Demotivational - Creationists

Human VS Gorilla skeleton. Why does the idea of a common ancestor sounds so absurd to them?

" Why do they all still have fur, regardless of climate, and we don`t?"

Actually.... we do still have fur! And not just in certain places.
In the womb we go through an earlier primate stage where we are covered in fur like hair, a throw back to our early ancestors, much like our fish stage of development :)

"Why would we evolve to be inferior and vulnerable"

This is your opinion.... we are not scientifically "inferior". And we are only vulnerable in different ways to other creatures.

"to have a need for clothing and heat sources?"

Well, we mostly didn`t need these when we were evolving so I think you are missing the point. We evolved to be (mostly) hairless in a very pleasant Africa. Once we moved out of the forests evolving furless frames may have helped us stay cool. There is also some thought (although not very popular) that part of human evolution happened in semi aquatic environments. There fur can be useless, so selection could favor less hirsute individuals (interestingly this could also explain our webbing between digits...but as I said, this is not a popular theory).

Evolution of Human Body louse (which live in clothed humans not naked humans) also suggests that we lived without clothes for about 1 million years without hair. Africa treated us just fine for that.

Fur and hair is by no means a crucial trait. Elephants and Rhinos found it profitable to lose it, as did the ancestors of whales and dolphins when they took to the sea.

" But before our brains reached that point, why would we begin to take on a less efficient posture"

Again, you are trying to make your opinion into science... the two do not mesh.

Our posture is quite helpful from an evolutionary standpoint. Standing allows us to see further (especially in the Savannah where we evolved)giving us the ability to spot prey or predators. It kept our hands free for gathering food, eventually using tools, and escaping back into trees.
Bipedalism also may have helped our brains evolve in the long run. So, just because you don`t understand something does not make it a negative.

Science on homosexuality and evolution is still in its infancy, but there are a number of interesting studies and theories on why it exists...and they fit in nicely with evolution.
For example the best studies tend to show that homosexuality may be a reaction to the mothers system against her babies. It tends to affect later children in families with many siblings more often, and if this is shown to be true could actually be evidence for some sort of natural population control.
Gay people don`t compete for mates, and thus can benefit the population by hunting and gathering, without potentially lethal competition in mating season.
Homosexual contact in the animal world seems to be a sort of stress relief valve (yes that sounds dirtier than I intended)so it may have started as only an act, and evolved into full on homosexuality in the long run.
But again, this is all very new science.

Any other questions?

Edit:

Rowdy, excellent link. It illustrates perfectly what you are saying, and shows how our evolution is tailor made for africa. Great stuff.

Our ancestors were by no means weak, frail ect. They were and are some of the deadliest hunters the animal kingdom has ever known. Having great stamina, intensity, intelligence and a dogged determination early homosapiens would literally run down prey to exhaustion then swoop in for the kill. Frail? weak? No, I think not. On thing for sure, nature only favors the strong and our species has the monopoly.
For the type of evolutionary niche our ancestors filled, having fur would be a liability

Some humans still practice this ancient method of hunting check out this vid

@huntsman_420:
"Why do mammals from impala in Africa to polar bears in Canada, kangaroos in Australia, deer, elk, monkeys, gorillas..."
-Because the continents are moving and used to be all together. Also, kangaroos are not mammals. They`re marsupials.

"Why do they all still have fur, regardless of climate, and we don`t?"
We do have remainings of fur but our need for fur decreased. Fur requires resources to grow. If the fur is not required it will be evolved out because it is a waste of resource for the body. Other mammals did the same. For example, some species of moles are furless and on top of that they`ve also become almost completely blind because there is no need for eyesight for these animal`s lifestyle.

"Why would we evolve to be inferior and vulnerable, to have a need for clothing and heat sources?"
The ancestors of humans originated from Africa. We became physically inferior to some other species because the invention and use of increasingly developed tools removed the need for sheer strength. Strong bodies require more food to develop so it evolves out if not required.

"Not to mention physically weaker, clumsier... I know someones going to say "our brains are superior, so we can make clothes, etc..." But before our brains reached that point, why would we begin to take on a less efficient posture, and loose our ability to handle harsh climates?"

Hands were more useful than paws for the survival of the species. The upright posture was more appropriate for the lifestyle the species adopted, being able to carry and use tools better. As I said, the ancestors of humans originated from Africa so there was no need to be able to survive cold climates. As the humans started to colonize colder locations, they invented clothing to protect themselves.

He never said they were. Read it carefully. He was listing mammals, polar bears, kangaroos, deer, elk, monkeys, and gorillas all as separate animals.

^ Right, but it was a moot point anyway.

If you analyze the sentence carefully you`ll see that the animals he cited were examples of "mammals". His sentence could be broken down to "why do mammals like (list of examples) all still have fur?".

Anyway, as leighCedar said, it`s a moot point anyway.

A moot point it may be.

Regardless, marsupials are mammals. http://en.wikipedia.org/wiki/Marsupial
