Un-evolvable

via The Soap Box

In a previous blog concerning the Discovery Networks docu-drama Mermaids: The Body Found I discussed how it isn’t possible for mermaids to hide for this long and never be found. Well, there is a very good reason why mermaids have never been found, and why they most likely don’t exist in the first place: It’s highly unlikely that humans could have evolved into mermaids (at least in the short period of time as the film depicts).

Most mermaids (including the ones in the film) are often depicted as having their legs being fused together into a tail, with their feet having evolved into a large flipper.

While there have cases of infants born with their legs fused, this is not an evolutionary process, but a very rare birth defect called Sirenomelia, and most infants that are born this way either don’t live very long, or they are still-born. Those that do manage to live for several years after they were born are only alive because of modern medicine and surgical techniques. Considering this it should be considered highly unlikely that someone born this way could live long enough to have children of their own (if they were even capable of having children in the first place, and most children born with Sirenomelia are usually born with underdeveloped reproductive organs, or none at all) or could even survive in the water. Also, considering the rarity of this birth defect it’s highly unlikely that enough people could be born like this in the first place to create a sizable population.

The reality in concerning the evolutionary process when it comes to limbs is that limbs usually do one of two things: they grow or they shrink to the point where they disappear.

Dolphins are a good example of both of this.
