Animal X lives in a forest with very tall trees. While he can survive the best fruit grows at the top of the tree. Over time his descendants have long necks well evolve long necks. I can accept its not chance the long necked ones survive and take over short necked. But the fact the neck grew in the first place has to be chance unless the animal genome is intelligent and can past down the next one has to have a longer neck.

according to science's own laws, spontaneous generation is impossible (see Louis Pasteur), so my question is, if life HAS to come from pre-existing life, and all cells HAVE to come from pre-existing cells (one of the three rules in the cell theory), where did the first life and the first cells come from? it makes no sense to me how life just seemed to pop up out of nowhere. that's why i believe that religion has a small bit of truth to it. but for the love of all things human please DO NOT give me an answer that basically says "god said let there be life and 'poof' there was life." i am not a religious person, i am actually very scientific, which is why i am asking SCIENTIFIC people for a SCIENTIFIC answer.

Choose three of the following bioethical issues. Explain both sides of the issue (views of those in favor of the practice and those opposed to the practice) and then give your viewpoint and explain why you hold that view. In your explanation, use Scripture to support your viewpoint.
1. In vitro fertilization
2. Stem cell research
3. Cloning
4. Assisted suicide
5. Euthanasia

P.S: It's up to you if you want to do more or less than three.
Thanks guys in advance for your answers.

My Christian friend has stumped me. Please don't talk about "micro-evolution" stuff please.

Does that mean they also dismiss the cell theory, the theory of gravity, the theory of plate tectonics, the theory of electricity?

Cells.......speculation?
Gravity......a scientific conspiracy?
Observable annual continental drift..........crap?
Electricity......bunk?


HONESTLY, how deep in denial do you have to be?

In April 2004, scientists at Tokyo University of Agriculture used parthenogenesis successfully to create a fatherless mouse.
In theory, artificial human parthenogenesis could be used to reproduce humans, but this is highly unlikely due to ethical concerns. Use of an electrical or chemical stimulus can produce the beginning of the process of parthenogenesis in the asexual development of viable offspring.On August 2, 2007, after much independent investigation, it was revealed that discredited South Korean scientist, Hwang Woo-Suk, produced the first human embryos through parthenogenesis.The offspring of parthenogenesis will be all female if two like chromosomes determine the female gender (such as the XY sex-determination system), but male if two like chromosomes determine the male gender (such as the ZW sex-determination system), because the process involves the inheritance and subsequent duplication of only a single sex chromosome.”

There has been a lot of research and an equally large amount of money spent on teaching animals ( especially apes) a form of language. Research some of the work done attempting to teach animals to communicate. Write about summarizing the research. What gains and loses have occurred and have we taught animals to communicate with us and to what extent?

I tried this question on some learned friends with this result: seems logical; if mitochondrial DNA comes from the mother to daughter its ok for the y to come from the dad; can't be the same y due to diversity; what's a chromosome; asking why (Y) is a man thing. Here is a problem. Mitochrondia ALSO enter the egg as part of the sperm cell .No real problem, unless you are hung-up on mother to daughter transfer of M-DNA. Because which ever human sperm fertilized the first human egg the M-DNA was forever mixed.Yes, to the female offspring but ALSO to a male kid. Each of which continued to pass on M-DNA to a fertilized egg/zygote. It should be noted that " M" of the M-DNA is not "maternal" but "M"itochondrial.And IT didn't come from a MOTHER somewhere in Africa umpteen years ago. You could just as well trace the paternal mutation rate in subsequent generations since the sperm number of M-DNA is tiny compared to the egg .What say ye? Please a reference, if you know of any.
