Explain what the term “evolution” means. What does the theory of evolution state ? As a hypothetical example, Darwin used North American black bears, which were known to catch insects by swimming in the water with their mouths open:\"I can see no difficulty in a race of bears being rendered, by natural selection, more aquatic in their structure and habits, with larg… In science, a “theory” is understood to be a concept that has been extensively tested and supported over time.

Resistance of bacteria to antibiotics, insects to pesticides, and weeds to, A human disease that showed promise of eradication in, the1960s - but before we could eradicate, resistant strains survived. Common ancestry does not mean the, species we find today have evolved from each other—dogs did not evolve from cats, and humans did not. This preview shows page 5 - 7 out of 10 pages.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
