Inter species breeding with fertile offspring

[gamila]

Many on here seem to think biologists know what species are
some argue that
species can interbreed with each other
yet this definition is shown to end in meaningless nonsense
take the Bactrian and dromardary camales

Wild camels have three more genes than domestic camels and so they have concluded that they are a completely different species.

yet these two different species can interbreed and have fertile off spring

this demonstrates colin leslie deans point that biologiy is not a science as its classifatory system ie species ends in meaningless nonsense

why don't you make a point other than: look what questions aren't completely understood!!!

in fact, i don't understand the points of your posts, most biologists know about the species problem from their sophomore year in college.

what you are trying to point out, i believe, is that their is a philosophical discrepancy to the definition of species. some believe that its an invented term and some believe that it is a natural term.... roughly.
the species definition is only blurred in some cases though, like different but related species (related cats, related dogs, related horses, etc) being able to interbreed despite being different species, and bacteria, which don't multiply sexually, but rather through binary fission and transduction and specialized transduction


so we all know about this stuff, lets move on to something productive

Perhaps taxonomically they are considered different species, but evolution-wise they have not completely speciated.

so colin leslie dean paradox is rendered to meaningless nonsense

Biology is not a science? So then Astrophysicists came up with vaccines and antibiotics. Or did we all just stumble upon those by accident.

[Jasper903]

Actually, that would be an example of technology. But biology is a science because the concepts that make it up are formed by the scientific method. You can't declare biology a non-science just because you don't like the major theories on specieation. Well you can, but you'll just look ridiculous

[papa1983]

Biological research led to those technologies.

But biology is a science because the concepts that make it up are formed by the scientific method

That there is no scientific method is shown by the early reception of darwins theory of evolution-this shows the fact that science has no method

some say the scientific method is falsification

but at the time of its presentation darwins theory was falsified by the cambrian explosion

even darwin saw the cambrian explosion falsified his theory

if falsification is the scientific method
darwins theory was shown to be false


colin leslie dean points out dawrin admitts the cambrian explosion destroyed his theory

"Nevertheless, the difficulty of assigning any good reason for the absence of vast piles of strata rich in fossils beneath the Cambrian system is very great. ...The case at present must remain inexplicable; and may be truly urged as a valid argument against the views here entertained." (Darwin, C., The Origin of Species, 1872, pp. 316-317.)

it has been shown in another thread

that Wilberforce showed that darwins theory was falsified
even darwin admiits the logic of Wiberforces points

Darwin himself thought Wilberforce's criticisms fair or at least faceable. `I have just read the "Quarterly" ' he wrote to Hooker in July, 1860. `It is uncommonly clever; it picks out with skill all the most conjectural parts, and brings forward well all the difficulties. It quizzes me quite splendidly by quoting the "Anti-Jacobin" against my Grandfather ... '33. A letter to Lyell on 11 August is significant:'... This morning I recommenced work and am at dogs; ... By the way, the Bishop makes a very telling case against me, by accumulating several instances where I speak doubtfully; but this is very unfair, as in such cases as this of the dog, the evidence is and must be very doubtful

this is a good example of the fact that science has no method
some say the scientific method is falsification
but even darwin saw the cambrian explosion falsified his theory

if falsification is the scientific method
darwins theory was shown to be false
thus
that should have been the end of darwins theory

[papa1983]

Woooow! What other of your posts are you going to recycle?

The Scientific Method
-Observation
-Create a hypothesis based on the observation
-Use said hypothesis to make predictions
-Test the predictions made by said hypothesis by experimentation or further observations.
-Based on results modify hypothesis. If hypothesis stands to tests and observations it may be promoted to a theory.

Of course tests and observations can prove a hypothesis or theory wrong so than you modify the hypothesis or theory.

fact is natural selection was falsified
