Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
He is known as the Father of Evolution
Who is Charles Darwin?

Galapagos
This type of vestigial structure is found at the bottom of our pelvis, indicating a previous presence of a tail
Tailbone
The scientific law that tells us older fossils will be found deeper underground
Law of Superposition
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
A historical sequence of life indicated by fossils found in layers of earth’s crust
Fossil Record
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Populations that are more likely to survive a changing environment need to have lots of ...
variation/ genetic diversity
What is the name of the oldest hominid fossil we have found?
Lucy, Austrelophiticus Afarensis
Preserved remains of ancient organisms
What are fossils?
Humans began to selectively breed plants and animals based on desirable traits, such as larger crop yield or more docile (calm) livestock. What is the term for this process?
Artificial selection
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
What is the name for the ancestors of early humans?
Hominids
A mistake or change that occurs in the DNA sequence is called a ______________________.
What is a mutation?
An organism that walks upright on 2 feet
Bipedal
The concept of humans selecting desired traits in species
What is artificial selection or selective breeding?
According to the modern theory of evolution, new traits are produced by....
What are mutations?
Physical Characteristics that are passed down to the next generation such as hair, eyes, height, weight, etc. Phenotype or genotype.
Phenotype
Pelvic bones in whales are examples of what structure?
Vestigial
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?
What is Natural Selection?
Organs/ structures that no longer serve a purpose and have disappeared or reduced in size
Vestigial Organs/Structures
Whales have flippers, humans have arms/hands, and dogs have legs/paws. These animals have the same bone structure, but they function differently. These are examples of what structures?
Homologous
If the same antibiotic is used too many times, it can become less effective against a certain type of bacteria. This is known as ...
antibiotic resistance
Being able to walk long distances is a benefit of what human trait?
Bipedalism
When an organism completely dies out.
What is Extinction?
Name one evidence of evolution
analagous structures, homologous structures, similar embryos, fossils, DNA analysis
Evolutionists believe that similar organisms evolved from a common ______.
Ancestor
speciation, new species
Study of how embryos develop similarly
Embryology
When one species changes into two or more different species
Speciation
Body structures on different organisms that are similar in function but did not evolve from the same ancestor (bird wing and butterfly wing)
What are Analogous Structures?
While in the Galapagos Islands, Darwin noticed that the Finches' beak shape had evolved based on the...
food source
Natural selection forces individuals to change their DNA to have better traits for survival-- true or false
False
Inherited Characteristics that cannot be seen on the organism such inherited diseases, genetic disorders, etc. Genotype or phenotype.
genotype
