Final answer:
The question focuses on Biology and discusses human augmentation and genetic modification, with CRISPR being a key technology mentioned. Ethical concerns surrounding the use of enhancement technologies in humans, and the implications on genetic variation are discussed.
Step-by-step explanation:
The question pertains to the concept of human augmentation and genetic modification, indicating that we are dealing with the subject of Biology. Human augmentation, in the context of the question, relates to biomedical interventions that enhance human capabilities beyond what is necessary for health. An example provided is the case of Lance Armstrong's 'blood doping.' This form of augmentation remains controversial, as it raises ethical concerns and provides an unfair advantage in competitive sports.
Another facet of human augmentation is genetic modification, which has been revolutionized by gene editing technologies like CRISPR. The advancements in this technology allow modification of genetic material to be more accessible, thereby leading to potential therapeutic benefits and enhancement of human capacities.
When discussing genetic variation within a population, it's important to recognize the value it holds for evolutionary adaptation and overall survival of a species. There's concern that unchecked use of gene editing technologies might lead to reduced genetic diversity, posing a potential risk to human populations.
