...form of chromosomes. Since chromosomes come from both parents, this nuclear DNA is reshuffled with each generation, confusing the line of inheritance. But there is also DNA outside the nucleus, in mitochondria, substructures within each cell that are responsible for producing energy the cell needs. Since the sperm's mitochondria do not survive fertilization intact, mtDNA is inherited solely through the mother. The only way it can change over the generations is through mutation. And that mutation, evidence suggests, proceeds at a steady, known rate. To calculate how much time has elapsed since the mutations that gave rise to today...
...number of schools, sex education turns out to be nothing more than a brief bout with a safely biological "swimming sperm and Fallopian tube" course that has put students to sleep for generations.

Its sales have increased dramatically, mainly because of the fear of sexually transmitted diseases, particularly AIDS and herpes. No longer hidden behind drugstore counters, condoms are openly displayed on self-service racks. The customers have changed too. Today women buy at least a third...
...nothing so extraordinary; some 2,000 children conceived outside the womb have been born since 1978. But this particular little girl was born to a woman who is not her mother. Last summer a woman who could not carry a child had an egg fertilized by her husband's sperm in a laboratory. The embryo was then transferred to the womb of another woman...
