Im having a debate with a fundamentalist about those glow in the dark pigs I saw posted earlier on on this forum: http://news.bbc.co.uk/2/hi/asia-pacific/4605202.stm
I posted this under the heading, "Should humans dabble with evolution"
The fundamentalist reply was:
"This is not evolution"
My reply to him:
Am I correct or is the fundamentalist correct? Do humans effect evolution and if so, in what ways?

It's not evolution.
In biology, evolution is the change in a population's inherited characteristics, or traits, from generation to generation.
The glow in the dark pigs are going to have piglets which are surprise surprise, going to inherit the genetic changes of their parents.
A simple test to see if this is evolution. Did the pigs evolve? Yes, they now glow, they have evolved. Whether is man influenced or not, the new pigs have a different genetic makeup from normal pigs... hence, they have evolved. The theory of this evolution is that they had jellyfish dna inserted into their DNA..
The specifics in case of forumite nit picking:
Evolution consits of the following main mechanics:
- Selection and adaptation (Darwin)
- Recombination
- Genetic drift
- Gene flow and population structure
- Speciation and extinction
I highlighted Speciation because thats the bit I am going to use an example:
Artificial speciation
New species have been created by domesticated animal husbandry, but the initial dates and methods of the initiation of such species are not clear. For example, domestic sheep were created by hybridisation,[4] and no longer produce viable offspring with Ovis orientalis, one species from which they are descended.[5] Domestic cattle on the other hand, can be considered the same species as several varieties of wild ox, gaur, yak, etc., as they willingly and readily reproduce, producing fertile offspring, with several related "other" species.

As you can see, man influenced speciation is a great example of man fiddling with evolution which has been done in this case.
It is evolution prom
