While Studying...

I have one final exam left and it i biology. Just Bio 100 abut I am scared out of my mind. I have already explaind how this class and I wor together and it's not very good. Anyways. I am studying, going over old power points from class and the one that I am on now is about the Origin OF Species. On about the third slide my class discussed speciation and what has to be there for new species to occur and the next slide is about reproductive isolation (I feel like my blog needs sound effects to go with it. Right here there would be "DUN DUN DUN!!!!!") Please correct me if I understand this wrong, or don't because I won't be able to get the correction until after my final and that would be depressing to know I was wrong, but despite all the dating fanatics here in Provo, this is the home of reproductive isolation.

My slide lists barriers about why some species can't reproduce. This is Provo.

1. Temporal Isolation: Mating of flowering occurs at different times of day or seasons. I have a good many girl friends here in Provo, more than I am used to really, and it seems that they always like the boy that isn't looking to date right then or they know that one of their guy friends likes them , but the girl doesn't want to date right then. Lame! is what I have to say to that! Lame!

2. Habitat Isolation: Populations live in different habitats and do not meet. Just tonight I was talking to some of my girlfiends and two of them agreed that I should meet Benton! Oh and it would be wonderful! Oh and even if we didn't date we would be best friends! But, wait, he doesn't live in the Avenues across the street anymore. Well, dang. Enough said.

3. Behavioral Isolation: Little or no sexual attraction exitsts between populations. Well, dang.

At this point in the slide it says "Mating Attempt." Let's chage that to "Dating Attempt."

4. Mechanical Isolation: Structural differences in gentalia or flowers prevents copulation or pollen transfer. While this might be a little intense for the Provo first or second or third date, probably fourth as well although some crazies are married by the fourth date, the basic truth is still there. No compatibility on even a physical level. He likes sports, you like art. Or whatever. It's just not going to work. No compatibility.

5. Gametic Isolation: Female and male gametes fail to unite in feritlization. Sometimes, you really really do try to make it work....but it just doesn't. Everything seems like it should work. The compatibility is there, somehow you managed to overcome the other four isolations, but it still isn't quite there. Why? Who knows. It just didn't work out.

So basically, I ahve spent twenty minutes blogging, when I should have been studying, but, hey, when there is an idea, inspiration, biology won't stop a writer. Just don't ask what I made on my final. Or what my plans are for Friday. Those are just sad, sad questions.
