how do planarians reproduce (other than regeneration)?

and...i have a question to fill out that i can't find the answer to:

"Since the planarian are animals and do not make their own food, give one reason why they might possibly need an eye spot."

thanks.

I don’t think that DNA was first, I think that proteins were first and then DNA appears. It is like our history we were first and then we create our knowledge, I like to think that we human are like proteins and the DNA is like our knowledge. It’s an amazing idea, I like to think that in a future we are going to organize in a big cell, like those first proteins…….

Does electricity flow from point to point, from a positive charge to a negative charge? And what exactly is a charge?

Not cloning but entirely a new species

Have we actually found fossils that are transitions from an ape to a human??
I dont understand how you can believe that a human, can come from an ape because our DNA is sooo similar, 1% difference right? well we're obviously different than apes, so that 1% difference is a HUGE difference because i dont have fur all over my body, and i dont act like an ape.
another thing is where did these apes come from? I dont understand how this could be a random occurance. Our bodies are so complicated we still dont understand all of it.
I'm not trying to offend anyone, i just want to know more because right now i dont buy it.

From the publication of "On the Origin of Species" in 1859 until the Scopes Trial in 1925. I would like to know what scientists and others thought about evolution after Darwin's publication. How long did it take until scientists other than Wallace accepted it?

I have a two questions about evolution. Please understand that I am trying to understand the theory of evolution--not disprove it (Believe me, I know I don't have the knowledge to even begin to attempt that). I hope I can even explain my questions right.

First, have we ever seen a new species occur in nature? If so, what was/is it?

Second, if a species is defined as a group of animals that can reproduce fertile offspring, who does the first one of a new species reproduce with so that the species can continue? There must be some cutoff point where one female gives birth to offspring that is a different species. If that is the case, it would not be able to reproduce with any of it's predecessors. Or could it?

Do you believe in animal research? can you give me some reasons? Do you think it is acceptable for scientists to perform research on animals like fruit flies, rats, mice, and rabbits?

Would it be possible to isolate and use the beneficial genes from this organism to engineer plants (food) that take on the beneficial traits of being heat/vaccuum/radioactive/cold resistance for possible use to grow in otherwise unhospitable environments? Thanks.
