The Heavens and the Earth. • In the beginning, stellar dust, elemental particles, and space debris gathered into a mass. • Around ___________________ and enough meteor bombardments, the Earth heated and melted causing the elements to ____________________________. • The rearrangement provided a beautiful _____________________________________ ____________________________________. The light and darkness. • The atmosphere would originally have been made up of _____________________________________ _____________________________________ ____________________. • Once an atmosphere formed the sky would show ____________________________________. The water and the dry land. • About _________________ the Earth cooled enough for the rock to _________________________ • About _____________________ the Earth cooled further and __________________________________. • The water covered most of the land creating a primitive “_____________________”. Plants and fruits and seed bearers. • How does the world go from “organic soup” meaning all the elements needed for an organic molecule: carbon, hydrogen, oxygen, nitrogen, phosphorous, etc. to complex organic molecules? Miller and Urey Life in a Bottle • Recreated conditions of early Earth (atmosphere, sunlight, heat, and soup). • Struck the system with energy (simulated lightening) and then let the system set. • ___________________ ___________________ ___________________ ___________________. From Amino Acid to DNA drivenreproducing bacterial life. • Once organic molecules were available in the Oceanic Soup, they could ________________________________ ________________________________. • We can create these in lab conditions and they are “___________________”. As nucleic acids condense: • As the nucleic acids created in the lightening storms bonded, __________________________________. • In modern cells, some short RNA and DNA sequences can _________________ (i.e. they don’t need enzymes or each other to copy themselves.) • Perhaps, _________________ was the start of modern reproducing life. Let the waters teem with life. • Once the single celled organisms evolved, life teemed with these microscopic creatures-as evidenced by _________________________. • As _________________ began to occur in these small creatures they slowly poisoned themselves with highly reactive and toxic (to them) _____________________. The breath of life. • As ________________________ reactions occurred all over the planet. • The ocean turned from _________ to the clear blue we have today as the water ______________ and the rust sank to the bottom of the ocean. • The sky shifted from a __________________________________. • Many of the little oxygen producers could not protect themselves from the highly reactive and poisonous oxygen, dying out and leaving only fossils on the Earth. Let us make man. • About _________________, prokaryotic cells started evolving again, gaining ____________________ and becoming very primitive __________________. • __________________________! • These cells engulfed small photosynthetic cells and viola! The ____________. • These cells engulfed small aerobic bacteria and viola! The ____________________. A companion. • As ______________________ developed in Eukaryotes, the possibility and potential for adaptation increased dramatically and sped up the natural course of evolution. • And so, a process that began 4.5 billion years ago, required 3 billion years for multi-cellular life to begin now speeds toward ever increasing and complex life forms.
