and cats evolved from scorpions.

I think one of the most interesting instances of evolution is how whales evolved from wolves. 

My roommate told me recently about a water ape from which a few scientist think humans evolved. Something about apes not instinctively holding their breath or swimming or something.

No kidding... I think this is genuine...

Humans evolved from a prehistoric SHARK from 300m years ago

Humans evolved from a prehistoric shark that roamed the seas more than 300 million years ago, say scientists.
The primitive fish named Acanthodes bronni was the common ancestor of all jawed vertebrates on Earth - including us, according to new research.

A re-analysis of a braincase dating back 290 million years shows it was an early member of the modern gnathostomes - meaning 'jaw-mouths' that include tens of thousands of living vertebrates ranging from fish to birds, reptiles, mammals and humans.

Acanthodes, a Greek word for 'spiny', existed before the split between the earliest sharks and the first bony fishes - the lineage that would eventually include human beings. Fossils have been found in Europe, North America and Australia.

 

 

Why is this significant? Well, it's complicated, but the bony fish that are in the sea lack certain senses, that we may have laying dormant in our system, which sharks do have.

BTW guys, I understand the Daily Mail is a tabloid. However, you'd be totally fucking surprised how often they carry cutting edge science stuff that other people simply overlook. I am not kidding you.

I've heard that too, something to do with the way our ears are formed and how our balance works on the same system as some underwater mammals

I didn't evolve from a freaky water fish thing

Some poker players evolved from sharks.

Their hands are nearly identical.

 I don't know much about monkeys, except there are old world and new world classes, and those are old world.

Some people still have that extra bump below the wrist, right? Their wrist bone protrudes, or something?

The Chimpanzee hand is still pretty close. So...

Stingrays, sharks. They are both the same group of fish, and they have electrical sense. Something called Ampullae of Lorenzini.

http://en.wikipedia.org/wiki/Ampullae_of_Lorenzini

The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled pores. They are mostly discussed as being found in cartilaginous fishes (sharks, rays, and chimaeras); however, they are also reported to be found in Chondrostei such as Reedfish[1] and sturgeon.[2] Lungfish have also been reported to have them.[1] Teleosts have re-evolved a different type of electroreceptors.[2] They were first described by Stefano Lorenzini in 1678.

Have you ever heard of frisson, or ASMR?

http://en.wikipedia.org/wiki/Frisson

Frisson is a sensation caused by audiovisual stimuli, related to ASMR and cold chill. However, it's a distinct phenomenon and typically expressed as an overwhelming emotional response combined with piloerection while listening to specific passages in music. The response is specific to the individual; stimulus that creates a response in one individual may not create a response in another.

Frisson is of short duration, usually no more than 4-5 seconds, usually pleasurable[1] and has been shown to correlate strongly to loud passages of music and passages that violate some level of musical expectation.[2]

It has been shown that during frisson, listeners enter a listening mode called "ecstatic listening" upon which skin of the lower back flexes, and shivers rise upward and inward from the shoulders, up the neck, and may extend to the cheeks and scalp. The face may become flush, hair follicles experience piloerection. This frequently occurs in a series of 'waves' moving up the back in rapid succession.

http://en.wikipedia.org/wiki/Autonomous_sensory_meridian_response

Autonomous sensory meridian response (ASMR) is a neologism for a perceptual phenomenon characterized as a distinct, pleasurable tingling sensation in the head, scalp, back, or peripheral regions of the body in response to visual, auditory, tactile, olfactory, and/or cognitive stimuli. The nature and classification of the ASMR phenomenon is controversial,[1] with a considerable cult following and strong anecdotal evidence to support the phenomenon but little or no scientific explanation or verified data.[2]

I am convinced those phenomenon are fully related to sensing bio-electrical signals in the body.

The same sense is capable of feeling SSRI withdrawl, or "Brain Zaps".

http://en.wikipedia.org/wiki/Antidepressant_discontinuation_syndrome

People with discontinuation syndrome have been on an antidepressant for at least four weeks and have recently stopped taking the medication, either abruptly or after a fast taper.[1] Common symptoms include flu-like symptoms (nausea, vomiting, diarrhea, headaches, sweating), sleep disturbances (insomnia, nightmares, constant sleepiness), sensory/movement disturbances (imbalance, tremors, vertigo, dizziness, electric-shock-like experiences["brain zaps"]), mood disturbances (dysphoria, anxiety, agitation) and cognitive disturbances (confusion and hyperarousal).[1][2][3] Over fifty symptoms have been reported.[4]

 

 

In the grand scheme of evolution, bio-electric sense begins with sharks. Plus the scientists are claiming we share the same jaw structure or something, so...

Do you have a better explanation as to why we feel the above phenomenons? I'm not asking you to explain why or how they happen, although, yeah, the CNS is largely a bio-electric system. I am asking you to explain how we feel the phenomenon.

I am not fully in agreeance with the Daily Mails missing link, as they are claiming the shark we evolved from, had no teeth.

Personally, we have two rows of teeth. Sharks are well known for having several rows of teeth. I don't know... do most mammals have a set of baby teeth and set of adult teeth? That's probably an interesting area to consider, although I have read that teeth a superficial way to determine evolutionary paths. I don't know why, but that's what I remember reading.

Dogs have two rows of teeth. We have two sets of teeth. Reptiles do not have multiple sets of teeth, and they are said to be protrusions of bone.

Here is a respectable article from Science Daily mentioning why we have one row of teeth and why mammals have multiple rows.

http://www.sciencedaily.com/releases/2009/02/090226160751.htm

A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study in the journal Science. When completely understood, the genetic program described in the study may help guide efforts to re-grow missing teeth and prevent cleft palate, one of the most common birth defects.

I am fairly sure that, perhaps us evolving from sharks is a commonly accepted idea. Perhaps the Daily mail is the only one running the story. Bet they have a senior science person on staff.

Remember everyone... try and turn to a reputable science tabloid. They will tell you the earths water came from a billion miles away from another galaxy...
