If evolution is true, which came first, the brain or the heart. they both need each other for survival, so which came first. and if living things come from living things, where did the first living things come from. like the cell theory states, new cells are produced from old cells. so, where did the first living thing come from if living things come from living things, and never from unliving things. answer me that

1. Why do living things CARE if they have offspring ? I mean life is a series of chemical reactions right ? But why would a conglomeration of chemicals go through all this trouble to procreate? I mean stars and planets don't. Rocks don't seek to preserve rockdom and water does not attempt to ensure there will always be wetness so why do organisms seek to recreate themselves ?
2. Why the variety ? Evolution doesn't cut it. When the first life forms became sussessful why didn't it stop there? I mean there are types of algea that have been around for over a BILLION years. Long before complex organims. So why did complex organisms develop ? What purpose could that possibly serve the original ones from which they are descended?
3. Since human beings are just intelligent animals everything we do is natural right ? Why should we care about other creatures beyond the extent to which it is to our benefit?

If you remember me again, I have another question about genetics.
I think that a cross of the two homozygous long-whiskered seals's offspring will have no short-whiskers (which is 0%) because in a punnet square it would look like this:

W W
W WW WW

W WW WW

Then I think the cross between the two heterzygous seals punnet square would look like this. I dont know what the percentge is.
Please correct me if ANYTHING is wrong.

W w
W WW Ww
w Ww ww

This is the question.
Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes for long whiskers & the recessive allele (w) codes for short whiskers. What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one that is homozygous dominant and one that is heterozygous? Explain your answer and use a punnett square.

I need to perform my science fair experiment over winter break. So I cleared it with my teacher and brought home the equippment. I made 60 Petri dishes of agar and they are in my refridgerator. They're not setting up though. This might be because I cooked the agar in the microwave with the water, instead of boiling the water and then dissolving the agar in it. It's been 24 hours now, and they're not really setting up. Any advice?
