is insect a case of gene loss? originally same genes as humans but they lost like 30% of the genes and became more simplified creatures, then somehow copying these remaining genes further and futher evolving them and becoming very succesfull in their own nichesfirst there was ancestor of fish, somekind of weird worm which wasnt yet segmentedthen it gave birth to octopusafter octopus (and snails) had separated from the original worm, the worm changed into a segmented typethen the segmented worm evolved into fish (pieces of fish vertebrae are the segments)on the other hand the worm also evolved into insect ancestors some 700 million years ago, we would be talking about ocean creatures as insects themselves start on land and were never in the seacentipedes are very segmented, each segment is kinda like a piece of human vertebrae. on the other hand insects have less segments, only the head, middle body and abdomen so you can think of them being two pieces of vertebraehowever in insects the segmentation continues in their legs as wellonly centipedes, insects and spiders have so called arthropod legs, I am not entirely sure what part of human is corresponding to their legs, maybe lungs because in unsegmented worms the hairs that come out of them are the worms lungs and the hairs look like insects legs..in terms of genes, insects are a succesfull case of "lost of genes"they originally had all the genes a fish would have but they lost majority of it and became twisted into the form they are now, they dont contain an inner vertebrae but instead the vertebrae manifests itself as insect segmentation of the whole bodywhat continues to be same for fish and insect is a hollow notochord inside the creature (in fish its inside vertebrae, in insects its just stays there inside their body running from brain to anus, if a notochord is cut in half insect is paralyzed)
>>16023285I think you should stop having ideas
>>16023349nigga what are you jabbering about, my REAL nigga here figured out some kind of weird worm which wasnt yet segmented gave birth to an octopus! truly groundbreaking research.
>>16023285This is the kind of babble you can get behind
>>16023285no matter what, I will not eat ze bugs.my intestines can't digest chitin, as 99.99% of humans do.
>>16023459I hope you don’t eat mushrooms then
>>16023733I dont.A waste of money.
>>16023459>a primate can't digest chitinanon there are valid reasons to not eat ze boogs but chitin isn't one of them
>>16023996What else are in ze boogs except chitin?Bug intestine? Bug parasites?
>>16024010Ectoplasm, yes, ectoplasm
>>16024023No. I will not eat ze boogs intestine and parasites
>>16024010Parasites are the big one. If chitin were poison every monkey, ape, shroomer and 3rd worlder would be dead
>>16024035Chitin is not poison it just doesnt taste good and make my stomach churn when eating a significant amount.It the worst food, doesnt do anything, just take space and energy away from your body.
>>16024039You eat significant amounts of bugs?
>>16024039>>16024471human cannot digest chitin, it comes out as diarrheathis is why humans turned into wheat based lifestyle 10 000 years ago
>>16023285Maybe you have rooted the tree wrong?
>>16024583no, thats the real mystery of itits completely rightcomparison is between whole mitochondrial genome between the mentioned organismsthe first bilaterian animal likely had a mitochondrion which was transmitted to all its descendants and some lineages it mutated more than in some othersmutation speed is determined by lifespan: human lives maybe about 20 years before reproducing, many arthropods live for 1 year altough long lived species also existthis would indicate an insect genome mutates 20 times faster than a human but this is of course a quess
>>16024471I ate spider hot pot once as a darewasn't a nice experienceI can only tell you I didn't eat anything for the next two days
You are not even reading that tree correctly. Also mitochondrial gene evolution does not necessarily reflect other genes. And you are missing so many phyla representatives that this analysis is worthless. You need some echinoderms (closest invertebrate group), sponges, ctenophores (most distal animals), and actual INSECTS to make any kind of inference. Also, show nodal support values for this tree or it is fake and gay.
>>16025188how big spiders
>>16025207beroe forskalii is a ctenophore and you can clearly see its completely different from all other organisms in the tree
>>16025306as big as my hand.it actually had meat lmao.
