ALTER2EGO -to- EVERYONE: DEFINITION OF MICRO-EVOLUTION: "Evolutionary change below the species level; change in the genetic makeup of a population from generation to generation." (SOURCE: Biology, 7th ed. Neil A. Campbell & Jane B. Reece) DEFINITION OF MACRO-EVOLUTION: "Evolutionary changes that happen over very long periods of time. This usually refers to the development of large new branches of life, such as vertebrates or mammals." (SOURCE: Evolution: The History of Life on Earth, Russ Hodge) DEFINITION OF SPECIES: Loosely speaking, a species is a related group of organisms that share a more or less distinctive form and are capable of interbreeding. As defined by Ernst Mayr, species are: "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups." Species - Definition | WordIQ.com ORGANIC/BIOLOGICAL EVOLUTION is the theory that the first living organism developed from nonliving matter. Then, as it reproduced, it is said to have changed into different kinds of living things, producing ultimately all the different forms of life that have ever existed on earth, including humans. And all of this is believed to have been accomplished without intelligent direction or supernatural intervention. (Sources: (1) LIFE--How Did It Get Here? By Evolution or by Creation? pages 10-11; (2) Encyclopedia Britannica, page 1018) DARWIN'S THEORY IN 1859: "Therefore I should infer from analogy that probably all the organic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed." (Origin of Species, p. 484) EVOLUTION THEORY IN 2012: "The commonly accepted scientific theory about how life has changed since it originated has three major aspects. "1. The common descent of all organisms from (more or less) a single ancestor. "2. The origin of novel traits in a lineage "3. The mechanisms that cause some traits to persist while others perish" Evolution - Discussion and Encyclopedia Article. Who is Evolution? What is Evolution? Where is Evolution? Definition of Evolution. Meaning of Evolution. DISCUSSION QUESTIONS: 1. Just like Charles Darwin, the modern-day evolution scientific community asserts that every single animal that has ever existed came from one common ancestor aka came from a single animal (macro-evolution). Is there evidence proving that humans or animals evolved from completely different beings than what they presently are? 2. Fossils are the bones of long-dead animals. Do fossils exist that show evolutionary transition of one type of animal to an entirely different type of animal (eg. a whale evolving into a bear)--which is an example of macro-evolution? 3. When people in the pro-evolution scientific community speak about animals evolving into "new species," are they referring to one family of animal evolving into an entirely different family of animal (eg. a squirrel evolving into a bat or a dinosaur evolving into a bird)--which are examples of macro-evolution? Or are they referring to variations of the exact same type of animal (eg. Doberman dog, Bull dog, Rottweiler dog)--which is an example of micro-evolution?
