CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology that allows for precise modification of DNA sequences in living organisms. It has transformed fields such as medicine, agriculture, and biotechnology by enabling targeted genetic alterations.
Evolution is the change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. The theory of evolution by natural selection, first formulated in Charles Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
