This Concept Map, created with IHMC CmapTools, has information related to: 28 History of Life On Earth, 65 Million Years: Mass Extinction was One of Five Major Species Extinction Events since Cambrian, Great Diversity of More Complex Plants & Animals led to Fish & Proto- amphibians at 500My, Present Diversity of Life: both Microbial and Macrobial includes DNA Comparative Analyses, Great Diversity of More Complex Plants & Animals appeared ~550 Million Years Ago, Single-Celled Microorganisms: Prokaryotes lack Cell Nucleus, Simple, Multicellular Plants & Animals: Eukaryotes appeared ~1 Billion Years Ago, Simple, Multicellular Plants & Animals: Eukaryotes evolved to produce Great Diversity of More Complex Plants & Animals, History of Life on Earth is based on evidence from Present Diversity of Life: both Microbial and Macrobial, Mammals at 200My led to Homo Habilis 2 My, History of Life on Earth begins About 3.8 Billion Years Ago, History of Life on Earth is based on evidence from Fossils, Mammals at 200My led to Old World Monkeys at 25 My, Increasing Complexity began with Single-Celled Microorganisms: Prokaryotes, Reptiles at 300 My included Dinosaurs, Single-Celled Microorganisms: Prokaryotes were Only Lifeform, Dinosaurs until 65 Million Years: Mass Extinction, Single-Celled Microorganisms: Prokaryotes evolved to produce Simple, Multicellular Plants & Animals: Eukaryotes, First Fossil Evidence of Sexual Reproduction is found ~1 Billion Years Ago, Great Diversity of More Complex Plants & Animals led to Flowers at 130My, Only Lifeform until ~1 Billion Years Ago
