Researchers have developed a new method to estimate the lifespan of humans by analyzing their DNA. DNA is the layout of our body structure and can provide us all the information regarding aging and lifespan. Researchers performed genetic studies on various species to collect information about their lifespans. Based on DNA studies, researchers figured out that modern humans have a “natural” lifespan of around 38 years. Though, the human race can be considered as an exception to this study due to continuous advancement in medicine and lifestyle which has increased the average lifespan. Researchers considering this method impactful for several species that are seeking better wildlife management.
