There have yet to be ANY fossil records of the missing link between reptile and bird.
Think about it... A bird would have to have feathers or stretched skin, hollow bones, and larger lungs/stronger and different designed shoulder muscles to be able to fly. By natural selection, any partial deformity that would bring a creature to that state, without even one of these traits, would be eaten by the closest predator.
What about Linux.... i mean, what about the penguins... it is a bird but it don't fly... well, it fly in water but not in the air !!!
Or the Moa ( extint due to men ) who was a wingless bird...
Ostrich are other bird who don't fly...
On the other hand, bat are good flying mammal... Fish like hatchetfishes of the Amazon can fly... The Ommastrephidae are flying squid... a max of 50 meter jet propelled fly !!!!
Point is that you take for a fact that flying and bird are related... the few example show that not all bird fly and that not only bird can fly !!!
If we look at all the cancers, defects and shorter lifespans of humans now, we can see how the DNA replication of Humans is loosing more information as time marches on. If we plot this DNA deterioration on a graph, we can deduce that humanity isn't as old as Evolutionists try to claim.... humanity is only 6,000 years old, according to DNA deterioration. This much DNA deterioration would cause humans to be extinct long ago, if humanity is millions of years old.
Shorter lifespans !!! Well, some number...
- Neolithic : 20 yo
- Bronze Age and Iron Age : 26 yo
- Classical Greece and classical Rome : 28 yo
- Medieval Islamic Caliphate : 35 yo
- 1200-1300 A.D.: 43 yo
- 1300-1400 A.D.: 24 yo (due to the impact of the Black Death)
- 1400-1500 A.D.: 48 yo
- 1500-1550 A.D.: 50 yo
- Current world average : 67.2 yo
As for cancer, it is somehow funny... a cancer cell is a cell who don't die... yes, they are immortal... they duplicate but have mutated in a way that mechanism for kill the cell don't work anymore...
About humanity being 6000 years old...
In 6400 BC ( 8412 yo )the Halaf culture was created in Lebanon, Israel and Palestine, Syria, Anatolia, and Northern Mesopotamia ... before this, in 9000 BC ( 11012 yo ), the first city ( 2000-3000 people ) called Jericho was created... The oldest settement, 10700 BC ( 12712 yo ) was found near Aleppo, including two temple...
If humanity is only 6000 year old, it mean that it is alien who have build these settlement, these city or these first big culture... or maybe it was ape like in the film "planet of the ape" ???
If you wish to write some BS, best to make some research first... if you have say that humanity was only 15000 year old, it will have be better because there was not real civilization in these time... well, 15000 is not good enough because of some painting ( http://en.wikipedia.org/wiki/Lascaux
) who are +-17k yo...
