Study Of Flower Color Shows Evolution In Action - More proof for Evolution!, page 1

1) Organisms DO NOT change from one species to another. They do not shapeshift and - BAM! Rabbits have become humans! Like magic!

...

You have got EVOLUTION WRONG, if you think that we came from plants, or that we came from dogs.

WRONG.

The theory of evolution states that living things transition from one form to another WITHIN their own genus and family, but this transition occurs due to environmental pressures to force the changes.

In other words, NOT EVERYTHING on EARTH came from the SAME type of organism! Multiple bacteria and primitive organisms must have existed EONS ago, not just ONE.

Don't know much about horss and cows, but humans and orang utans have IMMENSE scientific/behavioral similarities there must be a midpoint transition somewhere that indicated we EVOLVED from them, through ADAPTATION and NATURAL SELECTION, after being induced by environmental pressures, which refer to things like food shortages.

Let's use the example of the giraffe, the most common piece of evidence, which many scientists believe came from zebras, or another type of EXTINCT striped equestrian animal (I forgot its name, but it looks like a red zebra with a lot of redundant fur).

Four processes:

1 - Environmental pressure - Plants get taller, resulting in animals unable to reach their food, because most of the shrubs are being picked off by the shorter animals.

2 - Adaptation - These animals have to stretch out farther to eat at the taller trees which the smaller animals cannot touch.

3 - Generic Mutation - Little baby equestrian animals come out with deformed necks and slightly elongated upper bodies.

4 - Natural Selection - The babies which do not have such mutations DIE because they cannot reach the tall trees, so the ones which DID mutate survive and pass on their genetics through more offspring, and over THOUSANDS of YEARS this becomes the GIRAFFE WE SEE NOW.

Understand?

it's not saying a giraffe BECAME a human. Or a dog became a human.

2) Monkeys --> Humans. IS WRONG.

Nope. Monkeys --> Transitional creatures --> Homo erectus --> Homo sapien

Same thing with the giraffe-zebra-equestrian EVIDENCE, but it's with humans this time.

I've used this example before, in previous threads.

Orang utan found no need to hang around from trees using their feet. Why? The pressure that their favorite fruit is now being grown on LOWER branches of trees, or they can be easily accessed without going through all that Tarzan crud.

So, they learn to walk (lope, really, if you've seen orang-utans). And generic mutation occurs, and natural selection, and over time the feet flatten out and stop being curved.

Homo erectus/Transitional primate has been derived.

Homo erectus / Transitional primate found that STRAIGHTENING up, and being able to swing arms wildly helps to WARD OFF PREDATORS and ENEMIES. Same thing happens.
No more hunched-over, though now you can still see evidences of that occurring in old people or people who have "regressed" mentally. Being curled keeps us SAFE, which is the FLIGHT part of the Fight-flight response.

The climate got hotter - as we all know, it IS STILL getting hotter. The end of the Ice Age, so homo erectus didn't need that thick coat of fur anymore. Same thing happens. Fur disappears, becoming hair. Though some men I've seen - you could mistake their hair for full-grown fur.

This is how it works, folks. Above all, IT MAKES SENSE.

3) Creationists believe in so much more far-fetched things.

God created the Universe in SEVEN DAYS? Do you know how big the Universe is? Heck, does GOD, should he exist, know how big his own universe is BY NOW? (The universe has always been expanding, by the way)

God created Sin? Who even knew what the word "sin" was, before homo sapiens came along? Homo erectus had sex and got into fights for the sakes of survival and to increase reproduction chance.

God created Man and all the other animals? Without Man, there wouldn't even BE the notion of God.

Without Man, if we weren't LUCKY enough to have had all the circumstances go right for us, all the animals would still be living free, unhunted, undomesticated, wild and uninhibited. Man comes along and buildings come along. The idea of ONE SINGULAR POWER RULING OVER ALL comes along. Cooking food with forest fires comes along. Fashion comes along. Everything comes as a result of MAN, not as a result of GOD.

Man evolved.

Creationists don't believe in some thing that actually MAKES SENSE logically through evaluative process.

What does that say?

4) This flower showing changes in color provides evidence for primitive evolution. It does not FULLY prove it, but it provides some evidence.

It in fact proves solely the processes of GENERIC MUTATION and NATURAL SELECTION, but NOT ADAPTATION. In order for the process to be evolution, adaptation is needed.

There are some environmental pressures - hummingbirds choosing only a certain kind of flower, perhaps due to pollution, etc.

Natural Selection 1 - All the flowers that did NOT get pollinated will die off.

Generic Mutation - All the flowers that did get pollinated will carry with them the genes coding for that same color, leading to a mutation across the entire species, at least within that region, whereby all the flowers have that color due to mass pollination, over the course of time.

Natural Selection 2 - All the flowers that did not receive the mutation will die.

Though, clearly, NS 2 doesn't fully occur because this is a REGIONAL observation, and also because the environmental pressures are shifting constantly, causing flowers to die off and new mutations to appear, back and forth.

Everyone's good?
