regrowing missing body parts with extracellular matrix.
http://en.wikipedia.org/wiki/Extracellular_matrix
Due to its diverse nature and composition, the ECM can serve many functions, such as providing support, segregating tissues from one another, and regulating intercellular communication. The ECM regulates a cell's dynamic behavior. In addition, it sequesters a wide range of cellular growth factors, and acts as a local depot for them. Changes in physiological conditions can trigger protease activities that cause local release of such depots. This allows the rapid and local growth factor-mediated activation of cellular functions, without de novo synthesis.
Formation of the extracellular matrix is essential for processes like growth, wound healing and fibrosis. An understanding of ECM structure and composition also helps in comprehending the complex dynamics of tumor invasion and metastasis in cancer biology as metastasis often involves the destruction of extracellular matrix by enzymes such as serine and threonine proteases and matrix metalloproteinases.

less evolved
I think all species currently in existence are equally evolved.
I disagree. I'd say that the more closely a species represents its ancestors the less evolved it is. Or if you want to go further, the more closely related to every animal's common ancestor.
Another example is the snakes I mentioned. I think there are only two species of snake with vestigial manus and pes structures. Evolutionarily speaking, they are either behind or ahead of other snakes. We assume behind, because we don't think they're growing legs but even if it's the opposite that means other snakes are behind. Either way, one is less evolved.

I understand what you and DieCommie are saying completely, and measuring evolution by mutations and divergence from a common ancestor makes sense. I'm just drunk.
For a long time it was thought elemental carbon was only found in graphite and diamond. These two forms of carbon have been known for a long time, and it was generally accepted that they were the only forms of carbon having extended networks of C atoms in well defined structures.
In 1985 Richard Smalley and Harry W. Kroto detected a new form of carbon, C60. It was suggested it had the structure resembling a soccer ball; 12 five-membered rings and 20 six-membered rings arranged so that each five-membered ring was surrounded by 5 six-membered rings. It was named fullerene after R. Buckminster Fuller, who invented the geodesic dome. Some chemists refer to C60 as a "bucky-ball." The discoverers were awarded the Nobel Prize for chemistry in 1996. More fullerenes like C70 and C84 have been isolated and studied as well.
Fullerenes behave as if they have electron-deficient double bonds. Many different fullerene adducts with a variety of structures have been prepared. Cationic derivatives of these adducts, for example, bind tightly to DNA and can be used to visualize it by electron microscopy.
Fullerenes have been useful to the development of nanotechnology. The preparation of single-wall nanotubes has been based on fullerenes.

Babies can naturally regrow severed fingers.

There's been lots of cases where this shit happens, not gonna hunt for solid proof though..

When babies are born with an extra finger, there often is no bone inside.
In that case they tie it off with a piece of string, the finger dies and falls off.
Not to say they don't grow back sometimes, though. Just that I've seen the string thing.

You make it all possible. Doesn't it feel good?

Dolphins Have Developed Language:
NOVA video about dolphin intelligence: http://www.pbs.org/wgbh/nova/nature/how-smart-dolphins.html
More About Dolphin Language: http://www.telegraph.co.uk/earth/earthnews/5965626/Dolphins-talk-to-each-other-with-tail-slaps.html
Unfortunately you find conflicting information on dolphin intelligence because industries which make money from killing dolphins are often the ones contributing to documentaries about the animals. They need them to appear less intelligent and human-like than they are in order to maintain support for their business. Same goes for whales which also show some interesting signs of culture and cultural development.

Tardigrades, also known as Water bears have the amazing ability to enter a suspended animation for as long as they want.
http://en.wikipedia.org/wiki/Water_bear
"Tardigrades are able to survive in extreme environments that would kill almost any other animal. Some can survive temperatures of close to absolute zero, or 0 Kelvin (−273 °C (−459 °F)),[7] temperatures as high as 151 °C (304 °F), 1,000 times more radiation than other animals,[8] and almost a decade without water.[9] Since 2007, tardigrades have also returned alive from studies in which they have been exposed to the vacuum of outer space for a few days in low earth orbit.[10][1"

"Evolution. Evolution is the greatest force in the material world. Evolution will provide us the next step in intelligent life. But it will come from somewhere unexpected."
Today is the tomorrow you worried about yesterday. Yesterday is history, tomorrow is a mystery and today is a gift. Thats why its called the present.

Another case of "living in extreme environments"...
Micro-organisms discovered in underground caves survive in water with a pH of near ZERO. To me, this supports the fact that life on other planets is most likely to be found underground. That's where the water would be and that's where shelter is.
Martin Hanczyc researched a very thin line between LIFE and NONLIFE. They are called protocells, which are pretty much lifeless vacuoles, formed naturally, that support chemical reaction within. Very much like a cell, except that they they do not reproduce (among many differences). Martin Hanczyc produced very convincing cell-like behavior using laboratory made protocells, JUST CHEMICALS, that have very amazing border-line conscious qualities.
Makes you really feel like a slave to physics. Here's the LINK
If you've never heard of TED, watch the videos. FUCKING AMAZING, they got everything.

excellent thread 
A Mantis shrimp's 'club' can move so fast and is so strong that the impulse(i'm assuming, unless it actually aims for the glass?) from hitting an object can break a glass fish tank, hence it needs to be placed in a special tank to avoid this... And -
"In smashers, these two weapons are employed with blinding quickness, with an acceleration of 10,400 g (102,000 m/s2 or 335,000 ft/s2) and speeds of 23 m/s from a standing start, about the acceleration of a .22 calibre bullet"
