The evolution theory is still a debated topic. It is not fact. So, until there's a solid scientific proof, I won't believe it. Personally, I think that animals and humans will change and adapt to its environment but not to the extent of the animals to become another new species.

Peace.. biggrin.gif

you need to look at the world of microbes. so many strains of microbes evolve so fast that they are resistant to new generation antibiotics.

anyway, what's your definition of "become another new species"?

not this again, a scientific theory is supported by scientific fact, so evolution is a theory and also an fact. scientific theory does not become scientific law and vice versa, creationist arguement that because evolution is not proven as it is not yet an law only show they dont understand the scientific term.

buddy, have you been living in a cave or hibernating in an underground chamber for decades? Evolution is a FACT, the evidence supporting it is overwhelming, it's time to take off the blindfold and seek for the evidence, they are there waiting for you to discover...

Most of the time people protests against evolution are in hit and run posts. They state their disbelief, make a few claims that evolution is a speculative theory, give the example of the monkey and his cousin or something similar and that's the end of discussion as soon as it started. Amazing that they could have learnt anything from this short stint. It seems as if after a series of responses here and elsewhere, telling them how ignorant they are, they have nothing else to offer but yet refuse to abandon their unsupportable position. After a few months, they return with the same drivel, same silly assertion yet to disappear soon after.

a bird will not become a mammal, though they both shared a common ancestor , i.e reptiles...

a bird change to a cat will falsify the theory of evolution. You are ignorant of the theory but yet you dismiss it without much of a thought, based only on hearsay.

evolution does not mean cat can change to bird or bird can change to cat, it said bird and cat share an common ancestor as all the species on the tree of live can be trace to a common ancestor. all the fossil and DNA evidence so far have supported this theory, there is no solid reason to doubt that is false, like there is no solid reason to doubt the theory of gravity will still be true tomorrow, there is possiblity that gravity will be goon tomorrow, science dont deal with absolute certainty, but the possibility is so low that it is not reasonable to believe that it will happen.

so is evolution, all the evidence discover so far have supported the theory, and there is a lots of evidence, first there is all those fossil and then there is the DNA, we can now accurately draw the tree of life the way Darwin can never imagined. it is not reasonable to reject evolution because the remote possibility that there is suddenly be a bunch of evidence disproving evolution been discover tomorrow.

evolution can also be seen in embryonic development. ever wonder why human embryo has a "tail" that slowly disappear?

Have you read the idea of "phylogeny recapitulates ontogeny". Although it is wrong but there are strong connections between ontogeny and phylogeny particularly at the early stages of embryonic development. Have you read the book "inner fish"?

sorry,if you're trying to challenge evolution with a video that tell tales without even provide verifiable evidence to substantiate your god's existence,then you can bet your last dollar you can still see evolution being taught tomorrow.

But that is the best they can do. If you expect something better that, you will be disappointed. smile.gif

Personally, I think the most useful direction in which we could evolve would be to be more resistant to pollutants and toxins.

then it's time to pickup your book and study.

Scientists believe that all living being in this planet are come from the same ancestor. Which you might called it an alien micro-organism from outer space that fall into planet Earth.

Panspermia is only a hypothesis.

It can be demonstrated that all living beings came from some ancient simple organism 3 billions years ago, whether they are the same ancestor or not, I am not sure.

hypothesis are mean to open for ppl to find new evidence to disprove it.

until then, it mean it receive no challenge.

hypothesis mean no one need to pay much attention to it until it have evidence to support it and being verified by several other scientist, then it will become accepted.
