<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.  In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.  This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.  After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.  If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.  When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>

How homologous structures and vestigial structures are evidence of evolutionary relationships.
natali 33 [55]

Answer:

Due to presence of these structures in ancient as well as modern organisms.

Explanation:

Homologous and vestigial structures are the evidences that show  evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.
