The Evolution of Life Expectancy and C.R. Bard

According to data from the Central Intelligence Agency of the United States, the world average life expectancy in 2010 was 67.2 years. This figure is more than twice the life expectancy at birth at the beginning of the 20th century and is reported as 31 years old. Increased life expectancy is a direct result of accelerating and dramatic progress in medical advances in the early and late 20th century. A deeper understanding of disease diagnosis, treatment, and treatment is the result of frequent cross-over progress in biology, chemistry, microbiology, physiology, pharmacology, and medical technology.

The medical and scientific community is increasingly paying attention to the medical and scientific community and in particular considering how rapid development of medical devices has lengthened the average life span over the past two decades, technology "cures" the aging process be able to. The average life expectancy doubled since 1900, reaching 71.4. The modern implementation of the first stethoscope in 1815, the X ray of 1895, the pacemaker of 1936, the mechanical heart of 1952, the DNA sequencing of 1992, and the visually impaired bionic eye are all broader It was innovation. An example.

So, we once reached the top of evolution, but we said it in the ancient chaos. Social and cultural development is rapid and average life expectancy is growing rapidly. Perhaps this is the first time many women have survived in the times when they began to feel signs of aging in our evolutionary history. Initially, only a few people survived for 50 years, but it brought new challenges. If women maintain their birthrate indefinitely and people who have survived to the elderly continue to become pregnant, companies that are already hard to give birth are extremely dangerous. At least in the natural environment, there is the fact that the body of 50 years old is too old to give birth correctly.

If the possibility of life on Earth is small, it may be expected to take a long time. To be precise, you may have expected that life will emerge in time for subsequent evolution to smart creatures like ours that occurred before the cutoff provided by the sun's lifetime. This is about 10 billion years, after which the sun inflates the earth and swallows. A clever lifestyle that allows you to acquire space travel and escape to other planets. But beyond that, life on Earth will be destined to failure.

The purpose of biology is the product of evolution. Therefore, in order for life to have a biological purpose, it must be a product of evolution. But life is not a product of evolution. For evolution to happen, life must appear on the scene. Because evolution foretails life, life has no biological significance. Other purposes are useful. When we say that the purpose of the hammer is to strike a nail into the nail, we are talking about the purpose of their tool. This purpose comes from the intention of the creator of things. The purpose of the hammer is to hit a nail, for this is the idea of ​​the hammer creator when designing it.
