What does antibiotic resistance and pesticide resistance have to do with evolution?
When antibiotics and antibiotics are used frequently, the populations evolve a natural immunity to them. this is best explained by Darwin's theory of survival of the fittest, individuals with the best-adapted traits will be the only ones to survive, reproduce, and pass on their traits.
What are the conditions of natural confitions?
Natural selection is a process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully, leading to evolutionary changes in populations over time. It results from variation in traits among individuals, heritability of those traits, and differential survival and reproduction based on those traits.
What traits help the slug survive?
llolo
The traits of individuals best adapted to survive become more common in each new generation because?
Offsprings without thoes traits do not survive.
How do populations evolve?
Populations evolve mainly in two ways: By natural selection and genetic drift Natural selection is the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations. Genetic drift is random changes in the frequency of alleles in a gene pool, usually of small populations.
Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
In nature what is responsible for creating new traits?
Evolution
The change in the inherited traits of populations of organisms over time is known as?
It is called genetic drift.
How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
