What were Darwin’s two main points of Evolution and what did the two points mean?
Natural Selection • Some living thing are more suitable or better for survival • Descent with Modification • An organism slowly accumulates mutation over million of years • 1.2.
Gradualism • the slow accumulation of mutation over time • Punctuated equilibrium • When organisms stay stable for long periods of time. • Then, there is a short amount of time while there is a major change when organisms mutate • Then, they stay in that phase for a long timeonce again.
Who observed the amount of time that affected mountains, rivers, landforms and masses?
Who observed that people produce many children, but we don’t use all our natural resources?
Who wrote up his findings and sent them to Darwin only to find they both had very similar observations?
What is the chronological “story” showing the life of animals, plants, humans?
Natural Selection VS. Artificial Selection
Natural selection • Where the organisms survive or don’t survive based on survival of the fittest • Artificial Selection • Where it permits organisms to live even though they would not have if left up to nature and visa versa
Antibiotic overuse will cause things such as medications to not work in the future because organisms adapt to them called natural variation • Pesticides work in a similar way, farmers use them on crops
Geographic Isolation • Where the location is difficult to breed • Reproductive Isolation • Where two individual are not on the same reproductive cycle such as skunks • Behavioral Isolation • Where a physical action that either separates or keeps the females from being interested in the males such as the cranes’ dance
Divergent Evolution • 2 or more organism that started out together on a similar path but later on they go into different paths • Convergent Evolution • Organisms start at different point but they come together with similar features million of years later. • Parallel Evolution • 2 or more organisms evolve along a specific pathway but don’t share a common ancestor
What will I get from doing something vs. What will happen to me if I get caught
What is it called when there is a change in the gene pool from generation to generation?
Stabilizing Selection • Get rid of extremes and chooses the average • Directional Selection • An extreme favors over other extreme • Disruptive Selection • Favors both extremes at the same time
What gas did not exist in the world until the first organism on Earth did what?
Oxygen did not exist in the world until the anaerobic (did not breath oxygen) gave off the oxygen as by-products. Therefore, oxygen became a part of the atmosphere after million of years
Nature hates an area void of life such as a vacuum. Therefore, if there is the possibility of life, there will be life.
