- crash course on evolution:
- August 26th, 2009
okay so i tried to have a conversation with a friend of mine, even though i sort of started making it into a debate....about evolution.
i first of all, think it's absurd to think that some creator made us.
and i secondly, think it's even more absurd to think that the earth is only millions of years old.
there is testiment that states otherwise for the above fact, that the earth is definately not as old as i would think it is, but most of the statements have questions in themselves.
i had decided to look at the facts and theories and came up with this:
1. a theory refers to a hypothesis that has passed so many tests that it is generally accepted as a true fact. therefore, the theory of evolution is true.
2. the volcanic ridge is a continuous submarine range of volcanic mountains that runs through all the ocean basins, so therefore our core is made of molten rock.
3. Our earth has had continental drifting. we have proven facts that the same animal fossils have been found on completely different continents.
4. There are two forms of sediment in the marine life:
A. Lithogenous - derived from the physical and chemical breakdown of rocks.
B. Biogenous - consists of the skeletons and shells of marine organisms. These can be called microfossils and have told us what organisms lived in the ocean in the past, they give us clues to ancient ocean temperatures, and so forth.
5. All living things grow, metabolize, regulate their internal environment, react to the external environment, and reproduce. The basic structural unit of life is the cell. The two major cell types are:
A. Prokaryotic cells - most ancient, simplest and smallest cells, bacteria mostly make up this type.
B. Eukaryotoic cells - organized and complex, contains DNA, a nucleus, and other things that our cells carry. this is us in the most simplest form.
So these eukaryotic cells and these prokaryotic cells actually make up a lot of the biogenous sediment in the ocean, which in turn [over a long period of time] can actually form into fossil fuels.
So that proves that we are part of the cycle. now onto the evolution part:
evolution occurs because individual organisms have genetic differences in their ability to find food, avoid being eaten, in metabolism, and countless other things. The most adapted ones produce more offspring on average. they also pass their favorable characteristics on to those offspring. the favorable traits become more common and over generations and population, it becomes more similar to the individuals. so they are continually adapting to their environments. this proves that evolution is happening.
so in short, our planet evolved, we die, and we recycle. end of story.
