Re: How much math do you need to know in order to do biology?

It depends on the field of biology. If you want to study bugs and things, you could get by with no math. I'd avoid fields such as population genetics. Most of molecular biology is quite biochemical and so requires doing a lot of simple calculations, but it's more arithmetic than mathematics. So ther...

Re: Methods of plant identification

I can't help with the programming, but for ideas on how to design your key(s), you can look at the many online or print keys available.

It's a caterpillar, probably of a moth. No idea what species.

That's the best you can come up with after a week? I think I'll let the readers of this thread judge for themselves our relative levels of denial and scientific expertise. I only jumped into this thread briefly to clarify your position for others, which I think I have accomplished. Best of luck in s...

Re: Genes in the same linkage group are inherited together?

A centimorgan is the distance between two loci where the frequency of a crossover between the two loci per generation is 0.01. So the frequency of crossover between two genes 1.5 cM apart will be 0.015, and the frequency of a crossover between genes 140 cM apart will be 1.4. The alleles of the all g...

Re: Genes in the same linkage group are inherited together?

To be a bit more accurate, it's the alleles of the genes that are of concern here. The order of the genes themselves will remain the same barring genetic events such as deletions, insertions, translocations, or inversions. You can get more information by searching for "linkage disequilibrium&qu...

Re: Re:

Please, read my post carefully. Nice try, Cat. I had asked for an example of archaeological evidence of "new gene events". You provided a link to an article that you claimed provided evidence of "a "new gene" gained". Please read your own posts more carefully. I hope y...

Re: Re:

http://www.isogg.org/tree/Keller%202012%20Oetzi%20Iceman.pdf It's an example of archaeological evidence. When some gene found in today's human genome in not found in the genome of ancestor (mummy), it is said to be a "new gene" gained = indirect evidence. I quickly scanned through the art...

I know what deduction is. I was hoping to get an example of archaeological evidence you claim deduces "new gene events".

Re: Is evolution as simple as we think?

Not exactly. Thank you for your reply, but my question required a yes or no answer. By replying with "not exactly", I still do not know what your point is. What would be direct, reproducible evidence for the spontaneous appearance of a new gene with a novel function in a genome? And how c...

Re: Is evolution as simple as we think?

I'm going to jump in here to get something clear. Cat, are you claiming that there is absolutely NO evidence for the spontaneous appearance of ANY new gene with a NOVEL function in ANY genome?
