They managed to procreate successfully. Can you say the same about yourself?
Fun fact, prior to the Cambrian explosion animals did not have hard parts. There is a theory in a book called "in the blink of an eye " that some animal evolved eyes followed quickly by the evolution hard parts and the Cambrian explosion. They’re were three phyla of animals before the Cambrian explosion and whatever the current number is now I think it’s like 28 after the Cambrian explosion which took place in a very short period of time. link to book

In The Blink Of An Eye
The Cambrian Explosion is universally referred to as biology's "Big Bang." About 550 million years ago, there was literally an explosion of life forms, as all the major animal groups suddenly and dramatically appeared. Why did it happen this way? Why didn't these creatures continue the slow, plodding pace of evolution, appearing only very gradually in the fossil record? Although several books have been written about this surprising event, none have explained why it occurred. Indeed, none were able to.Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Precambrian creatures were unable to see, making it impossible to find friend or foe. With the evolution of the eye, the size, shape, color, and behavior of animals was suddenly revealed for the first time. Once the lights were "turned on," all animals had to either adapt or die, and in a geological instant, the world became a very different place. A controversial theory but one that is quickly gaining ground, the Light Switch Theory promises to revolutionize our understanding of life and light. Drawing on evidence not just from biology but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating story of a young scientist's intellectual journey, and a celebration of the scientific method.
TotallynotJessicaThis is the peak of evolution. It’s been downhill ever since.

Hard agree.
Some evil cabal intolerant to vast variety of species orchestrated mass extinction so that now we are all this uniform fish-bird things.
I want to go back.
Go home, evolution, you’re drunk… or tripping balls on a heroic dose, sounds more like it.
bufalo1973Those are images made from the data recovered from their fossils. I guess they didn’t look like that at all. If the same process was done with human skeletons we’d have a very good laugh.
Sidyctism II.Those are trilobites, part of the arthropod phylum. They have exoskeletons (i.e no inner bones), so they would probably look quite a lot like their fossils. Comparing them to vertebrates like humans (or dinosaurs, or whatever) in this context makes no sense.
And an exoskeleton can’t have anything covering it because… ?
Because that’s what the “exo” part means.
It’s not a phase mom this is who I am
