AP Biology: Summer Summaries
AP Biology Summer Summaries
There are many differences between proximate and evolutionary causes and explanations on why we are such easy targets for diseases. The proximate explanations are described by its anatomy, physiology, and biochemistry. Evolutionary explanations go into detail on what would happen if we didn’t have the genes that cause us to get sick. Proximate causes look for what genes it is made up of and how it works. Evolutionary causes are why natural selection hasn’t eliminated the genes that cause us harm. For example the author uses the example of how with proximate causes our taste buds detects saltiness, sweetness, sourness, and bitterness then sends it to the brain to analyze it. But with evolutionary causes it detects saltiness, sweetness, sourness, and bitterness then sends it to the brain to help us cope with either our emotional or physical wants or needs. We would want to correct out defects because that would mean getting rid of our problems that prevent us from functioning properly. But even with these defects gone we wouldn’t our defenses to disappear because there are always new diseases around that our body hasn’t come across yet, so our defenses would allow us to face the most unpredictable environments without it being deadly but without our defenses we can get can get sick or even worse. The “outlaw” gene are genes that create their own way of spreading/growing at the expense of person or specie it inhabits. This in return shows the selection of genes acts only to benefit the genes and not the person or species. (Chapter 1)
Natural Selection will change a gene characteristic such as color or size if it will help the survival rate, it all depends on the current in environment that the gene is in. For example IF the tendencies to anxiety, heart failure, nearsightedness, gout, and cancer somehow increased reproductive success than those genes would be selected even if we suffer. Natural selection is also process which
