Darwin's theory of natural selection follows some basic assumptions. Select all of the following that describe these assumptions.
Individuals with favorable traits are more likely to survive and reproduce
There will be variations in traits found in a population
Organisms will produce more offspring than will survive
All individuals in a population have the same genetic traits
Which of the following best describes natural selection?
organisms with the worst traits are more likely to survive and reproduce
all organisms have an equal change of survival
organisms with favorable traits are more likely to survive and reproduce
environmental conditions will change over time
Which of the following best describes the relationship between mutations, adaptations, and natural selection?
Beetles with green shells best blend into their environment and survive. The beetle population mutates, so that more beetles are green. This mutation that occurs after surviving means that they reproduce.
A population of beetles does not have genetic variation. The beetles are affected by a selection pressure. Some of the beetles adapt to the change and are able to reproduce and pass their traits on to offspring.
A population of beetles has genetic variation. Some of the beetles possess a mutation that makes them more adapted to their environment. These beetles survive and pass this trait to their offspring.
A population of beetles has genetic variation. Some of the beetles are able to adapt to the changing environment by undergoing mutations, which help them to survive and reproduce.
Which of the following represents natural selection occurring?
the human appendix has shrunk over time because it is not used
a population of rabbits gets larger because wolves are actively hunted by humans
the pelvic bones of whales have grown over time because they no longer need legs
a population of flowers grows all over a meadow because they attract the most pollinators
How can you tell that speciation has occurred?
organisms in a population have variation
populations can no longer reproduce with one another
organisms in populations act differently
populations can reproduce with one another
What would likely occur is a log washed down stream, allowing the rabbit populations to go back and forth from either side of the river?
The two populations have become two different species and would not be able to mate
The two populations would be able to breed even though they are different species
The two populations would share resources and live happily ever after
Based on the image, what type of Isolation is shown?
Geographic Isolation
Behavioral Isolation
Temporal Isolation
Which events would result in speciation? (Choose two)
A mountain range separates two populations of rabbits
Two different species share the same resources in a habitat
Two populations compete for the same resources
Two organisms have different mating behaviors and mate at different times of the year
