Re: Re: "Your contention ..."
but not all cats are lions.
within the cat family there is quite a variety of natural and human produced types.
Within the canid family also, wolves, coyotes, the wild dogs throughout the world -- all are distinct within the family.
But humans have developed such a variety as to demonstrate how evolution is possible -- within such a minute difference of DNA lies such an infinite variety. This should demonstrate how easy it is for living things to evolve.

Re: Test tube babies and cloning
Both of these still start with all-human components!
By the way, have you heard that a test tube baby occupies a prenatal "womb with a view!?"
Thanks for your comment, Soul!

Unless test tubes count! And cloning!

Your comment brought a chuckle or two. I could just see you conducting this little experiment!
Thanks, so much, Ariala, for sharing this!

Interesting study...I tried a similar experiment when I was a kid...I put
all sorts of things in a test tube...dirt, orange juice, cheese and you name it. I left it outside and then one day I went out there and there was an ugly hairy bug in it. I thought for sure I had created it LOL

Re: Humans
Spinner, I am here talking about a man and woman co-habiting with each other in the traditional sexual manner to give birth to another human being. This is being done every day. I am not talking here about "clones," or anything like that, although I know that there are experiments going on there as well!
Thanks for your comment.

Re: "Your contention ..."
Xeno-x, your statement that "your contention that biological types cannot change (I perceive that is so) is in error." NO! Let's not make assumptions! Your above assumption is in error. I fully realize that there is much variety within a given species. However, dogs cannot produce cats (only other types of dogs or wolves), and cats cannot produce dogs, only other types of cats. Beware of "imaginary numbers!" (My last post.) Each type of cat belongs to the "family of cats," and each type of dog belongs to the "family of dogs."

this have been used a lot -- but the only thing the experiment demonstrated
was that the myth that the flies sprung from basically nothing was just that -- a myth.
people's perceptions were then broadened.
just as Galileo broadened perception.
your contention that biological types cannot change (I perceive that is so) is in error.
Brussels sprouts.
Broccoli
Cauliflower
this from Wikipedia: "domesticated cabbage was eventually bred into widely varying forms, including broccoli, cauliflower, cabbage, kale, kohlrabi, and brussels sprouts, all of which remain the same species."
And yet they are so different. A small step to be sure, but these all developed into different types within the species, with different characteristics, so that you would not recognize one to be related to any of the others; and broccoli gives rise to broccoli and cauliflower to cauliflower, each a separate and distinct organism within the species.
This has used to demonstrate evolution.
Species can change. Take the dog, for instance. If you have a dog that is a particular breed, that distinct breed in all probability did not exist 200 years ago. Many of the breeds of dogs and cats were developed within the last several centuries. Look at the variety. And their genetic makeup is identical. The DNA of a chihuahua is identical to a St. Bernard and their predecessor, the wolf. And yet they are so different.
Changes can be subtle. Within the short span of a lifetime, they can go unnoticed. And yet, as they develop over so many years or eons, they make something different than all that has gone before.
You observe a narrow patch of time and conclude that what you see is real.
Observing over the eons gives us a different conclusion.

It is written that man will ultimatly destroy himself I believe that man will make man if it has not already been done, I believe from mans own willingness to create man and play God he will create the anti christ. I might be crazy!
