What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
How has the natural selection harmed the ecosystem?
It hasn't. Natural selection is a key part of the ecosystem itself.
What does natural selection have to do with biodiversity?
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.
Which of the following organisms likely evolved by natural selection?
Dolphins.
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
All of these terms EXCEPT contribute to natural selection?
Genetic drift, as it is a random process that does not necessarily contribute to the differential survival and reproduction of individuals. Variation, heritability, and differential reproductive success are essential components of natural selection.
The molecular and structural similarities observed among these organisms is best explained by which of the following?
natural selection
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
What are 3 basic components to today's theory of evolution?
Three basic components of today's theory of evolution are genetic variation within a population, natural selection acting on this variation, and the inheritance of traits that confer a survival or reproductive advantage.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
What is the prefix and suffix of natural selection?
The prefix of natural selection is "natural" and the suffix is "-tion".
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
The mechanism by which organisms evolve is known as?
Natural Selection
What principles includes variation and competition?
Natural selection.
