What is natural selection?
Q: What is natural selection?
A: Natural selection is the process where organisms with favorable traits are more likely to reproduce. In doing so, they pass on these traits to the next generation. Over time this process allows organisms to adapt to their environment by increasing the frequency of genes for favourable traits in the population.
Q: Who proposed natural selection?
A: Natural selection was proposed independently by the English biologists Charles Darwin and Alfred Russel Wallace in 1858.
Q: What is another name for natural selection?
A: Natural selection is sometimes called "the survival of the fittest".
Q: How does natural selection work?
A: Members of a species are not all alike, partly because of differences in heredity (genetics). This means that some organisms may be better at surviving and reproducing than others in a particular habitat. When this organism reproduces, its offspring may get the genes which gave it the advantage, allowing them to adapt over time to their environment.
Q: Are adaptations always useful in many habitats?
A: Yes, some adaptations are extremely long-lasting and can be useful in many habitats.
Q: Is there any difference between children from same parents?
A: Yes, even with children of the same parents there will be differences due to genetics which can affect how well they survive and reproduce compared to other members of their species.
