Evolution is best defined as:
the process which organisms die.
the process which organisms change over time.
the process which organisms that are extinct become revived.
the process which non-living things fossilize.
The solidified remain or imprint of a once living thing are called:
Fossils
Homologous Structures
Vestigial Structures
DNA
Adaptations are:
physical or behavioral tendencies.
physical or behavioral traits/characteristics that help an organism survive and reproduce.
physical or behavioral traits/characteristics that do NOT help the organism
genetic mutations that have gone wrong.

A species is defined as:
a group of organisms that are extremely different.
a group of organisms that have similar characteristics and always live in the same place.
a group of organisms with similar characteristics and can reproduce to make fertile offspring.
any two organisms to make a hybrid.
What statement is true regarding why natural selection can be easily seen in insects and bacteria?
Natural selection only occurs in prokaryotic cells
Insects and bacteria can reproduce faster than more complex organisms and pass on selected traits quicker
Insects were the first multi-cellular organism to live on land
Bacteria have directly evolved from insect traits.
Which of the following is true about the picture above?
Camels are highly adapted to cold climates.
There are no benefits to using a camel vs. a horse in the desert.
Camels have directly evolved from whales.
A camels long large intestine, long eyelashes and wide feet allow it to be very adapted to the desert.
When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called.....
Fossils
Extinction
Meiosis
Variations
What do we call a change in a species over time?
Adaptation
Evolution
Extinction
Environmental influences
Birds are eating all the green beetles. Because the brown beetles are surviving they reproduce more and make more brown beetles. This is called ___________
Artificial Selection
The Theory on the Origin of Species
Natural Selection
Mutation
Darwin wrote that the organisms best suited to their environments will .....

Go Extinct
Mutate More often
