Eras of Life on Earth
During the eras of earth, various animals were created, eradicated, and new beings emerged. These are described by order of appearance in the historical geology (paleontology). Scientists believe that through the emergence of DDT powder and disinfectants, new insects come to creation with novel characteristics. In medical researches, scientists claim that they have discovered new insects or other beings that they have not seen before. If we compare today’s beings with beings of many millenniums ago, we are sure to see differences.
