How old do you think earth is? Earth is 4.5 billion years old lol, more than enough time.
For an ape to become a man theoretically he must mutate only 1 % of DNA. At first you might not think this is very significant, remember the mutations have to be exactly the order of human person. It is estimated that for 1% difference only one million mutations are needed. How can one have a million mutations with each mutation in the direct order to make a human.
Example of only 5 mutations George Simpson , an evolutionist estimated to get five mutations in the exact order it would take 10,000,000,000,000,000,000,000 chances Simpson concludes,
".... unless there is an unknown factor tremendously increasing the chance of simultaneous mutations, such a process has played no part whatever in evolution."
and more over it estimated that to form life with 20 amino acids it would take 1 X 10 40,000 chances. Impossible to comprehend.
What chance did evolution have ?
And here is the catch evolution is considered as a continuous process. So why don't we have any transitional species (the popular ones like the intermediates between ape and man) in the society today?
As evolution is a continuous process, then the evolution from ape to man should continue and that mean every era these creatures should be present, rather we see well defined genomes present.
The theory of Evolution cant answer the claim of the existence of "self". What is self, it is not defined by our body or the chemicals, to answer this Richard Dawkins replied "We don't know it " in his God Delusion. Simple as that
And i did mention the odds to form a DNA the primordial era of the earth was brazen with excessive high temperatures that would not have facilitated life. Therefore the total 4.5 billion years want used for the development of the genomes.
Imagine you have a monkey in a room for twenty-four hours, typing a way on your laptop. In the morning you enter the room and you see, “O Romeo, O Romeo, where art thou O Romeo? Deny thy father and deny thy name…” The monkey has miraculously written out a Shakespearean sonnet!
now what are the logical explanations to it?
1) some one else did it
2) chance
I wouldn't magnify on some one else did it. I mean what s there to discuss. A guy/ gal came it and just did it.
Lets take the second option . A research was done to justify the claim and it was found that for a monkey to randomly type and produce:TO BE OR NOT TO BE; an independent pattern of English grammar and Shakespearean play it will take it 28 billion years. How old is this universe (forget earth) a bit more than 14 billion years.. Now to form DNA and RNA (some microbes depends on RNA rather than DNA , but they use Lygase and other enzymes but those are mumbo jumbos not needed here

) which has an independent pattern of life and self replicating units and the intricate design how long do you think it will take?
This problem in the theory of evolution appertains many(many renowned scientists) to believe life was started by alien lifeforms. But that poses another question who created the aliens .
Now coming to Transitional species again
most of the Fossils shows stasis and sudden appearance rather than transition like
Chambered Nautilus "It remains essentially the same as its ancestors of 180 million years ago.... a living link with the past." National Geographic, January 1976
The praying mantis fossilized in amber is dated 40 million years.
The coelacanth was thought to become extinct 70 million years ago was found alive in the 1930's off the coast Madagascar.
Now another thing that i stated, why don't we have a 747 stranded when a tornado sweeps over a aircraft junk yard. why don't we have the Arabian and Sahara dessert covered with silicon diodes due to the lightnings and sandstorms . the chances for those are higher than the chances to form the 20 necessary amino acids and the DNA strand and RNA. The probability of assembling the genome is between 4-180 to 4-110,000 and 4-360 to 4-110,000.
And more over the Newly emerging picture of life from genetic studies do not fit with the traditional "tree of life". There are unexpected dissimilarities between very close groups. like the difference between rats and humans genome is very less rats/mice have around what 91 % similarities (i got the news i myself am surprised.i ll check it more) what similarities do we exhibit?
and there are further long discussions by Jonathen Wells(forgot the name of his books

"my defense hey i am studying mech engineering not these

)
