Abstract
Continuity is fundamental to life. In multicultural organisms, this continuity is manifested as cells replicate their genetic material (DNA) faithfully and divide to form and maintain a mature individual. Subsequent to conception, single-cell embryos develop into mature individuals made up of trillions of cells that are, for the most part, genetically identical. Except for sperms and ova, which are made up of half the amount of DNA, and some scattered mutations, all the cells in tissues are genetically identical. This is remarkable considering that cells of different tissues look and function differently. Continuity is also evident in how organisms reproduce from generation to generation. Except for the sporadic changes in DNA (mutations), offspring are made up of about half the genetic material of their parents. The process of reproduction is so faithful that parents are immortalized in their children.
