Echolocation and Pakicetus Page 1 of 1

Pakicetus . Artists drawing. By (© N. Tamura)

Pakicetus lived 50 million years ago and over an 11 million period years it is said to have evolved from walking on the land with maybe regular dips into the water to catch a fish and turned into the whale. This is depicted as fact. Museums have drawings of it , as do online sites showing pakicetus gradually turning into the whale.
Problem is though that it’s a little bit difficult to find out the evidence for this. There are in google searches a single scientist showing some drawings that is supposed to show that the nostrils on pakicetus must have moved along the face to become a whale.

We’d have to also consider in that transition from pakicetus to whale , that both male and female pakicetuses evolved separately into a male and female whale. That’s quite a stretch of the imagination. They then of course have to fancy each other and that’s not trivia.

A lot more is needed like all the chemical and fluid changes and brain changes and the bits and pieces to mate. So Mrs pakicetus would have to develope a womb to carry a baby whale. And Mr pakicetus would have to learn along with Mrs pakicetus how to show baby whale the skills of living in the sea.

Messy below and elsewhere .. wii tidy . My writing seems a bit military but just putting the thoughts down. It’s yours if you like writing. Even if you think it’s all nonsense.

This does not make sense when looking at the images above. It doesn’t feel right , and anyone would want some evidence. I can’t find anything convincing at all. The pakicetus image is of course an artists impression. Bearing in mind that evolution theory involves accidental random mutations with natural selection acting on it , then that is how pakicetus evolved into the whales of today. All the organs are channelling the blood , the new heart , new lungs and new brain setup and millions of other things that anyone could consider. And nothing along the way went wrong. So air was provided to the changing body with no mess ups along the way. Surely no one could tell any one else that that happened without showing the evidence.

Since pakicetus has flesh and blood and eyes and fancied other pakicetuses from their beginning , we might wonder why it would rely on random mutations and natural selection to turn into a whale and not use whatever it uses to exit in the first place to turn into a whale.

Over those 11 million years from pakicetus to a whale there are apparently inbetween body plans that have evolved. So the male and female pakicetuses evolved at the same time to work perfectly well together through natural selection to eventually be a whale. So the male pakicetus would have to evolve into a male whale at the same time as the female pakicetus evolved into a female whale. That’s 11 million years where nothing goes wrong. Both body plans changing several times.

The original pakicetus would not fancy a whale. But somehow 11 million years later the once male pakicetus is now a male whale and the female pakicetus is a female whale and they fancy each other. So the male and female pakicetuses evolved through natural selection in that time into male and female whales in the sea and fancy each other. There are several intermidiataries between pakicetuses and whales. In the fictitious drawings of them they look whole.

One remarkable adaptation pakicetus aquired along the way to being a whale was echolocation. That is the ability to make a noise under water through its evolved blowhole nose that goes out then rebounds off objects including food so that it can locate it or at least know what is out there. Sort of like being able to see things. (check as it may have had echolation as a pakicetus ,, not sure)

Other animals use echolocation too. The bat uses it in total darkness. “it sends out a screach from it’s mouth. Fortunately, most are too high-pitched for humans to hear – some bats can scream at up to 140 decibels, as loud as a jet engine 30m away. “To avoid being deafened by its own calls, a bat turns off its middle ear just before calling, restoring its hearing a split second later to listen for echoes.” https://www.discoverwildlife.com/animal-facts/what-is-echolocation. So to avoid being deafened by its own calls, a bat turns off its middle ear just before calling, restoring its hearing a split second later to listen for echoes.

Does all of this thinking just about echolocation on it’s own not at least make one ponder about the general acceptance that it is all about natural selection. Those bats that turn off their middle ear to avoid being deafened were naturally selected.

Who has the evidence and decided that Pakicetus turned into a whale. Maybe one scientist/researcher writing a paper?? Had a quick look and that quite might be the case. One crazy scientist decided it then another crazy scientist invented the idea that a blowhole moved along the top of the body to allow it to breathe and it is pure conjecture. You’d have to get permission to go into the underground basement of a German museum to see the fossils that are supposed to support the idea that any of this happened.

Then , did Pakicetus develop echolocation at all and did not turn into a whale. It is like finding a fossil of an otter and saying it became a dolphin simply because it could live on land and majestically swim in water. Or say there were only a few fossils and you find one fossil that shows it had a pair of eyes and another fossil of another animal that had two eyes and say one must have evolved into the other. So it as much about the limited evidence and then coming up with conjectures.

Natural selection could not do that. Natural selection is separate to the actual physicalities. Natural selection just means that things that worked best were more likely to carry on. If natural selection is pure conjecture , then what of evolution. Might as well say that doesn’t occur either. We are mostly relying on one or two peoples conjectures.

(conjecture .. a guess about something based on how it seems and not on proof)

It’s very hard to find the understandable evidence of this pakicetus turning into a whale online. Just videos and animations and words of how it evolved into a whale and one professor showing their find of a pakicetus fossil. If there was any evidence of this , it would be shown on television every day. If you do nothing else and like a ponder, read the skimpy conjectures put forward in any website like this natural history museum attempt to say that whales evolved from the land animal pakicetus. Absolutely no evidence at all. https://www.nhm.ac.uk/discover/when-whales-walked-on-four-legs.htm. All of the similar sites give no evidence. They just say that this happened.

The picture below is a tail of the sea animal Manatee. Looks a bit like a whales tail but apparently the manatee is more related to an elephant and not whales. The manatee and the elephant apparently evolved from some land walking animal but it wasn’t pakicetus. This land walking animal was more like a pig. It too supposedly paddled a bit in the water and turned into the manatee. But another line of it turned into an elephant. Can’t find any evidence at all. Just articles saying that some museum says that’s how it happened.
