What happens when you shake a swarm? This bundle of buzzing bees changes shape to form a more stable structure. This clever response is the result of individual bees following simple rules - a kind of emergent intelligence.

The queen is in the center of the mass . The swarm spreads under the plank so more bees can take a hold on the plank and each ''plank attatched'' bee has a shorter string of bees hanging from her , less weight to carry by each top bee . The harder you shake the wider they spread untill the swarm becomes so flat that the queen might be exposed . At that point the will fly off for sure. This has nothing to do at all with the center of mass .
This can be an argument against intelligent design. If men were indeed created by an intelligent entity instead of evolving, our testicles would have been flatter in shape instead of elongated to prevent stress and extreme wobbling back and forth, side to side. If there indeed is a God who created men, then that God is responsible why our testicles are shit as fuck. Not to mention, fucking ugly to look at.
Bees swarm when their population gets too big for their home, or occasionally when they start to dislike their current one. They split off half or all and one half makes new queens. Then the first born queen kills the rest of them haha. Bees are crazy. And as you could see at the end, while they're swarming, they are usually totally non-aggressive
I made it about 40 seconds into this interesting video before shutting it off and disliking it. There's over a billion YouTube videos and you're going to put some obnoxious whistling music over it. Pffft
Having low crime doesn't equal "intentionally do[ing] the difficult thing to improve the lives of others".
But anyway, I never said that not believing in god means you're likely to have selfish morals. I just said it's easy to convince someone to have good morals by convincing them god exists.
I said "if A, then B" and you took it as "if not A, then not B" which is not what I said.
That's not religion, that's called having good morals. If you went back in time and somehow convinced everyone to have good morals yet make them believe that there is no god(s), then it's still going to work
Read Dawkins's "The Selfish Gene". Natural selection can and does prodce (groups of) altruistic individuals. Because the thing natural selection ultimately acts on is the gene. So if genes that make the individuals of a group altruistic have a better chance of survival, then that's what will happen.
The metaphor Dawkins uses is to imagine the gene as a selfish entity in the process of evolution and when you look at it like that it becomes pretty clear why sometimes individuals will act in a way that seems counterproductive at first glance. Like, sterile workers in eusocial insects or other altruistic behavior.
Don't think so: each worker bee is just as related to the queens and drones produced at the year end as to any progeny of their own (if they weren't sterile), therefore the amount of their genes in the next generation is higher by not reproducing than by reproducing - because a bee colony is more efficient at producing progeny than a single bee. The Ant And The Peacock book explains it better than I can.
According to all known laws of aviation, there is no way that a bee should be able to fly. Its wings are too small to get its fat little body off the ground. The bee, of course, flies anyways. Because bees don't care what humans think is impossible.
Untrue: lots of research since approx 1998 has been unlocking how insect-scale aviation works, including induced vortices which are unlike the momentum-change/low-pressure interactions of propellors, rotor blades, and airfoils.
"Even though each individual bee doesn't necessarily know what's going on, by simply moving towards an area of higher stress, the colony as a whole acts intelligently." So how does each individual bee know that it should move to an area of higher stress if it doesn't "necessarily know what's going on"? Isn't this intelligent behavior in itself?
And my answer to that is: instinct.
The same way you know how heavy something is just by holding it, they feel the stress just by hanging on. Bees are reacting to the forces they individually feel, not to the forces the whole swarm feels. Although they might also be observing their neighbors, but that's probably as far as it gets.
It's not a sign of intelligence to follow one simple rule. "When in a cluster, move toward the stress." That's something that can be followed just by instinct. That's essentially what instinct is: reacting a certain way in a certain scenario based on rules you don't know.
Intelligence is making choices. Instinct is when a choice is already made for you through natural selection.
Scientists try to avoid anthropomorphization even to the point where they actually have some similarities to us. It's a duel edged sword. In one way it helps us to realize how different they are from us. In another way, it blinds us to how much they have in common with us.
Antidepressants are medications that can help relieve symptoms of depression, social anxiety disorder, anxiety disorders, seasonal affective disorder, and dysthymia, or mild chronic depression, as well as other conditions.
They aim to correct chemical imbalances of neurotransmitters in the brain that are believed to be responsible for changes in mood and behavior.
Depression Medications (Antidepressants)
These are the most commonly prescribed type of antidepressant.
Serotonin and noradrenaline reuptake inhibitors (SNRIs) are used to treat major depression, mood disorders, and possibly but less commonly attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety disorders, menopausal symptoms, fibromyalgia, and chronic neuropathic pain.
SNRIs raise levels of serotonin and norepinephrine, two neurotransmitters in the brain that play a key role in stabilizing mood.
Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants. They are effective in treating depression, and they have fewer side effects than the other antidepressants.
SSRIs block the reuptake, or absorption, of serotonin in the brain. This makes it easier for the brain cells to receive and send messages, resulting in better and more stable moods.
They are called "selective" because they mainly seem to affect serotonin, and not the other neurotransmitters.
