Answer:
Exponential growth can be described as the growth period in which the resources are enough and the population increases rapidly.
Population overshoot is the condition when a population becomes greater than the carrying capacity of an area.
Carrying capacity can be described as the maximum number of individuals of a population that an area can hold.
A phase of exponential growth is followed by a phase of population decline as the resources become limited and organisms start to die.
As the organisms starts to die, the population becomes stable again.
I would go with the last one, allowed scientists to better identify the location of fossils and change prior scientific knowledge
You test a hypothesis by carrying out an experiment.
Weaker, less evolved living organisms die in relation to survival skills, but the better ones stay.
For artificial selection, people select organisms based on what advantages they have to make them better.
Either the Porifera (sponges) or the Ctenophores (comb jellies). The jury is still out on which group branched off the main animal line first.
