A Quote by Simon Conway Morris
The common ancient ancestor of mulluses and chordates could not possibly have possessed a camera eye, so quite clearly they have evolved independently. The solution has been arrived at by completely different routes.

Evolutionary biologists often appeal to parsimony when they seek to explain why organisms "match" with respect to a given trait. For example, why do almost all the organisms that are alive today on our planet use the same genetic code? If they share a common ancestor, the code could have evolved just once and then been inherited from the most recent common ancestor that present organisms share. On the other hand, if organisms in different species share no common ancestors, the code must have evolved repeatedly.
If you go to the octopus, and if you're not too squeamish, dissect it. You'll find that it has a camera eye which is remarkable similar to our own. And yet we know that the octopus belongs to an invertebrate group called cephalopod mulluses, evolutionarily very distant indeed from the chordates to which we belong.
The very large brain that humans have, plus the things that go along with it - language, art, science - seemed to have evolved only once. The eye, by contrast, independently evolved 40 times. So, if you were to 'replay' evolution, the eye would almost certainly appear again, whereas the big brain probably wouldn't.
We observe closely related species in sympatry and infer how they evolved from a common ancestor.
My younger daughter really loves makeup. She's quite good artistically. I could see her going into something possibly behind the camera - whether it's in film or still camera for editorial stuff - but she's very taken with makeup, and she's really quite talented for as young as she is.
We are all a complete mixture;yet at the same time,we are all related.Each gene can trace its own journey to a different common ancestor.This is a quite extraordinary legacy that we all have inherited from the people who lived before us.Our genes did not just appear when we were born.They have been carried to us by millions of individual lives over thousands of generations.
Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified.
The myriad valleys could have arisen anywhere on the landscape. The current positions are quite accidental. If we could repeat the experiment, we might obtain no valleys at all, or a completely different system. Yet we now stand at the shore line contemplating the fine spacing of valleys and their even contact with the sea. How easy it is to be misled and to assume that no other landscape could possibly have arisen.
By comparing the human and chimp genomes, we can see the process of evolution clearly in the changes (in DNA) since we diverged from our common ancestor.
Its important to remember that we evolved. Now, I know thats a dirty word for some people, but we evolved from common ancestors with the gorillas, the chimpanzee and also the bonobos. We have a common past, and we have a common future.

To sit patiently with a yearning that has not yet been fulfilled, and to trust that, that fulfillment will come, is quite possibly one of the most powerful "magic skills" that human beings are capable of. It has been noted by almost every ancient wisdom tradition
To think that humans evolved from lower species BUT the evolutionary process somehow came to a halt and we all arrived at the finish line simultaneously is to embrace a fiction possibly more implausible than Christianity.
We admit that we are like apes, but we seldom realise that we are apes. Our common ancestor with the chimpanzees and gorillas is much more recent than their common ancestor with the Asian apes - the gibbons and orangutans. There is no natural category that includes chimpanzees, gorillas and orangutans but excludes humans.
Very few recordings exist in which Hitler can be heard speaking normally. But in those that do exist, it's evident he possessed quite a warm, calm voice. It's a completely different tone from what he used in his public appearances.
'Psych' was so many different things, and they evolved in so many different ways over the years, and towards the end there, we were barely solving mysteries anymore. We were just paying homage to our favorite movies, television shows, and bringing through as many '80s icons as we possibly could.
