* Evolution often results from... 1. Reproductive errors during DNA synthesis if these are maintained in a population it will lead to evolution. 2. Allowing a population to survive in changing environments 3. Something that helps with this process of evolution is adaptation. 4. Adaptation ~ is something that allows these organisms to be more fit in a given environment. 5. Natural selection ~ Natural works if there is a trait that is selected for that will increase the probability of survival of those individuals in the populations. (The traits that are being selected are really the adaptation) 6. Charles Darwin and Alford Wallace ~ they came out with the theory of evolution by natural selection. Species ~ A group that naturally reproduce in the wild. you can create fancy creatures like tigers and lions turning them into ligers.

But that doesn't happen in the wild. You have your lions and your tigers. Separate species. Plants are the perfect thing to look at evolution, modifications. Evolution of life ~ Life came from things that were not living. The beginning of life was chemical evolution . This happened about 4 BYA . (billion years ago) During chemical evolution their were chemicals they interacted to produce molecules, and these molecules could act as a template to produce more similar molecules. The earliest molecules they think resemble either DNA or RNA (they have no idea which they know that they can reproduce) You think of DNA and RNA. 3.8 bya these molecules were inclosed in compartments and these compartments were the early cells ( FIrst cells ) PROKARYOTIC CELLS ~ These early cells were unicellular and they do NOT have any organelles. The next big thing in evolution some of these prokaryotes acquire the ability to do photosynthesis.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
