The evolution theory is a theory evident in seven branches of biology: species distribution, comparative anatomy, taxonomy, embryology, cell biology, and paleontology. Species distribution was apparent after the separation of Pangaea when organisms of the same type would fulfill separate niches in the separate continents they had been relocated in. The different niches all required different organs and traits, thus causing their shapes and sizes to change according to the use or disuse of the characteristic they previously had. (Asimov 138+) Comparative anatomy is the study of evolutionary relationships based on common traits and structural differences. Taxonomy is an artificial system which shows species relationships in formally ranked order. Cell biology, the fourth branch relevant to the evolution theory, shows multiple similarities between organisms. Embryology has shown evolutionists that two remarkably organisms dissimilar as adults maybe remarkably similar as embryos, which could be a method of bridging gaps between species.

Keep in mind that simply because something has been given defining characteristics or has had a book written on the subject does not make it exist. Owen Gingerich, a Historian-Astronomer at Harvard University once said, "Genesis is not a book of science. It is accidental if some things agree in detail," (Asimov 138).
Genesis is implausible because it states that on the third day God created grass, herb, and fruit trees, but it was not until the fourth day that he created light. On the fifth day, God created swimming animals and flying animals. On the sixth day God created land dwellers, including humans. (Oxford 1+) Should this have been true, it would have placed humans living on earth at the exact same time as dinosaurs, and other animals that we know we were not in co-existence with due to the fossil record. The fossil record actually tells us that the first signs of even vaguely human life were more than four and a half billion years after the Earth's birth (Asimov 138+). Based on this information, scientists believe Genesis to be fictitious. However, creation scientists argue that at the time God created the world, a day could be equivalent to what are now thousands or millions of years. This, too, is impossible because it is common knowledge that a plant cannot reproduce without pollination, or survive without sunlight to use for photosynthesis.
A more convincing timeline is evident in the evolution theory. The origin of life, as according to evolution was in the Precambrian era, three billion years ago. Algae and fungi-like plants were the first to arise from the Earth's soil. Six hundred million years ago, in the Cambrian era, the extensive fossil record began. It consisted mostly of trilobites and brachiopods, which accounted for eighty to ninety percent of all fossils from the era. This is why the Cambrian era has come to be called the "Age of Invertebrates." (Hotton 130+)
The first primitive land plants were birthed in the Silurian era, 425 million years ago. Then, in the Permian era, which was 280 million years ago, vertebrates made their advance, and reptilian species dominated the land. For another 95 million years, reptiles were still most abundant, until the dawn of the Tertiary era, when mammals replace the reptiles as most plentiful species. Then, finally, in the Quaternary era, the Australopithecus, an early form of man, made his appearance. Climatic fluctuations changed the form of the Earth...
