Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
It is assumed that the amount of radioactive carbon left in the sample indicates how old it is. It is based on several assumptions, one of which is false.
Carbon dating is the ultimate benchmark of the evolutionary dating world.
Everyone assumes that dates that follow the word “radiocarbon” are accurate, precise and sure. The basic principle of radiocarbon dating is that plants and animals absorb trace amounts of radioactive carbon-14 from carbon dioxide (CO2) in the atmosphere while they are alive but stop doing so when they die.
Results from different techniques, often measured in rival labs, continually confirm each other.
Every few years, new geologic time scales are published, providing the latest dates for major time lines.
