Re: Why are flowers "beautiful"?

http://www.youtube.com/watch?v=TzN-uIVkfjg&feature=related at 2:00 Dan gives a reasonable accounting for "why". I wish you would have set down here what the professor said about our subject instead of giving us the URL. As an atheist who thinks evolution, I just could not go through a...

Hey, all you guys are retards. Obviously the one true god is the Flying Spaghetti Monster. He just covered up the evidence to make it look like evolution is real and the universe is 13.7 billion years old.

Re:

Ok brace yourselves. The largest flower in the world is Raffesia arnoldii. It looks and smells like rotting meat. How does that work for Julie5's Freudian theories? I suppose it just goes to show that variety is the spice of life. And size isn't everything. You see, there is a God.... The "rot...

Certain genes may be modified epigenetically by mechanisms such as methylation, by only a specific parent.

Re: Meiosis produce haploid cells, twice. How?

no no no no no no A diploid cell is in interphase and doubles it's DNA to make chromosomes with two chromatids(sister chromatids). When it enters meiosis 1 the homologous chromosomes get separated and each chromosome of the homologous pair goes to a new cell. So in meiosis 1 you get two haploid cel...

Re: 2 Basic Questions

For the moment, I have only two questions: 1: What amount of evolution has not been observed? 2: What amount of evolution has been observed? 1. not observed - nearly 100% 2. observed - next to nothing Cat's response lacks scientific evidence. 1. Many experiments have been conducted that support tha...

I'm guessing bacteriophage T4, since that is used most commonly, especially in biotechnology.

a) Because the frequency of recombination is zero (all offspring resemble the parental types), the genes must be completely linked. b) It is called pleiotropy. White flower and short corolla can produce only 1 gamete type since it is homozygous at both loci, and red flower and medium corolla can pro...

Re: on phylogeny / what are we ?

That being said, I don't think that the transitional species between our most recent common ancestor and modern humans are considered apes, because by the definition of a paraphyletic group, "A group of taxa is said to be paraphyletic if the group consists of all the descendants of a hypotheti...

Re: on phylogeny / what are we ?

But you seem to switch from accepting a term and rejecting it, back to accepting it... depending on what you are trying to prove. You said Yes, I believe this ancestor would still be classified as an Old World Monkey (an ape). but you also said... No, because apes is not a clade (monophyletic group...

As I said before, the whole question is about terminology and definitions, not about concepts. That being said, what we are arguing about does not have to do with whether or not humans evolved from apes, it only has to do with the officially accepted definition of a couple of biological terms. Accor...
