Document Summary
1: describe the basic sequence of the evolution of life from its initial development, define evolution, including both micro- and macro, differentiate natural selection from other forms of selection, develop scenarios illustrating natural selection. What are the key events after the initial origin of life: eukaryotic cell development, various energetic pathways, multi-cellularity, colonization of land. Multicellular evolved several times in eukaryotes: the first multicellular organisms 1. 5 1. 2 bya, plants primitive marine algae, animals soft-bodied marine invertebrates, 570 million year old fossil embryos (figure 26. 15) Movement on to land evolved independently several times. What process was involved in the development of organisms after the initial origin of life: evolution, process that occurs once you have life on the planet. Evolution any change across generations in the genetic makeup of biological populations: generation, the only information that can be passed through generations is genetic makeup.
