches and embryology
What is true about these homologous structures?
They have different structures but all perform the same function or task
They all have similar structures but each has a different functions

Which of these events connected with an asteroid striking Earth would have the MOST impact on living organisms?
A crater nearly 2 km in diameter forms in the middle of a grassland.
The collision throws a massive cloud of dust into the atmosphere which blocks the sun.
A wildfire start and burns an area 4 km around
The crash of the asteroid is heard from 75 km away.
Absolute age is defined as:
The exact age of a rock or fossil.
The age of rock based on living animals.
The age of rock based on its location.
The estimated age based on using index fossils.
