They look kind of translucent to me, maybe the first of this kind of slug just had a digestive problem that didn't break down the chloroplasts, and the minimal energy through their bodies made those individuals more successful because they didn't need to eat as often as those who digested theirs. Yada yada other errors among the indegestible-chloroplast population showed further advantages when it's closer to the skin, they outcompeted their peers, etc.
replyThe article notes that the chloroplasts are like a larder that the slug can digest when needs be, so storage could have come well before photosynthesis was actually utilized.
replyOr maybe it was photosynthesis first. The chloroplasts just did their thing for a while, and slugs that digested them slower (and eventually ones that stored them) got more benefit than ones that didn't.
> please note I am not challenging the scientific truth of evolution
replyEvolution isn’t a matter of faith, you’re welcome to challenge it and try to poke holes in it.
While true, the predominance of evidence for evolution has reached the point that anybody attempting to argue against it would have to produce absolutely enormous amounts of self-consistent evidence that explains our observations better than modern theories of evolution. It's sort of like the laws of thermodynamics, or relativity, or quantum physics- if you found convincing evidence that any one of those was not accurate, and came up with a better explanation, it would both completely transform science, and open up new avenues for discovery.
replyAnd if you want to do that, you should probably get a deep set of experience; otherwise, it's not much different from a flat earther.
theres nothing stopping the entirety of existence as being experienced via wires connected to some brain matter suspended in a jar, one would have to disprove this issue at a meta level to conclusively state any given existential theory as true. therefore all existential theories including atheism are faith based, so to state any one particular theory as true is dogmatic and unscientific
