|2048 - Classic|
The game has been so popular that it has spawned a whole list of parodies, including variants based on the Fibonacci sequence, Tetris, Pokémon, and even a website where you can make your own 2048.
So create my own 2048, I did! I present: 2048 - Evolution Edition.
Mostly I created this for fun, but I hope that it can also be informative. I've written up short descriptions to go along with each tile, for those who would like to learn (or teach!) as well as play.
Whatever you do with it, have fun!
Choanoflagellates are single-celled organisms very closely related to animals. They look quite similar to the cells of modern sponges, and some even form small colonies. A colonial choanoflagellate-like organism may have been the ancestor of true multicellular animals.
Pikaia has a body very different from most animals that came before it. It has well-developed organ systems, a defined head and tail, and a flexible rod called a notochord running down its back. Later relatives would use the notochord as the foundation for a true backbone.
Astraspis is one of the earliest fish, and among the earliest animals with bones, including a true backbone. It has no jaws as fish do today, and its bones form mostly simple features. Its descendants would develop many advanced bony structures.
Tiktaalik is one of the first vertebrate animals to leave the water. It has a neck separating its head from its body, lungs as well as gills, and a flat head for peeking out of the water. The limb bones it inherited from its fish ancestors are developed enough for it to crawl around on land.
Seymouria has fully-developed limbs and lungs adapted for life on land. It also has special traits that allowed it to live its whole life away from the water, unlike its amphibian ancestors. Seymouria represents the transition between amphibians and reptiles.
Tritylodon inherited many land-dwelling traits from its ancestors, including the specialized amniotic eggs that it lays. But it also has specialized teeth, inner ear bones, and other traits typically associated with its descendants, the mammals.
Aegyptopithecus is a true mammal. It gives live birth and feeds milk to its young. It is also specialized for life in the trees, with long arms and grasping fingers and a great sense of balance. Many of its descendants would stay in the trees, but others evolved to walk upright on the ground.
Australopithecus inherited its specialized arms and legs from its tree-dwelling ancestors, but unlike them it has no tail and stands erect, walking on two legs across the ground. It has a large brain and dexterous hands, and might use simple tools like many apes do today.
