I'd suggest starting here: http://en.wikipedia.org/wiki/Evolution

That is a horrible explaination of evolution!!!

I tell all to read this before starting the discussion since most have no clue what they are talking about, they only know what some idiot told them about evolution...

Can a unicellular organisms replicate multicellular life? Because I am arguing with Burz and rs199 who actually think this is flipping possible after all the links I have supplied (that they obviously haven't read)...

From Single Cells to Multicellular Organisms18

Introduction

Go to:Top▲
Single-cell organisms, such as bacteria and protozoa, have been so successful in adapting to a variety of different environments that they comprise more than half of the total biomass on earth. Unlike animals, many of these unicellular organisms can synthesize all of the substances they need from a few simple nutrients, and some of them divide more than once every hour. What, then, was the selective advantage that led to the evolution of multicellular organisms?

A short answer is that by collaboration and by division of labor it becomes possible to exploit resources that no single cell could utilize so well. This principle, applying at first to simple associations of cells, has been taken to an extreme in the multicellular organisms we see today. Multicellularity enables a plant, for example, to become physically large; to have roots in the ground, where one set of cells can take up water and nutrients; and to have leaves in the air, where another set of cells can efficiently capture radiant energy from the sun. Specialized cells in the stem of the plant form channels for transporting water and nutrients between the roots and the leaves. Yet another set of specialized cells forms a layer of epidermis to prevent water loss and to provide a protected internal environment (see Panel 1-2, pp. 28-29). The plant as a whole does not compete directly with unicellular organisms for its ecological niche; it has found a radically different way to survive and propagate.


Panel 1-2>

The cell types and tissues from which higher plants are constructed.
As different animals and plants appeared, they changed the environment in which further evolution occurred. Survival in a jungle calls for different talents than survival in the open sea. Innovations in movement, sensory detection, communication, social organization - all enabled eucaryotic organisms to compete, propagate, and survive in ever more complex ways.

Single Cells Can Associate to Form Colonies

Go to:Top▲
It seems likely that an early step in the evolution of multicellular organisms was the association of unicellular organisms to form colonies. The simplest way of achieving this is for daughter cells to remain together after each cell division. Even some procaryotic cells show such social behavior in a primitive form. Myxobacteria, for example, live in the soil and feed on insoluble organic molecules that they break down by secreting degradative enzymes. They stay together in loose colonies in which the digestive enzymes secreted by individual cells are pooled, thus increasing the efficiency of feeding (the "wolf-pack" effect). These cells indeed represent a peak of social sophistication among procaryotes, for when food supplies are exhausted, the cells aggregate tightly together and form a multicellular fruiting body (Figure 1-31), within which the bacteria differentiate into spores that can survive even in extremely hostile conditions. When conditions are more favorable, the spores in a fruiting body germinate to produce a new swarm of bacteria.

I'm surprised you're not aware of this, since it's basic biology, and you've repeatedly claimed to have a better grasp of biology than major researchers around the world both government and private, every other type of scientist, professors, and everyone else ITT.

Since you know what you're talking about, why don't you explain the theory of Evolution to us, in your own words?

The Faith in this one is strong - yes!!!

The only 'evidence' you provide is asking why doesn't a rabbit have Human Chromsomse 2.....Get lost.

Correct

There is no specie named an 'Ape'. Ape is generic term hominids. So I'm not quite sure what you are getting at here.

That wasn't directed at you, I added it in because DBS seems to think that if modern apes don't "evolve" into h. sapiens over 3-4 generations, the theory is invalid.

THANK YOU!!!!

I know I already posted that… but, thank you! I appreciate you sending links that support my argument! It’s appreciated!! I would give you a Rep, but I doubt you know that you just helped me!

The evidence I provided you was in ALL life that common life share a common ancestor, but have a different number of chromosomes, the model for your Chromo 2 doesn't match.

Why does it only match for humans and not the rest of all life on the planet that also has a different number of chromo's than it's close relatives?

Why is that Grasping?

You simply cannot grasp that only future generations will receive mutations, not past generations.

Your ignorance doesn't change facts.
