have the ability to interbreed.
Based on Darwin's findings, what determines an organism’s ability to survive?
Its ability to have babies
Its ability to adapt to the environment
Its ability to move out of a bad environment
Its ability to win competitions
The formation of a new species is called
Natural selection
Struggle for existence
Speciation
Darwinism
When HUMANS select or choose a plant or animal for breeding based on a desired trait
natural selection
artificial selection
Parts of the body that are similar to other species because they have a common ancestor
fossil record
homologous structures
embryology
Shows how different groups of organisms have changed over time.
fossil record
homologous structures
embryology
Body part you have that use to have a purpose but now has little or no function
vestigial organ
embryology
homologous structures
Fossils record
Similarities in Early Development
Structures within organisms
All of the Above
The light mice can reproduce more successfully than the dark mice
The owls eat more dark mice than light mice because the dark mice taste better
The owls eat more light mice than dark mice because they can see the light mice more easily
The owls eat more dark mice than light mice because they can see the dark mice more easily
What is a phylogenetic tree?
an idea that is strongly supported by evidence and facts.
an inherited characteristic that increases an organism’s chance of survival and reproduction in an environment
“hand-picking” traits to be bred within a species to create a “race” of desirable organisms
a diagram that represents evolutionary relationships among organisms
The tundra is a vast plain with frigid temperatures and plenty of snow. Which of the following adaptations does not help the polar bear survive in the tundra.
Layers of fat for insulation
webbed toes for swimming
white fur for camouflage
total herbivorous diet
On the Galapagos Islands, different finches evolved on different islands to fit their environment. When a species develops unique traits because it is trapped in one area this is called:
Geographic isolation
Geologic separation
General relocation
Genetic differentiation
Which of the following is NOT true in the formation of a new species?
A mutation causes a population to breed with a different species.
Reproductive isolation can occur by the formation of a mountain range.
A population needs to become reproductively isolated.
An isolated population has adapted to new ecological niches eventually result in the inability to reproduce with the original population.
Homologous structures are bones or organs found in different animals which very closely resemble structures in different organisms. What can you conclude about the past of these organisms?
They all have evolved through natural selection but do not use these structures anymore.
They all share a common ancestor but have evolved through natural selection
They all share a common ancestor but did not evolve from natural selection
The evolution of the horse is the most complete fossil record we have of a single organism. Using the picture, what can you conclude happened to the horse over time?
The horse grew larger and lost its toes
The horse shrank and lost its toes
The horse grew larger and gained toes
The horse shrank and gained toes
Fossils are proof of ___________.
Evolution
analogous structures
Physics
artificial selection
