很早以前就已发现,动物的运动能力有明显的遗传性。例如在欧州通过对二十代马的跟踪研究证明,在所有赛马中取得最好成绩的始终局限在三种名马之中。这说明马的奔跑能力有稳定的遗传性。对人的家系追踪也发现了人的运动能力与遗传也同样是密切相关的。
It has been discovered long ago that the ability of animals to exercise is obviously hereditary. In Europe, for example, the follow-up study of 20 generations of horses proved that the best result in all horse racing was limited to three kinds of names. This shows that the horse’s ability to run a stable heredity. Tracing people’s family also found that people’s motor ability and genetics are also closely related.
