Please bear with me for a while and consider that evolution might be true. Can you think of a change that would make a human being more efficient in its environment? Can you think of a hundred? How about a thousand? How do you think all these changes could affect the way humans look like? Regardless of how dramatic the changes might be, would the species cease to be called Human to be called something else? What about one million changes ago? Why would the species be called something other than Human, because of how it looks at the time?
This makes no sense what are you really trying to say please make yourself clear and unambiguous? what are these changes that you speak of? And if this is the case why was there a break in these changes that occured why did they stop?
Don't you think you should, by your own initiative, research a bit to achieve a basic understanding of biological evolution theory, before you think about debating on the issue?
I really don't think it is necessary because the information that i recieve comes from those actually believe this to be true. I don't think my questions are unreasonable they may seem unreasonable because science doesn't have any answer for them.
No it is because the question is just plain stupid. e.g. you asked, "How can there be no first member of humans i would surely like to see a human and an ape breed and produce another human being.".
A human cannot naturally breed with an ape and even if with some genetic engineering we could solve the problem of hybridization when you have a mismatch of chromosomes (chimps have 48 we have 46) the resulting hybrid would not be a human (nor would it be a chimp) and it would probably be sterile (as with mules in which they too have a differing number of chromosomes of the two species: donkeys have 62 chromosomes, whereas horses have 64.)
Chromosome differences are not always that clear-cut - Przewalski's horse has 66 chromosomes, and as I'd mentioned above the domestic horse has 64 but of these two species breed then they produce fertile offspring, possessing 65 chromosomes.
Being sterile is an evolutionary dead-end. You don't get a new "species", you get nothing. So the two species, early-humans and early-apes, even if they did mate many ears ago if the results were sterile then that would be the evolutionary end. Once that happens then the two species go their own way forever.
What you are expecting is that by mating apes and humans you rewind 6 million years of evolution and end up with a human ? If this is what you've been told then the people telling you this are just plain liars if they purport to be teachers of some sort.
Come one - think for yourself.
Facts are that humans and apes had a common ancestor around 5 to 7 million years ago. Today humans and apes are seperate species both of which have evolved over those 5 or so million years according to the particular niche that the species resides in.
This may seem stupid to you but logical for me. I only know what i see. I see apes and I see humans but what I don't see is this other species which they are both ancestors from, again where is the evidence for this? Where is the evidence for this? And if they did exist what made them become sterile that they cannot procreate anymore? you don't have to explain what the end result of this cross breeding would be i already know. Please somebody answer my question. where is this evidence of this common ancestor?
Humans beget humans and apes beget apes if they are the same species why can't they beget the same offspring?
All of us, both you and I, see many people around the world but I do not see their ancestors. I don't see my great-great-grand parents, nor my great-great-great grandparents and so on down through time because they are dead.
Obviously we don't see the "common" ancestor too because it is dead.
Humans beget humans but no-one is saying that these are genetically identical. Our childen (and the offspring of apes) are subtly different. They are in fact genetically different but similar. These differences are naturally selected.
We know that we have ancestors but unless you are royalty or quite lucky, the recorded history fades in a few hundred years. Now consider the problem of identifying the common ancestor from before recorded history, from say before 30,000 years ago or 300,000 or even 3 million years.
That is what you are asking for.
What does happen though is that our genome records the broad flow of migrations. By comparing your genome with references you are able to work out where in the world your ancestors migrated though they do not show individuals.
The same applies to animals and plants.
DNA analysis allows you to show the broad relationships between populations as well as to show the precise relationships between near ancestors (you, your parents and grandparents): this is fact.
It also allows you to show the much broader relationships between species. This is highly regarded as being true and an extension of looking at near-relations.
So I cannot give you a common ancestor any more than you can give me your great-great-great grandparents but DNA analysis will show relationships between your family which would match your recorded history and this same technique can show relationships between species.
By denying the results of DNA analysis for species you also cast doubts on this same technique for near-ancestors. This is a bit illogical.
You said; "I only know what i see", but a few posts ago you said that "...I really don't think it is necessary because the information that i recieve comes from those actually believe this to be true.". Which is it ? You look for yourself OR you get others to look for you ?.
