Mutations are believed by many evolutionists to provide a means for variablity in some of the characteristics of a species. For example, extra fingers and toes. However, since all mutations are DNA-destructive and result in a loss of information, increasing complexity from mutations is believed by many to be impossible. This is especially true if one subscribes to Information Theory, which states that information only comes from greater pre-existing information. Extra fingers only demonstrate an error in creating the correct number of digits, not additional information.
If a certain variation provides an advantage for an individual (or inter-breeding group) they these individuals will survive and breed where all others will die. This is natural selection (not evolution). The offspring of the survivors will all carry the traits of their parents. Therefore, the fittest will tend to thrive, but not change into a different species, at least not through this mechanism.
What else can I help you with?
What best describes how a species changes over time?
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.
What concept of evolution explains why organisms are constructed to meet the demands of their environment?
Natural selection explains adaptive change in the immediate environment.
Compare and contrast natural selection and evolution?
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
What are the two theories for which Charles Darwin is known A.Evolution and natural selection B.Psychoanalysis and the unconscious C.Evolution and socialism D.Natural selection and psychoanalysis?
A. Evolution and natural selection. Charles Darwin is primarily known for his theories on evolution, which explains how species change over time, and natural selection, which is the process by which advantageous traits become more common in a population.
What is the idea that species originate through a gradual change of adaptations?
The theory of evolution by natural selection. Called gradualism.
How does the process of natural selection contribute to the evolution of species in biology?
Natural selection is a key mechanism in evolution where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this process leads to the gradual change and adaptation of species to their environment, resulting in the evolution of new species.
What best describes how a species changes over time?
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.
What 2 factors determine the evolution of a species?
Two key factors that determine the evolution of a species are genetic variation and natural selection. Genetic variation provides the raw material for evolutionary change, while natural selection acts on this variation by favoring individuals with traits that increase their chances of survival and reproduction.
What was Darwin's belief about the origin of species?
After observing nature for some time, Darwin came to believe in natural selection causing a change in the evolution of species.
What is the relationship between evolution and natural selection?
Evolution is the process of change in species over time, while natural selection is a mechanism by which evolution occurs. Natural selection acts on genetic variation within a population, favoring traits that increase an individual's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
Which scientist proposed a theory about how evolution works?
Charles Darwin proposed the theory of evolution by natural selection in his book "On the Origin of Species." This theory explains how species change over time through the process of natural selection acting on heritable variations.
Organisms stay the same due to evolution natural selection and artificial selection. true or false?
False. Organisms change over time due to evolution, which is driven by natural selection (survival of the fittest) and artificial selection (human intervention). This process leads to the adaptation and diversification of species.
What is the difference between evolution and theories of evolution?
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
What is the best definition for the concept of evolution?
Evolution is the process by which different species of organisms develop and change over time through genetic variation and natural selection, leading to the emergence of new species.
