         | 
         | It took me a few moments to understand what was happening - and
         | I ran into the house, bringing seveal more with me. One got

         | purple. I balistically punched myself in instinct until they
         | were all dead.
         | 
         | Then I learned how it works. You get tagged by the first
         | hornet. They have a little scent that is a 'tracer', and once
         | they see it, you're marked. Many, many times now I have been
         | tagged by an angry yellow jacket and run to safety before the
         | first stinging. There's about a second or two where your muscle
         | memory can sprint you out of their area, about 300 feet. Often
         | they will be found slamming the back door for several minutes,
         | trying to follow me.
         | 
         | They hate percussive vibrations. Walking, sledgehammering,
         | digging. They have two entrances to their nests, always a hole
         | in the ground. I own a bee suit and will just go dig it up with
         | a shovel now. I think it's still legal to do in my state. I
         | really hate yellow jackets, I'm sorry but I can't see what they
         | are bringing other than their rage.

         | 
         | This phrasing implies the premise is true, which I don't agree
         | with, so I am going to tackle 3 related questions:
         | 
         | - Why does /any phenomenon/ require explanation?
         | 
         | Because we are curious, and want to know how and why things do
         | what they do. Answers lead to more questions, to more answers,
         | in a loop of learning
         | 
         | - Why do all biological phenomena need an evolutionary
         | explanation?
         | 
         | Because outside of artificial selection, natural selection is
         | the only causal mechanism (outside of pure chance). Mitosis,
         | Miosis, and Mutation are the building blocks.
         | 
         | But much of that boils down to, "why is x the way it is?
         | Because chance". which is not very interesting, which leads
         | to...
         | 
         | - Why does bee sting suicide in particular warrant an
         | explanation?
         | 
         | Because under a naive understanding of evolution, it is a
         | paradox. Also, there was a time when proto-hymenoptera were not
         | eusocial, so how did they become eusocial? Those are really
         | interesting problems to look at.
         | 
         | You are right in pointing out that pop-sci evolutionary
         | handwavy explanations are a problem. But I don't think that is
         | common in the broad science in biology.

           | 
           | It is this particular cult-like insistence on the omnipotence
           | of natural selection that I challenge. Maybe there are other
           | causal mechanisms? In any case, it needs to be a falsifiable
           | hypothesis before we can call it "science". Can you prove
           | natural selection caused this particular feature of suicidal
           | honeybees? Even if we assume the author's natural selection
           | explanation makes sense, the causal mechanism is FAR from
           | clear.
           | 
           | My complaint is, biologists are wrong by limiting themselves
           | ONLY to the evolutionary toolbox instead of seeking other
           | causal mechanisms. And it looks like a conspiracy theory when

           | Then maybe the response should be, something is wrong with
           | the theory of evolution, i.e. the theory of evolution cannot
           | explain every feature of every living being, and we need not
           | pretend it can.

       | 
       | Very simply, animals learn to avoid such insects. The same simple
       | explanation - absent much of any concept of selfish or altruistic
       | behavior - probably applies to bees as well, regardless of their
       | colony structure. Once an animal is stung by a bee, it learns to
       | avoid bees, which reduces predatory pressure on all bees
       | (including bee mimic species).
       | 
       | The other primary role of the stinger is in defense of the hive,
       | i.e. colony survival. That's a more direct group selection
       | concept, as if the queen and some drones survive an attack on the
       | colony, new generations can be bred, so an aggressive pheromone-
       | trigger response by workers is likely.
       | 
       | Furthermore, one must always consider in evolution the role of
       | accident and misfortune. For example, walking upright in humans
       | is widely considered to have been a beneficial evolutionary
       | development, as humans were able to spread onto the plains and
       | were no longer limited to living in forests. So is the
       | development of a large brain. However, together those factors
       | make childbirth more difficult for human females relative to
       | other mammals. This wasn't a desirable outcome, more of a side
       | effect. Bee stingers lodging in some of their targets may be a
       | similar issue - i.e. an accident of evolution, not something
       | chosen by selection.

       | "Bees do not die after stinging. However, the stinger is left
       | behind in the victim's skin and the bee will eventually die
       | because it is attached to the bee's digestive tract and other
       | internal organs. When a bee stings, it releases a chemical called
       | pheromone that attracts other bees to attack. This is why it is
       | important to remove the stinger as quickly as possible to prevent
       | more stings.
       | 
       | Bees are essential pollinators and play a vital role in
       | maintaining the balance of ecosystems. They are important for the
       | health of plants and the production of food. Therefore, it is
       | important to respect bees and avoid disturbing them, as they are
       | a valuable and vital part of the natural world."

       | Because I come after them later with a can of RAID.

       | Normally worker bees live 4-6 weeks, but the winter generation
       | somehow is coded to live the entire 3 months.
