adaption
evolution
selection
variation
If scientists were to compare the fossil of a fern that lived millions of years ago with other fern fossils that were formed later, what would they most likely find?
that plants had bones millions of years ago
that plants change over time
that ferns stopped evolving 25 million years ago
that only animals evolve
Which of these answer BEST describes a fossil?
fossils are remains or traces of once-living organisms found in layers of rock or ice, or in amber.
organism from which other organisms are descended.
body of an organism that died recently but has not decomposed
The diagram below shows a portion of the fossil record in sedimentary rock. Different rock layers and fossils are clearly visible.
Layer B contains the second-oldest fossils.
Layer A contains the most recently formed fossils.
The fossils in layer B are older than those in layer D.

Zoology
animals that both have spots
similar organisms that can reproduce
What is the definition of specification
A & D
Similarity in Embryos
the process in which new species were created
formation of distinct species in course of evolution
What is it called when animals alter due to there environment.
Division
Adaptation
Separation
Remains
When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?
Selective breeding
Natural Selection
Cloning
Evolution of all species
Which scientist visited the Galapagos Islands and came up with the theory of natural selection?
Theodor Schwann
Gregor Mendel
Charles Darwin
Rudolf Virchow
A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?
An adaptation
A response to a stimulus
A mutation
Evolution
What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?
There were different types of predators on the island.
There were different types of food available on the island.
The finches had no water to drink.
The finches on the mainland could not fly high enough.
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
This makes an organism more suited to its environment
The pelvic bone of whales is not needed for movement within the water. This is an example of a(n) ______________ structure.
vestigial
analogous
homologous
Brown and green grasshoppers live in a field of green grass. Birds near the field feed on the grasshoppers. Which statement best describes the expected changes in the populations of the brown grasshoppers and green grasshoppers over time in this field?
The populations of brown grasshoppers and green grasshoppers will both increase over time.
The population of brown grasshoppers will decrease more rapidly than the population of green grasshoppers over time.
The population of brown grasshoppers will increase over time, while the population of green grasshoppers will decrease over time.
The population of brown grasshoppers will increase over time, while the population of green grasshoppers will remain constant over time.
