[quote=Aren]@aznseal: I've always had real confusion on this: is the evolutionary tree based on similarities across different organisms of chromosomal DNA or mitochondrial DNA? because I feel like there would be no transition between prokaryotes to eukaryotes if it was the former...[/quote]

There are many different views on phylogeny that scientists still disagree with so I can't say =/

[quote=Snovvy]@aznseal:
-While humans are definitely intelligent, there is possibility that some species are more intelligent than us. Certain qualities are leading some experts to conclude that many marine mammals, most notably some species of dolphins, whales, and especially orcas, may be more intelligent that humans. Smarter gorillas are about as intelligent as slower humans. With information like this, I have deducted that the only reason we are the rulers of this planet is because we just so happened to get the right mutations to give us the bodies we have, such as bipedalism, the ability to pass on knowledge to future generations, and most notably, our hands/thumbs/etc.

-There should be no reason the brain of a creature couldn't have evolved with silicon as opposed to carbon, which greatly increases the likeliness for life to occur on other planets.

-Polygamy would be good for society as it promotes the passing on of good genes over bad genes.

Thoughts on these things?[/quote]

What criteria are you using to measure intelligence? Because by any definition of the word I can think of, humans dominate.

The smartest captive apes (chimpanzees, bonobos, orangutans, etc) operate on the level of a 3 year old human child, maybe 4 year old if the ape is really really smart.

[quote=catdograt]How do we tell if a specific genetic trait is beneficial to be passed on? For instance, sickle cell anemia may be considered detrimental, but in areas in Africa, the people tend to have sickle cell anemia, which is resistant to malaria. Is there any definitive way to tell which traits are beneficial? o.o[/quote]

It all depends on the habitat. Also, some genotypes are passed down but are expressed in the form of different phenotype depending on environmental stimuli. Generally, if a specific gene trait helps the organism survive, it will more likely to be passed on.

@Snovvy: I would also argue that our ability of expanded speech is also a tool. Yes some animals are intelligent, but I feel that intelligence only gets so far. The smartest gorilla is still killed by a gun, and it's our ability to use our intelligence to the highest degree that makes us dominant.

Polygamy is good for gene transfer for sure, but you have to factor in quantity over quality. No racism intended, but some low income minority households tend to have more kids because they hope that eventually, one will hit the jackpot and get lucky and be amazing at sports/school. More wealthy families tend to have fewer kids in order to groom the few to as high of a degree as possible. With that said, I don't think nature's law of polygamy would apply the same way to humans.

@ToxicEffect: Their branchial arches develop differently, they have different scale types, different proportion of dermal and endochondral bones, and of course the material of their skeleton. Teleosts are generally more derived than chondrichthyes

@aznseal:

For the most part funding for PhDs runs out after 4 years, hence why most people finish it in around that time-frame.

They essentially do the things as many doctors in practice, but in terms of prestige, it's lower than a MD.

LOL. It was funny when his hair was long and he sounded like a girl, but now it's not funny at all. So just don't. Thanks. When I first heard Baby on the radio I [b][/b]thought it was a girl[b][/b] and I couldn't stop laughing with my friends cuz he was like 16 yet he sounded like a 7 year old girl.

I want to either be a surgeon or go on and teach/biomedical research.

I'm paying for medical school out of pocket.

@xreminiscing: I want to go to med school so I started looking around for a major I liked as a back up. I ended up taking evolution as one of my upper level science courses and I loved it so now i'm going into evolutionary/developmental biology. I really like learning about physiology and development and how that relates to evolution so it's pretty much anatomy class after anatomy class xD I'm also not too familiar on psychology. The most i've learned about it was in bioethics where we argued the rightness/wrongness of it.

1. How did you get into evolutionary biology? Evolution is byfar my favorite part of biology, but I could never see myself doing an entire major on it.

2. What are your feelings toward the field of evolutionary psychology?
