The New Genetically Modified Humans

For more than 100 years, athletes have striven to complete the marathon in less than two hours. Now scientists believe that advances in genetics could lead to a runner completing the 26.22mile course in 90 minutes. After a series of laboratory breakthroughs they claim that bio-engineering techniques could be used to create a superhuman long-distance runner. The scientists claim that modifying the human genome could, in theory, increase the size of an athlete’s heart, boost the number of red blood cells supplying the body with oxygen and increase the endurance of specific muscles by up to 10%.
