Macro-evolution joshua_robins https://padlet.com/joshua_robins/jgu18e61crk7/wish/176299599 Micro-evolution is used to refer to the changes in a gene pool of a population over time which results in small changes to the organisms in the population but these changes do not result in the newer organism being classified as a different species. Macro-evolution is the opposite as it is used to refer changes in organisms which are significant enough to be considered a new species over time, with this in mind the new organisms would be unable to mate with their ancestor, assuming we were able to bring them together.

Natural Selection- Organisms that are better adapted tend to survive better and transmit these traits to further generations and continue thriving unlike others without these qualities.
Mutation- Mutation occurs when a DNA gene becomes damaged or changed in such a way as to alter it's genetic message carried by that gene. A mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed. 
Migration/gene flow- Transfer of genetic variation from one population to another.
Divergent, Parallel and Convergent Evolution-evolution are all different types of evolution that describe how species become different or similar.
Sexual Selection-when you select a partner for their characteristics. Time is well...... Time. The changes don't happen instantaneously. Organisms change over time.
Genetic Drift-variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.
Homologous Structures-An organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
Vestigial Organs-An organ that has lost its main function through evolution.
Ontogeny Recapitulates Phylogeny-when certain animals have similar embryos.
Molecular Evolution-change in the sequence of cellular molecules, E.G DNA, RNA, Proteins.
