True. It has been refined since then. But how do you mean?
Duration of what? Does Darwinian evolution put a constraint on it?
He does , slow but sure .

Why are the first humans without belly-buttons if primates gave birth to humans? You believe that?
Since noone gave birth to them. ☺
It makes no scientific sense.I believe this thread is about anti-evolution. May I not engage? I believe the first two humans were without belly-buttons. What is wrong with that?
You can believe whatever you like. But if you post your beliefs on a science discussion board, the validity of the science (or lack thereof) will be discussed. Hence the name.What's it to you if that's what I believe?
Not quite.The THEORY of evolution states the following: due to radiation affecting a creatures sexual organs, animals give birth to creatures differing significantly from their parents. This is concluded from Goeffrey St.Hilare's experiments. If the "deformity" is advantageous enough to allow the creature to survive to reproduce, then the genes dictating the deformity will be inherited by the offspring.
Yes. Some examples:How can something be a fact when ob-servation is neccessary for scientific methodology? Has anyone seen evolution in progress, given it happens so slowly (so it is stated.)
For the mutation to SPREAD it must be BETTER than the original.3)Yes as I wrote: the mutation must be advatagous enough for the being to reproduce. "Natural selection."
If you're going to participate, please try to observe convention and quote the pertinent passage that you are responding to.It doesn't matter as long as reproduction is viable, I.e. they can attract a mate.
Or just neutral, as most mutations are.For the mutation to SPREAD it must be BETTER than the original
How ladies choose their mates is driven by ... natural selection.Natural selection? Isn't it ladies' choice?
A recent discovery suggests that evolution of DNA can be traced back to archaea.If you're going to participate, please try to observe convention and quote the pertinent passage that you are responding to.
From the above response, one can't tell what "it" is and what it "doesn't matter" to.
Evolution is indisputable fact. It can be observed in any petri dish, any dog kennel or any fish breeding farm.
What is harder to demonstrate is the theory of natural selection.

Peek into microbes hints that packing scheme for genetic material goes way back
Single-celled microbes may have taught plants and animals how to pack their genetic baggage.
Archaea, a type of single-celled life-form similar to bacteria, keep their DNA wrapped around proteins much in the same way as more complex organisms, researchers report in the Aug. 11 Science. This finding provides new insight into the evolutionary origins of the DNA-packing process and the secret to archaea’s hardiness, which enables some to live in acid, boiling water or other extreme environments.
Behaviour[edit]
Lacking its own males, the LJJ biotype breeds with male Blue-Spotted or Jefferson Salamanders from March to April. The males' spermatophores only stimulate egg development; their genetic material does not contribute to the offspring's DNA. This mode of reproduction is called gynogenesis. The females lay cylindrical egg masses and attach them to underwater twigs. It is not often observed and its diet and lifestyle are unknown.

These salamanders live almost anywhere between south-central Michigan to adjacent Indiana and Ohio to western Massachusetts south to northern New Jersey. They are commonly found in or near shallow rivers and ponds in deciduous forest. There is an extremely limited population of the salamanders in Vermilion County, Illinois with only one remaining natural population known. They are considered endangered within the state. Theory states that the population may have dropped due to the vernal pool in which they live not retaining water for a long enough period for their tadpoles to reach metamorphosis
