Hi- just wondering what science's answer is to this question. It is hard for me to imagine that simple random mutations are responsible for the formation of animal's organs.

Take for example the first animal that could see. I would think it would be highly improbable for random mutations to create the necessary faculties for sight. This animal obviously did not just suddenly have eyes, it would have been a more gradual change. How would random mutations alone slowly create the organs for sight? It would seem about as probable (or even less probable) than the sudden formation of single celled organisms from amino acids.

I'm not a creationist I'm just wondering about this issue. I know there are billions of years and many generations to create these things but statistically speaking it doesn't seem like it adds up.

Like one pill for a day. It contains ALL the carbohydrate, protein, fat, fiber, vitamins and the minerals. Only water is not in there.(drink the pill with water and drink more).

This thing might be useful for:

1) People who are on diet.(to restrict their food consumption )
2) Astronauts.(easy to store and eat)
3) People who are planning to go for a dangerous places.(hikers,snowy mountain hikers,crossing the desert,going into the mariana tench...etc)
4)parents who want their children to eat healthly without having to taste a single thing.
5)sick people...

Us humans are apart of the animal kingdom as well, and we are also mammals, so do we have any intincts or did we ever have them? This can include instincts that we can and cannot control.

Why do Christians always say Evolution didn't take place because their bible says it didn't? What about the other religions in the world? What about all of the evidence for Evolution? Why do they decide to throw blind faith into a book that is supposedly the word of "God", when there is no proof that god even exists?

I was on crunchyroll forum when I click on a link and it was a picture of a human body being cut up and dissect. How do the dissectors just cut up bodies like that and how can doctors operate on people? Just looking at the picture made me dizzy and nauseous

How does genetic engineering prevent genetic diversity? I understand that it DOES, but I don't understand HOW. Always the HOW question.

I am doing a science fair experiment involving bacteria growth. I have the incubator set to right around 100 degrees Farenheight. What, [if anything] will happen if it is incubated for more than 48 hours? Will it grow more or hamper it in someway?

I used to work at a science centre. I had had no previous experience in working with wild animals. I was nervous to start but very passionate about doing well.
Unfortunately, one morning when I was misting some of the habitats and cleaning the water dishes, a small amount of bleach water had been left on the counter where I had placed one of the bowls. The following morning, one of the tree frogs had died. I understand that the gravity of one, tiny tree frog dying may not seem very bad to most of you, but where my job was concerned, I probably appeared to be unprofessional, maybe even "immature". The fact of the matter is that I took it upon myself to complete the morning tasks before everyone arrived and simply made a mistake. I was then transferred elsewhere to finish my credit.
I'm now looking to volunteer at an animal refuge centre where she also works. How should I approach this situation? What if she recognizes me and makes me look bad to everyone else? What if she mentions it?
