How We Got On Land, Bone by Bone

Travel back far enough in your genealogy, and you will run into a fish.

Before about 370 million years ago, our ancestors were scaly creatures that lived in the sea, swimming with fins and using gills to get oxygen from the water. And then, over the course of millions of years, they began moving ashore, adapting to the terrestrial realm. They became tetrapods, a lineage that would eventually produce today’s amphibians, reptiles, birds, and mammals. As scientists have unearthed fossils from those early days, one lesson has come through ever more loud and clear: the transition was not a single leap. Instead, it was drawn out and piecemeal.

More fascinating is the absence of data on the breeding and origination of domesticated dogs. The variety in size, features etc., makes it impossible to believe that all were descended from the grey wolf.

Specialty dog breeding by our primitive human ancestors defies logic.

So my question is - when and where did all the dog species begin - and when did their wild ancestors become extinct?

i.e. Take a look at this vapid article: http://www.dog-harness-solutions.com/types-of-dogs.html

You seem upset.

The thrust of evolutionists if I understand their thought process as that ond species evolved from an amoeba, later into a lungfish type creature, then eventually evolving into snd becoming Man

In very broad strokes, that is correct (though this doesn't do justice to the mechanisms - mutation, natural selection, genetic drift, epigenetic influences, etc.) by which this occurs.

But it is essential to bear in mind that the evolutionary process is extremely slow - so slow as to be virtually undetectable on a generational level. Thus, at no time is it expected or necessary (in the case of sexually reproducing creatures) for an individual to mate with another individual whose genome exhibits a marked difference.

I commend you on your open-mindedness, and would encourage you to consult someone in your circle of friends and acquaintances with a background in Biology who can better explain this to you.

As scientists have unearthed fossils from those early days, one lesson has come through ever more loud and clear . . . .

. . . . yeah, it's loud and clear that the Tiktaalik is doing for the
Darwinists at Na't Ge'c what the Coelacanth wouldn't (couldn't) do.

So mammals came from fish/reptiles that left the sea?

Explain dolphins and whales.

Did some mammals return to the water (not polar bears or otters or even seals that live in both environments)?

Or did mammals come into existence multiple times?

You both might like to read this book: http://www.amazon.com/The-Science-God-Convergence-Scientific/dp/1439129584

It makes some interesting and well supported claims. I enjoyed the read and reread it as it was packed dense with information.

Here’s a video if you don’t like to read:

I ate my ancestors with tartar sauce at Long John Silvers the other night.

Lol!! You cannibal, you....

Things aren’t always what they seem. ;-)

Yes, Dolphins and whales descend from mammals that returned to the sea. In Darwin’s time no transitional fossils of that particular sequence had been found, but he predicted that transitionals between land mammals and modern cetaceans would be found and he turned out to be absolutely correct; a very nice sequence of such transitionals exist. No-one can say for sure that any particular “transitional” fossil is truly an ancestor of modern cetaceans but if Darwin was wrong his prediction was extraordinarily lucky (along with many other “lucky” predictions he made about the natural world and the fossil record.
