Descent with modification
Change in the genetic composition
Natural selection
Survival of the fittest
Aristotle's concept of 'scala naturae' is best described as:
A hierarchical structure of all matter and life
A theory of evolution
A mathematical model
A political philosophy
According to the Hypothesis of Evolution, what happens to parts of the body that are used extensively?
Parts of the body that are used extensively become stronger and more developed.
Parts of the body that are used extensively become weaker and less developed.
Parts of the body that are used extensively remain unchanged.
Parts of the body that are used extensively disappear over time.
1st Principle: Use and Disuse. If plants gradually grow taller, eventually making it difficult for the giraffe to reach its food, what will the animal do?
The giraffe will grow a longer neck to reach the food.
The giraffe will find food on the ground.
The giraffe will move to a different area with shorter plants.
The giraffe will stop eating and starve.
According to the Principle of Disuse in the Hypothesis of Evolution, what happens to a fish in a low light environment?
It gains a better sense of sight.
It loses its sense of sight.
It develops a new sense.
It remains unchanged.
What is the title of the book published by Darwin on November 24, 1859?
Two variation of giraffes living in an environment with a lot of tall trees. What will happen to the two species of giraffes after some times?
Long-necked species will thrive as its trait is fitted with the environment
Short-necked species will thrive as its trait is fitted with the environment
Both species will thrive equally
Neither species will thrive
Fill in the blank: Inheritable traits that ______ the survival rate of the organism will be passed over generations.

Which of the following best describes the concept of 'survival of the fittest'?
Only the strongest individuals survive.
Survival is based on random chance.
Individuals best adapted to their environment survive and reproduce.
All individuals have an equal chance of survival.
How does the environment influence the process of evolution?
It prevents any changes in species.
It causes all species to evolve in the same way.
It has no influence on evolution.
It determines which traits are advantageous.
The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...
homologous structures
vestigial structures
transitional fossils
common ancestors
The two most important things that the fossil record tells us about the history of life on Earth are...
some species go extinct, and it is impossible for new species to take their place
some species go extinct, and new species appear over time
species usually never go extinct, but somehow dinosaurs did go extinct
Earth never changes, and changes to life on Earth happen very quickly
A bird's wing and a butterfly's wing have the same function, but they have very different structures. These structures are classified as follows:
homologous structures
analogous structures
vestigial structures
embryological homologues
The process by which populations slowly change over time is called
selective breeding
adaptation
speciation
evolution
Which of the following would be an example of homologous structures?
the trunk of an elephant, the snout of a pig, and the nose of a dog
the wings of a bat and the wings of a butterfly
the tale of a dolphin and the hump on a camel’s back
the arm bones of an ape and the front leg bones of a horse
The tail bone, wisdom teeth, and appendix are all parts of the human anatomy that would be considered..
homologous structures
vestigial structures
fossils
extinct
If species A and B have very similar genes and proteins, what is probably TRUE?
species A and B share a relatively recent common ancestor
species A evolved independently of species B for a long period
species A is younger than species B
species A is older than species B
Which of the following options is NOT one of the main pieces of evidence of evolution that we have studied in class?
The Fossil Record
Embryology
Comparative Anatomy
Cosmology
What is the term for a structure that has lost its original function through evolution?
transitional fossil
homologous structure
vestigial structure
analogous structure
Which of the following is an example of natural selection?
Scientists creating genetically modified crops
Birds with longer beaks surviving better in an environment with deep flowers
Animals being trained to perform tricks
Farmers breeding cows for higher milk production
