Pretty much. Or rather, all of biology leads back to Evolution.pastorkevin73 said:Please explain morphology and geographic dispersal.
Does evolution consider the entirety of biology?

Now, if you don't know the basics of biology and evolution, how can you speak against it?

You speak sooth, gluadys. Without evolution, biology would just be one big field of scattered, unrelated ideas. That's the strength of the theory. It is the glue that holds biology together. Creationism will have to do something similar if it is to move any further.gluadys said:Yes, evolution covers the entirety of biology, as nothing in biology makes sense except in the light of evolution.
gluadys said:Morphology refers to the structure of the body; how many bones, how they are linked to each other, placement of muscles and their attachments, nerve pathways, etc.
Geographic dispersal is the study of how a species dispersed from its point of origin. Before he became famous for his studies of human sexuality, Dr. Alfred Kinsey was an entomologist who specialized in a sort of wasp that makes galls in tree bark. One puzzle he solved was the original place of origin of the wasp. He knew that they seldom travelled more than a few feet from their place of birth, and by collecting and collating samples from all around the world he was able to trace them back to their point of origin.

I did some Googling for you, and here's what I found:pastorkevin73 said:How does evolution explain symbiotic life?
It seems plausible that what begins as a parasitic relationship might over the course of time evolve into a mutualistic one as the two organisms evolve to minimize the damage to the host.
But it doesn't always work like that. There are other examples where a mutualistic relationship seems to have evolved into a commensalistic or even parasitic one. Some parasitic fungi seem to have evolved from ancestors living in the mutualistic partnership of a lichen.
Some of the bacteria living in our large intestine supply us with vitamin K, thus evolving from commensalism to mutualism.
More Googling turned up this:pastorkevin73 said:How does evolution account for emotions and how did living creatures and humans evolve to have emotions?

Relevent quotes:
There's an example given in the first link:pastorkevin73 said:I read the above links. They don't seem to give an explaination for how creatures who are dependant upon another living thing in order to live (without symbiosys live being is unable to survive) were able to live before becoming dependant on another living thing.
In 1966, K. W. Jeon discovered a culture of amoebas that had become infected with bacteria (60,00 to 150,000 per cell). The infection slowed their rate of growth and made them much more fragile. But five years later, the amoebas still were infected but now no ill effects could be seen. Most interesting for our question, the amoebas — or at least their nuclei — had become dependent on the bacteria.
- When the nucleus was removed from an infected amoeba and replaced with one from a uninfected strain, the combination worked fine.
- But when the nucleus from an uninfected cell was replaced with one from an infected cell, the combination usually failed to survive.
From the same summary:pastorkevin73 said:Also there doesn't seem to be an explanation for how these creatures ended up being being dependant on symbiosys. What answers might there be for this?
If you have more questions, there are all kinds of references worth checking out at the end of some of those papers. Symbiotic relationships aren't my specialty.Evidently, after 5 years, the nuclei had become dependent on a bacterial function (an enzyme produced by the bacteria but no longer by the host). What started as parasitism had evolved into mutualism (the bacteria could not be grown outside their host).
In modern scientific context, this is known as abiogenesis. The idea of spontaneous generation is a little out-dated, and now usually refers to the (falsified) concept of life coming from decaying biomatter (i.e., that maggots come from rotting meat).chesslord243 said:evolution never said it got it right on the first try. what you're thinking of is spontaneous generation which is the explanation of how living organisms came into existence from non-living material.

Mutation and recombination worked on by natural selection. It's basic biology.pastorkevin73 said:Where does life get the information to evolve inorder to improve what is need in order to survive?

pastorkevin73 said:I think I understand what you are saying. It seems that this has to do what what needs to change. How does mutation and recombination get the information for how to change?
