Vertebrate embryos:
Have similar stages of development, due to a common ancestor
Have different stages of development, due to a common ancestor
Tetrapods (4 limbs) have very similar bone structures. This leads biologists to believe:
They all had a common ancestor
Their common ancestor was probably a lamprey
Their limbs are convergent evolution
Which is artificial selection?
Breeding dogs for specific traits.
Coyote species diverging from the wolves.
Natural selection would select for:
Better camouflage for hiding
Bigger, redder, neck sack to attract females.
Bigger antlers to beat up other deer.
Loss of alleles.
An animal has several inherited characteristics that makes it much fitter than its rivals. According to Natural Selection it should:
Help the others that are less fortunate
Survive longer, have more and better babies.
Be equals with its kin
A species of spider is an average of 5 cm long. Any longer and it has trouble hiding from birds. Any smaller and it has trouble catching prey. What type of selection is this?
Stabilizing
Directional
Disruptive.
Genetic variation in a population can be increased with:
Mutations
Genetic drift
Founders effect
Genetic bottleneck.
High fitness individuals in a population:
Live longer and have more offspring
Live longer but have less offspring
Neither live longer nor have more offspring
Individuals who enter or leave a population, taking their alleles with them are contributing to:
Gene flow
Genetic Bottleneck
Founder effect
The picture shown is an example of
Vestigial structures
Homologous structures
Analogous structures
Fossils
Which process of evolution is demonstrated below?
Comparative anatomy
Homologous structures
Comparative embryology
Vestigial structures
Which evidence for evolution is shown below?
Comparative embryology
Homologous structures
Biochemical evidence
Vestigial structures
See picture for question
Live in the same type of ecosystem
Have slowly evolved to become herbivores
Have a common ancestor
Exchanged DNA at some point in the past
The bones in the figure above are-
Evidence of a common ancestor
Evidence that animals can walk
Evidence that fossils are old
Evidence of nothing
Genome maps provide the DNA sequences of chromosomes. Some scientists have compared the genome maps of a hedgehog and a sloth. What do these genome maps allow the scientists to determine?
The color patterns of the offspring of each species
How much the size ranges of the two species differ
The methods of protein synthesis that each species uses
How closely related the two species are to each other.
What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones?
The ancestors of whales may have been land mammals
Whales could walk if they wanted to
Whales are preparing to evolve into land animals
Someday whales will be able to walk and will have legs
Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. If the scientists do further biochemical analyses, which additional finding would support this conclusion?
The fossils of both organisms are found relatively close to each other in the fossil record.
The anatomical structure of both organisms is similar.
The DNA nucleotide sequence of both organisms is similar.
Both populations of organisms have undergone natural selection over time.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they-
Belong to the same species
Must range great distances to eat
Have very similar skeletal structures
Are descended from a common ancestor
How can the pattern of change in the fossil record best be explained?
The mollusks were well adapted to their stable environment. A large, sudden change occurred in their environment. After the change the mollusks with the bigger shells were better adapted for the new environment.
The mollusks were well adapted to their stable environment. The mollusks hybridized with a smaller species of mollusk. A new species of mollusk with a bigger shell resulted.
The mollusks were not well adapted to their environment. The length of the mollusks' shells changed gradually over time. The mollusks in the original population that had small shells died over a period of many years.
The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them —
Individuals can not evolve.
Darwin's Finches became separate species due to
Geographic isolation
Temporal Isolation
Behavioral Isolation
Postzygotic Isolation
The term for the formation of new and distinct species over the course of evolution is...
speciation
biological species concept
reproductive barrier
natural selection
