100
The process in which a species has changed over time is known as this.
What is evolution?
100
He is known as the Father of Evolution
Darwin
100
The ability of an individual to survive and reproduce is known as this.
What is biological fitness?
100
What can similar bone structures in different animals suggest?
They may share a common ancestor.
100
A mistake in the genetic code of a section of DNA is known as a (also how new adaptations form) ______________.
mutation
200
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
Homologous Structures
200
A change that increases an organism’s chances for survival is a(n):
Adaptation
200
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
200
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 and DNA
200
Do individual organisms evolve during their lifetimes, or do populations evolve over generations?
Populations evolve over generations.
300
Preserved remains of ancient organisms
What are fossils?
300
The concept of humans selecting desired traits in species.
What is Artificial Selection?
300
The concept that organisms who are the best suited to their environment will be the most successful
What is survival of the fittest?
300
This is a type of structure that was once used in a species, but has since evolved to be of no real use.
vestigial structure
300
What is the process by which a species permanently disappears called?
Extinction
400
What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their beaks!
400
The concept that members of each species are seeking the same food, space, and other necessities is known as this.
What is competition?
400
Structures with similar functions but are not similar in origin like a butterfly wing and a bat wing. These are not proof of a common ancestor but proof that evolution can occur
Analogous Structures
400
What might happen if an organism cannot adapt to changing environmental conditions?
Its population may decrease or become extinct.
400
When fossils are found in the same rock strata, or layer, what does that say about the organism?
They died at the same time
500
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
500
What happens to helpful inherited traits over many generations?
They become more common in the population.
500
Which fossils are generally older: those in deeper or shallower undisturbed rock layers?
Deeper rock layers
500
How are inherited traits passed from parents to offspring?
Through genes or DNA
500
How old is the Earth theorized to be?
4.54 billion years old
600
The "parent" species from which two or more separate species evolved is known as _____________.
C - common ancestor
600
According to natural selection, organisms better adapted to their environment will:
survive and reproduce at a greater rate
600
The embryos of different organisms look similar because...
the developed from common ancestors
600
What are the 3 of the 5 evidences of evolution?
Structures, DNA, Fossils, Embryos, and geography
600
: Explain how natural selection caused the peppered moth population to change over time.
During the Industrial Revolution, soot darkened tree bark, making dark peppered moths harder for predators to see. Dark moths survived and reproduced more, so they became more common. After pollution decreased, lighter moths became more common again because they were better camouflaged on lighter trees.
700
Which information can best help scientists determine if two different organisms are members of the same species?
the physical structures of the organisms
700
This term refers to different traits within a population. (Example: The different beaks of Darwins finches)
What is variation?
700
The bones of this ocean animal (mammal) have been examined and theorized that their ancestors at one time walked on land. They are distantly related to the hippopotamus.
What is a whale?
700
What are 2 of the 5 mechanisms of evolution - how have organisms been able to change
Gene flow, non-random mating, mutation, small population size, natural selection/adaptation
700
_________ describes evolution toward similar traits in unrelated species, like when animals look white and have lots of fur or fat in the Artic.
Convergent evolution
