Genome mapping shows tunafish related to fish with completely different body shape, lifestyles

Deep sea fish such as the black swallower, with an extendable stomach that enables it to eat fish larger than itself, and manefishes, some sporting spiky fins like a Mohican haircut, are close cousins to mackerels and tuna despite having completely different body shapes and lifestyles.
What evolution theory predicted this? Note also: “Researchers: Tuna closer to seahorse than to marlin”
And this is a boring tunafish, remember? Tuesday’s sandwich.
‘Discovering that such radically different fish species are related is a bit like finding that a seal is more closely related to a cat than it is to a walrus!’ said Dr Matt Friedman of Oxford University’s Department of Earth Sciences, a co-author of the PLOS ONE paper. ‘By comparing genetic data with fossil evidence we were able to show that the origins of all these disparate groups lie in a period of rapid evolution that occurred around 65 million years ago. This is significant because this is when the Cretaceous extinction event that wiped out the dinosaurs also killed off many groups of large fishes inhabiting the open ocean.
It also shows that previous methods of classification of fish are probably all wrong, but we won’t be hearing that just yet. If at all.

Lungfish are considered closest relative of tetrapods (humans are tetrapods). Thus it would be something like the lungfish that wd40 argues is more closely related to me than it is to a tuna.
Well, here is a tuna:

Do you think a lungfish is more closely related to a tuna or is a lungfish more closely related to a human? Well, wd40 says, ” some fish are more closely related to you than they are to tuna”.
How did wd40 arrive at this strange conclusion? See: Lungfish and humans – famous novel has almost 100% similarity to Merriam Webster’s Dictionary.
Proving that all novels evolved by accidental shufflings of the dictionary.

Finding similar genes in organisms that are obviously widely separated from one another looks more like design than anything else. Designers reuse similar design elements in different products. Code writers copy code from other programs that may do radically different things. And that's the kind of thing we're seeing in living things. It's all chalked up to "convergent evolution" supposing the same thing evolves over and over in different creatures ... but if that's the case, we can't really tell from genetic analysis what is most closely related or descended from what. |
