Maybe not the most obscure, but I found it amusing when somebody pointed out how humans and warthogs have evolved similar sort of sparse hair in response to a savannah environment.

Praying mantids (Mantodea) vs Mantidflies (Neuroptera:Mantispidae) general bodyform

For those who don't know the difference, which one do you think this picture is of?


Praying mantids are Exopterygota, they have several nymphs stages before adults. Mantidflies are Endopterygota, they have a larval, pupa, and adult stage. There are many many different Orders of insects between them, but their bodyform is very similar. I think that's pretty obscure, I could probably go farther. Social insects of termites vs Hymenoptera?

They're both iguanid lizards, though, which makes one wonder if their common ancestor had some pre-adaptations for that kind of eye.

meh, it's obscure.

Hydrophilidae vs Dytiscidae (picture is Dytiscid)

the scavenger water beetle vs the predaceous water beetle. They are both water beetles, their bodies are modified ideally for water, the ventral side of their bodies are designed to lock in a "pocket" of air. Yet, they are two different Suborders of beetles, and both evolved TO aquatic habitats independently. Unless you can identify beetles very well, they even confuse amateur entomologists. The easiest way is that Hydrophilids have longer maxillary palps than antennae, and Dytiscids have longer antennae than maxillary palps.

Actually I believe chameleons are closer related to agamids, and anoles seem to be more convergent with day gecko's than with true chameleons in my opinion.

Yes, we know there are a lot of species of chameleon. Nobody said there weren't. The OP asked about CONVERGENT EVOLUTION. All the characters you mentioned are homologous because they're all derived from the same ancestors. FFS.

chameleons are of different families, same order. allthough they all developed similar traits. they are not all of the same line..

thats like one of the first posts. of the gold mantella and the golden dart..

Chameleons are all of the same order AND same family, Chamaeleonidae. Get it? Chameleon, Chamaeleonidae? ALL MEMBERS OF CHAMAELIONIDAE HAVE THE SAME FUCKING TRAITS YOU LISTED BECAUSE THEY DERIVED FROM A COMMON ANCESTOR.

Mantellas and dart frogs are not of the same family and are thought to have adapted to the same niche in different regions independently of one another.

Maybe he means chameleons and anoles, since some people call them chameleons, although that's already been covered by>>317111.

They are then broken down into the two families: Chamaeleoninae or Brookesiinae

brookesiinae are pygmies!
>> Anonymous
>>322541
And then those sub-families are further broken down into genera and species.

You... you really have no fucking clue how to read a cladogram or any grasp of taxonomy, do you? Do you even believe in evolution?

All chameleons didn't develop the same fucking traits independently.

Okay, this one is actually obscure:
Flying squirrels (Pteromyini) and Scaly-tailed flying squirrels (Anomaluridae). You might think based on the names that they're closely related, but you would be wrong. They're both rodents, but that's it. The Anomalurids aren't even sciurids, yet they look like squirrels, behave like squirrels and have gliding patagia like flying squirrels.

Believing in evolution is like believing in a kitchen chair.

But I agree with you.
>> Dr. Grissom !9GXd8p7Kds
Convergent evolution would be a feature of an organism that has evolved independently in the history of the species. A simple example would be wings in birds and insects. The ancestral species of the two did not have wings, they evolved independently. A counter example would be dragonflies and butterflies. They both have different wings, but their ancestors evolved the first wings, therefore they are not convergent. And that's why your chameleon example doesn't work.

The wings of birds and the wings of insects evolved independently and both serve the same function. It's not obscure but it's a perfectly good example of convergent evolution. They don't need to be similar in structure.

The eyes of cephalopods and the eyes of chordates are probably one of the better known examples but the brain and entire nervous system could be considered an example as well due to its sophistication and functional capacity not present in other molluscs.

Also, they have beaks similar to birds.
