Which statement best describes how mutations are related to evolution? a) there is not a strong relationship between mutations and evolution. b) natural selection causes evolution, which causes more mutations to appear in the dna of the species. c) mutations are changes in dna that produce weaker organisms that die, so these are eliminated by evolution. d) mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

The correct answer is option D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

Mutations are the alterations that occur in the DNA of an organism as a result of replication error or due to environmental factors. Usually, when many such mutations occur in an organism they tend to change the genetic make up of the organism leading to new genes. If these new genes are advantageous for the organism as compared to the old one then a new species tend to evolve. The newly evolved species is better than the old one. For example, such mutations caused homo sapiens to evolve from apes and it is evident that humans are much more evolved than apes.
