A possible explanation for greys/aliens having humanoid forms - Carcinisation, Nature has evolved creatures into crabs 5 times in a case of convergent evolution

https://en.wikipedia.org/wiki/Carcinisation

This may explain why highly intelligent lifeforms from other planets appear to be humanoid. It could be a preset within evolution where humanoids appear eventually in highly intelligent lifeforms. Convergent Evolution is the best argument for Grey Aliens being from other planets yet appearing the same as us (outside of the hybrid theory)

edit: please don't try to make me justify this theory. its just one of many possible theories to muse on. not one i subscribe to or hedge any bets on. its just another angle that this problem can be looked at from to broaden our thoughts

Molecular convergent evolution between echolocating dolphins and bats?

Many creationists claim that this study from 2013 showed how two unrelated species i.e bats and dolphins have the same genetic mutations for developing echolocation despite these mutations not being present in their last common ancestor.

I found two more studies from 2015 showing that how their is no genome wide protein sequence convergence and that the methods used in the 2013 study were flawed.Here are the studies:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4408410/?report=reader

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4408409/?report=reader#!po=31.3953

Can somebody please go through these studies and tell me what their main points are?(Since I'm not the best at scanning them).Can somebody also please tell me what the current scientific take is for this issue?Do bats and dolphins really share the same 200 mutations as shown in the 2013 study?or is this info outdated based on the two subsequent studies from 2015?

Edit:I have seen some of the comments but they don't answer my question.Sure,even if bats and dolphins share the same mutations on the same gene, that wouldn't be that much of a problem for Evolution.However my question is specifically "whether the study from 2013 which I mentioned above was refuted by the the two subsequent studies also mentioned above?"I want to know if biologists,today, still hold the view that bats and dolphins have gone through convergent evolution on the molecular level regarding echolocation or is that view outdated?

Amazing example of convergent evolution: the thylacine and the dingo independently evolved the canid body plan to fill the same biological niche. Their last common ancestor lived during the Jurassic Period. The dingo is more closely related to you than it is to the thylacine.

Types of convergent evolution (besides carcinization)

As I've ranted about before, I'm getting tired of the carcinization meme. So many people act like every single organism is going to evolve into a crab despite that kind of only happening with crustaceans.

There's a LOT of other interesting types of convergent evolution out there that don't have names yet, so I'm going to list them and come up with terms for them. (Though keep in mind that this is not a comprehensive list of every single example of convergent evolution out there, but something to encourage discussion.)

  • Volaticization: The tendency for many mammals and reptiles to develop some kind of gliding membrane, most famously flying squirrels and sugar gliders.
  • Echinization: Mammals developing their fur into sharp pointed quills, such as the unrelated Old and New World porcupines, hedgehogs, tenrecs, and echidnas.
  • Saltization: Mammals developing hopping feet and a long tail for stabilization. Most common in rodents such as kangaroo rats, jerboas, hopping mice, and springhares, but can also be seen in macropods.
  • Canization: Predatory mammals evolving into dog-like forms, can be seen in canids, hyenas, creodonts, mesonychids, and thylacines.
  • Rhinization: The tendency for large herbivores to evolve horn-like structures on their noses, such as rhinos, brontotheres, uintatheres, arsinoitheres, and ceratopsians.
  • Talpization: Mammals evolving into mole-like forms, which can be seen in true moles of the Talpidae family, along with marsupial moles, golden moles, and pink fairy armadillos.
  • Myrmecophagization: Mammals designed to feed on ants and termites, such as anteaters, pangolins, aardvarks, numbats, and echidnas. (There's also aardwolves and sloth bears, despite them not being quite as specialized as the others.)
  • Raptorization: Birds evolving sharp talons and beaks for killing prey. Examples include accipitrids, owls, falcons, and arguably Cariamiformes. Shrikes are halfway there, having the hooked beak but not the sharp talons.
  • Ciconization: Birds developing long legs and a long neck for wading, such as storks, herons, cranes, and flamingos. Azhdarchids could be considered a pterosaur example.
  • Spheniscization: Birds developing into streamlined wing-propelled divers, such as penguins, auks, the extinct plotopterids, and the extinct duck Bambolinetta.
  • Anatization: Another form of swimming bird design, except propelling with their feet instead of their wings. Examples include diving duck

Green Tree Pythons and Emerald Tree Boas, Convergent Evolution.

So GTP's and ETB's both have a very similar niche of a tree dwelling constrictor, having teeth great for latching on speedy prey. Both sport a very simular appearance with some minor differences (ETB's have white stripes that go down the spine whilst GTP's tend to have a more speckled pattern).

Where I find it really interesting is with juvenile coloration, Both go through a really gorgeous color change until adulthood. While GTP's Go from Red, to orange, to yellow, and to green, ETB's Reddish-orange coloration just kinda fades out into green, no yellow phase whatsoever.

A quick google search tells that the red juvenile coloration is for blending in with lower parts of the forest which makes a lot of sense.

I can't get this topic out of my head, it's just so fascinating how a python and a boa evolved to fill an extremely simular role, with only differences in pattern, head structure, and reproduction. I'd love to hear what others think of this topic.

Branched evolutions based on convergent evolution rather than divergent evolution???

I’m curious how people would feel about a branched evolution line where instead of the base form evolving into more than one form, there was multiple base forms that evolve into the same Pokemon.

I could see some cool ideas like two Pokemon with single typings both evolving into a dual-type based on their two types (like a fire-type and an ice-type both evolving into the same fire/ice-type), or maybe one line is more defensive and the other has higher offence and the final form’s stats change depending on which previous form it had.

I feel it could make competitive more fun as you wouldn’t know which base form the opponent’s Pokemon had so it’s move-sets, stats, maybe even typing could vary.

Some Pokemon I could see doing this could be Solrock & Lunatone becoming a Pokemon based on an eclipse, or the eeveelutions becoming an Arceus/Sylvally idea with their typing based on which eeveelution it evolved from

Just a thought I’ve had and am curious what people think?
