When Charles Darwin voyaged on the Beagle, he saw variations of finches on various of the Galapagos Islands. Basically, the only variation was the size of the beak. What he observed was a fact. Over time, different conditions can make variations in different groups of animals.
This fact is what allows the American Kennel Club to name new breeds (variations) of dogs. Variations of dogs develop when different genes in a population are isolated from other gene pools. The isolated gene pools start to take on a “family” resemblance to each other, same as families of people look similar.
Eventually, with enough inbreeding, a new breed of dog that looks different from every other breed of dog, will develop. But, guess what – the end product is still a dog. Nothing evolved into anything else.
But, when this happens in the wild, due to various circumstances, it is called evolution, and the resulting variations are given new species names.
That is all Charles Darwin saw — isolated populations of finches that lived on different islands.
Then, because he wanted to explain away God as creator, he concluded that since these birds looked different, that all life on earth is related to each other and changed gradually from one to the other.
That took a big stretch of the imagination. But, the only other alternative is God, the Creator. Some people will go a long way to avoid believing something they do not want to believe.
There are many types of variations in all types of animals. These minor variations are given “species” names. Now, the definition of species is that they can only interbreed with others in the same group.
But, people who give new names to new species do not bother to find out if it is indeed a NEW species, in a genetic population unique to itself.
Dogs, wolves and coyotes (God’s dog-kind) can interbreed, grizzly bears and polar bears (God’s bear-kind) can interbreed, lions and tigers (God’s cat-kind) can interbreed. This is a very short list of animals that can interbreed.
All of this interbreeding gives evidence that God created the basic kinds of animals, and then the variations developed as the animals moved throughout the world, getting in isolated populations by choice or by geography.
Evolution is a faith without any proof.
In the beginning God created the heavens and the earth.
