As a gardener and conservation ecologist myself I know that Darwinian evolution is bunk. However there is adaptation within species to make groups more able to survive in different environments. The analogy in this article is more in tune with this idea than with the faulty theory of evolution of new species. As Crimson Dragoon mentioned, tabletop games and video games did "produce viable offspring" which could reproduce.
I liken the relationship between tabletop games and video games to the one that exists between Icelandic ponies and Arabian horses. Icelandic ponies have short stubby legs and a low center of gravity that make them extremely sure-footed on rocky terrain and a shaggy coat of thick, long hair to insulate them from the cold. Arabian horses are long legged and are better able to run on soft sand. They have short hair and slick, thin skinned coats to help them cope with the heat. They look and behave fairly differently and live a world apart from each other, but they are still horses. If you really wanted to, you could breed an Icelandic pony to an Arabian horse and get viable offspring.
Tabletop games are strategy and storytelling simulations that are adapted for being run by people without the aid of machines. In their "purest" form, they can be played with nothing more than the imaginations and communication skills of a group of humans. The dice, minis, maps, books etc. are all aids that help reduce confusion and arguements and help diverse people to imagine something somewhat close to the same thing (though in your own imagination, you can still envision something different looking from what you see on the table, but at least you have a common frame of reference when discussing what you think is happening with the other people).
Video games, in their earliest days, were still mostly about being aids to the imagination as the graphics and sound were so primitive that you had to imagine what the blob of pixels on the screen was supposed to be. Just try playing almost any Atari 2600 game without trying to imagine what those blocky things are supposed to be and you'll see what I mean. Without the human imagination, those games are little more than dull puzzles. With the advent of more and more fancy graphics and more realistic sound, video games are gradually squeezing out the need for imagination on the part of the player. Play most Xbox 360 or PS3 games and there is no doubt as to what the things on the screen are supposed to be.
Today, tabletop games are blending with video game elements to the point that it's getting hard to define one from the other. Is a play by post role playing game still a "table top" game if there is no table and the players are miles away from each other? How about the games being developed for Microsoft Surface? Will D&D on MS Surface be a video game or a tabletop game or something new?
I've played tabletop games in which the DM (or GM if you insist) had so many elements to create a shared look and feel for the game, that much less imagination was required. He had a music soundtrack playing in the background; recorded sound effects for spells and attacks; highly detailed minis for each creature; slick, highly detailed three-dimensional maps with walls, trees, water etc that emerged from the flatness of the table; and his rules were on "books" that were really .pdf files on his laptop (which was also running Firefox in another window so he could check the game's website for the very latest updates. He had set up the scenario we were playing with the aid of an encounter builder program and had created each of his creatures with a monster builder computer program. More than half of the players also had their laptops with programs that let them update their character sheets. They were even using a program that simulated dice rolls! If we hadn't needed to move our minis with our own hands and make decisions on what to do next, there wouldn't have been any "tabletop game" elements left. What kind of hybrid of video game and tabletop game do you call that?
I wonder if, in the future, there will be any distinction at all between these two types of games.
