4.6.2.2 Mutations are changes in the DNA code. They may lead to more evolution, although mutations that result in a new phenotype are rare. Organisms of the same species can interbreed to produce fertile offspring. more likely to survive to breed successfully the genes that have enabled these individuals to survive are then passed on to the next generation. Define the term mutation. Explain why mutation may lead to more rapid change in a species. Define the term species. Identify organisms that are of different species. Interpret evolutionary trees.
