Answer:
For about 4.5 million years, and still exist on earth
Explanation:
Humans are the most highly complex organisms and are comprised of well-developed brains. It shows advanced characteristics and is well developed social animals that can adapt well in any environment.
The humans are one of the major God's creation which has played and still playing a great role on earth.

Answer:
film sensitive to radiation that is removed and developed to measure exposure.
a device used for monitoring individual cumulative exposure to ionizing radiation.
Explanation:
Film badges are monitoring devices that contain photographic film which measures and record the wearer’s exposure to different ionizing radiation such as X-rays, gamma rays and beta particles. The photographic film within film badges is very sensitive, functions as a detector, and is enclosed in a vapor and light resistance cover which disallows chemical vapors, light or moisture to have an effect on the film. Film badges give a lasting radiation record and it can also differentiate between different energies of photons.
There’s proteins (muscle) lipid (fat) calcium )bones) and carbohydrates (mostly for energy)
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
