Which of the following can be determined by observing the embryos shown in the diagram
Vestigial structures
structures that perform a similar function but are not similar in origin
remnants of once-important structures that have slowly lost all or most of their function
features found in different organisms that share structural similarities but may have very different functions
preserved remains of an organism
The picture shows a/an ___________
homologous structure
vestigial structure
What is this an example of?
Homologous structure
Analogous structure
Vestigial organs
Functional adaption
What best describes the hind leg bones seen in the whale?
The bones are analogous structures to the fins of living fish.
The bones are vestigial structures that had a function in an ancestor.
The bones are homologous structures to the wings of butterflies.
The bones are fossil structures from an extinct ancestor.
_______________, or selective breeding, is one way that humans impact evolution. One example is how the Belgian Blue cow has been bred to have greater muscle mass.
Artificial selection
Homologous
Scientists are studying a particular protein found in blood cells. Based on this, which animals are most closely related?
Dog: ARG - LYS - HIS - TYR
Rabbit: ARG - LYS - TYR - TYR
Elk: ARG - PRO - TYR - ARG
Dog & Rabbit
Rabbit & Elk
Dog & Elk
This makes an organism more suited to its environment
species
lifespan
adaptation
mutation
Evolution
Natural Selection
Extinction
Artifical Selection
the best adapted
the fastest
the strongest
the most domesticated (tamed)
The light mice can reproduce more successfully than the dark mice
The hawks eat more dark mice than light mice because the dark mice taste better
The hawks eat more light mice than dark mice because they can see the light mice more easily
The hawks eat more dark mice than light mice because they can see the dark mice more easily
Natural Selection
Variation
Homeostasis
Extinction
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the organism knew it needed that trait, survives, and passes it on.
Mutations are a change in what?
DNA
tRNA
protein
rRNA
Where do adaptations come from?
The individual organism decides to adapt
Mutations that give an organism an advantage in its environment
Genetic recombination during meiosis
Both mutations and genetic recombination are sources of adaptation
Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
changes in genotype, but not phenotype
Another term for Natural Selection is:
Breeding
Commensulism
Communism
Survival of the fittest
Which of the following represents genetic drift?
Which of the following represents gene flow?
the movement of genes into or out of a population
Gene Flow
Random chance; small population
Genetic Drift
A sudden change in one or more characteristics due to a change in a gene
Mutation
Occurs due to physical difference as a result of a genetic difference
Non-Random Mating
The movement of organisms from one place to another
Migration
Which of the following does not show genetic drift?
Species show very little evolutionary change in the fossil record
Stasis
Natural Selection
Artificial Selection
Darwinsim
Evolution occurring gradually and slowly over long periods of time
Homeostasis
Stasis
Punctuated Equilibrium
Gradualism
Evolution occurring quickly due to catastrophic events
Homeostasis
Gradualism
Statsis
Punctuated Equilibrim
Two populations of the same species are separated by land barriers like rivers or mountains.
geographical isolation
temporal isolation
adaptive ratiation
behavioral isolaton
Two populations of the same species do not have the same mating rituals or signals.
geographical isolation
temporal isolation
adaptive ratiation
behavioral isolaton
The frequency that single genes (alleles) for a trait appear in a population.
Genome
Gene frequency
Genetic Drift
Population Frequency
Organisms of the same species can no longer interbreed therefore creating two species.
Gene Pool
Genetic Drift
Gene Frequency
Speciation
Severe population reduction reduces the gene pool
and increases the rate of genetic drift. Woolly mammoths became extinct. Elephants survived.
Gene Pool
Bottleneck Effect
Founders Effect
Gene Frequency
Isolated small populations speed up genetic drift.
Gene Pool
Mitosis
Speciation
Founders Effect
Natural selection affects _______________
