Which of the following statements best explains
the Theory of Natural Selection?
Acquired characteristics of parents can be passed on to offspring.
Organs that are not used may disappear, while organs that are constantly used may develop.
In nature, the organism with desirable characteristics may survive, while those with weaker traits may not.
Organisms develop desirable structures to survive in a given environment.
Which of the following statements explains
Lamarkc,s Theory of Use and Disuse?
Body structures develop because of mutation.
Body structures develop because they are not in use.

Body structures develop because they are used extensively.
He proposed a Theory of Evolution based on Natural Selection.
Jean Baptiste De Lamarck

Doves
Love birds
Eagles
Finches
What point of natural selection states that having many offspring increases the chance that some of them will survive?

Overproduction
He was able to develop three theories which include Theory of Need, Theory of Use and Disuse and Theory of acquired characteristics.
Albert Einstein
Jean Baptiste de Lamarck
Charles Darwin
This revolutionary pattern selects organisms that will or will not survive based on their existing traits. Organisms with favorable traits are those that are best suited to the environment and have a better chance of survival.
Natural Selection
Genetic Drift
Speciation
Is the evolution of morphological similarities in organisms that are not closely related but they have similarities in their habitats, they have similar environmental demands.
Coevolution
Convergent Evolution
Punctuated Equilibrium
Biological fitness is defined as __________.
the ability of an organism to survive and reproduce

the amount of energy an organism can use in the environment
the average life span of an organism
Which of the following is NOT an example of evolution?
Over many generations, wild teosinte has become corn.

Finches in the Galapagos islands have diversified over time into many species each well-suited for eating a particular type of food.
The wings of a bird and the wings of a beetle are considered __________.
homologous structures
analogous structures
vestigial structures
phylogenetic structures
What is a vestigial structure?
A structure that has origins in a common ancestor, but has evolved to perform the same functions
A structure that has origins in a common ancestor, but has evolved to perform different functions
A structure that makes an organism better suited to a habitat
A structure that has lost its function but is still part of the organism
Which of the following is evidence of a common ancestor?

vestigial structures
None of these
How did Darwin's finches help support his theory of evolution?
The finches all lived on different islands
Only the largest birds had survived on the island, while the smaller ones went extinct
The birds were different colors, which allowed for camouflage in different habitats
The size and shape of their beaks varied due to the different environments they lived
Structures that were once functional in the past but no longer serve a purpose due to evolutionary adaptations and physiological changes are referred to as __________ structures.
homologous structures
analogous structures
vestigial structures
None of these
In science, the inheritance of a structure that results from natural selection and by which the organism becomes better able to survive and reproduce is called
mutation
advantage
adaptation
evolution
How do fossils support evolution?
The fossil record provides evidence that organisms have changed over time.
Individual species disappear and reappear in the fossil record over time.

As smaller lizard like reptiles hid in rock crevices to avoid larger predators and feed on smaller insects they found that shorter legs could get further in and find more insects. Over time through many generations snakes evolved as the legs were slowly lost.
