Which example best illustrates a condition necessary for natural selection to occur?
Cheetahs have nearly identical genetic makeup. Clownfish can lay a thousand eggs at a time. Some bacteria have very specific temperature requirements
.
Which condition is essential for natural selection?
Four conditions are needed for natural selection to occur:
reproduction, heredity, variation in fitness or organisms
, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Which of these best illustrates the concept of natural selection?
Which of the following best illustrates natural selection? –
An organism with favorable genetic variations will tend to survive and breed successfully
. … This answer represents evolution as a whole, not the process of natural selection.
Which conditions are necessary in order for natural selection to occur on a given trait in a population quizlet?
In order for natural selection to occur, three conditions must be met:
There must be variation for the particular trait within a population
. The variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).
Which is the best example of natural selection?
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example,
treefrogs
are sometimes eaten by snakes and birds.
What are the 4 factors of natural selection?
Construct an explanation based on evidence that the process of evolution primarily results from four factors:
(1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the

How do you explain natural selection?
Natural selection is the
process through which populations of living organisms adapt and change
. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
The theory of evolution by natural selection means that the inherited traits of a population change over time. … Inherited traits are
influenced by genes
, which are passed on to offspring and future generations. Things not influenced by genes are not passed on to your offspring.
Which best describes the relationship between evolution and natural selection quizlet?
Which best describes the relationship between evolution and natural selection?
Natural selection leads to evolution. Evolution leads to natural selection
. Natural selection is the same as evolution.
What are the three conditions of natural selection?
The essence of Darwin’s theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for
existence, variation and inheritance
. These are said to be the necessary and sufficient conditions for natural selection to occur.
Which of the following are possible outcomes of natural selection?
The two most extreme outcomes of natural selection for species are
extinction and speciation
. Natural selection may cause populations of species to change, but exactly how they change depends on the specific selective pressures at a given time.
Why are misunderstandings of how natural selection works so common quizlet?
Why are misunderstandings of how natural selection works so common?
The application of terms like “survival of the fittest” to business or social situations, where individuals can change, leads
to misunderstandings about natural selection, where only populations change.
How does natural selection affect us?
Probably more than you might think, a new study suggests. Natural selection
is still influencing the evolution of a wide variety of human traits
, from when people start having children to their body mass index, reports a study published Monday in the journal Proceedings of the National Academy of Sciences.
What are the 5 types of natural selection?
Stabilizing selection, directional selection, diversifying selection, frequency -dependent selection, and sexual selection
all contribute to the way natural selection can affect variation within a population.
Is genetic drift an example of natural selection?
Genetic drift affects the genetic makeup of the population but, unlike natural selection, through an
entirely random process
. So although genetic drift is a mechanism of evolution, it doesn’t work to produce adaptations.
