The oldest fossil are found in the
Bottom layer
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
Scientist who came after Darwin and cleared up how traits were passed down to offspring.
Mendel
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Darwin was from the 1800's. What part of modern science did he lack knowledge of in order to better explain how traits were passed down from parent to offspring?
genetics
A record of Earth changing over a long period of time
What is fossil record?
Preserved remains of ancient organisms
What are fossils?
This term refers to different traits and alleles within a population.
What is variation?
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
This type of vestigial structure is at the base of our spine
Tail bone
Similarities between the bone structures of paws, hooves, wings, and fins are examples of this.
What are homologous structures?
What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their beaks!
The concept of humans selecting desired traits in species.
What is Selective Breeding?
Structures that have no apparent function and appear to be residual parts from a past ancestor
Vestigial Structures
Why did the population of moths change?
question vary...Need to mention industrial revolution, smoke, trees turning black, the mutated black moths were able to survive and reproduce better and their population grew.
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
Natural Selection
This type of selection selects in favor of the extremes and can sometimes lead to speciation events.
Disruptive Selection
What is one of the 4 steps of Natural Selection
1.Overproduction
2. Genetic Variation
3. Struggle to Survive
4. Successful Reproduction
what is a behavioral adaptation
behaviors
Many of Darwin's major discoveries happened in this location.
What is The Galapagos Islands?
When an organism completely dies out, it is called.....
Extinction

b. animals changed but not plants
c. species change over time by natural selection
c
common ancestors
