Geological events, like continents breaking up and mountains forming, may lead to...
extinction of several species.
evolution of several species.
certain species being dominant.
Geological events may affect all of these.
Which idea did not influence Darwin's Theory of Evolution?
Gradualism
Uniformitariansim
Natural Selection
Genetics (DNA)
Which of the following represents the shift in thinking that was occurring when Darwin was developing his theory of evolution?
Uniformitarianism --> Natural Theology
Catastrophism --> Gradualism
Lamarkian Evolution --> Darwinian Evolution
Taxidermy --> Taxonomy
What was the main problem with Lamarck's evolutionary theory?
Individuals acquired traits from the evolutionary process, which in turn, was passed on to offspring.
Populations that failed to adapt to new environments still evolved.
Some groups within a species never passed their traits on to the next generation.
Individual species adapted to their environment, they then passed those adaptations to offspring.
The generation to generation change in a gene pool is referred to as...
Linear evolution
Macro-evolution
Micro-evolution
Branching evolution
An individual organism uses a physical trait or structure, that they already possess, to aid in their survival in a new environment. The organism is said to have...
Adapted to its new environment.
Evolved to better fit its surroundings.
Which of the following is an example of a behavioral adaptation?
Predators hunting at night to catch sleeping prey.
Predators that have the ability to change their coloration with the seasons, in order to blend in to their surroundings.
Predators using their claws to dig for roots, since their are no more prey animals in their environment.
Predators with longer snouts using those snouts to better reach food sources that are in small crevasse.
The main difference between Micro-evolution and Macro-evolution is...
Micro-evolution is directly observed and Macro-evolution is not.
Macro-evolution creates new species, Micro-evolution does not (directly).
Both of these statements are correct
Both of these statements are incorrect
How do small population sizes lead to micro-evolution (i.e. change in a gene pool)?
Removing individuals in a small population removes their genes as well.
In small populations, there is an increased change of inbreeding.
Small populations are more likely to have a change in the gene pool of the next generation, simply due to chance.
All of these are ways small populations lead to micro-evolution.
How does isolation lead to micro-evolution (i.e. change in a gene pool)?
Cutting off flow of genes from the larger population doesn't allow the genes to distribute evenly to both populations.
Individuals in each population adapt to different surroundings, this causes the two populations to evolve to fit their new surroundings.
When isolation occurs with small populations, the chances for inbreeding increase. This can increase the number of abnormal genes.
All of these are ways isolation can lead to micro-evolution.
How does nonrandom mating lead to micro-evolution (i.e. change in a gene pool)?
Individuals in a population may select mates that possess a desirable trait. The genes that code for this trait increase in the population in the next generation.
Males within a species may compete for the females through physical contests. Males that win these confrontations mate with all the females in the population, passing his genes on to the next generation.
Females within a species may select a male that can perform a mating ritual (e.g. dance) better than his competitors. Males that perform the best, have a better change of mating and passing on their genes to the next generation.
All of these are ways nonrandom mating can lead to micro-evolution.
How does natural selection lead to micro-evolution (i.e. change in a gene pool)?
Prey that is camouflaged avoids being eaten by predators more often than prey that isn't. Camouflaged prey will pass more genes on to the next generation.
Plants that are more tolerant to a warming climate produce more seeds than plants that are not. The heat-tolerant plants increase the number of genes in the gene pool.
One predator out competes another predator (of the same species) for land and resources. The more successful predator contributes more genes to the gene pool in the next generation.
All of these are ways natural selection can lead to micro-evolution.
The end result of macro-evolution is believed to be...
extinction
speciation
adaptation
nothing - no change.
Closely related species that look very different as a result of using an existing physical structure to become better suited to their respective niches in the environment.
Adaptive Radiation
Macro-evolution
Micro-evolution
Speciation
The BIG IDEA of this section of the Earth History Unit: Organic Evolution is...
There are more than one type of evolution: micro-evolution and macro-evolution.
Life responds to Earth's physical structures and processes.
Individuals of a species adapt and populations of species evolve.
Darwinian evolution is right and Lamarckian evolution is wrong.
