Fish, shrimp and algae - catch them together and you have instant seafood cocktail.

"Human civilization wouldn’t be where it is today if we hadn’t domesticated animals." In light of the ongoing Anthropocene, I ask you: where has subjugating our fellow creatures to our will brought us?

I don't know about JD, but subjugating creatures has brought me breakfast and lunch. As recently as last night, I got a very nice, warm, purring creature on my lap.

It's likely more common than you would think, I saw a nature doc once that showed baboons in India domesticating a wild dog to guard them at night on the huge landfill where they lived.

JD asks "I ask you: where has subjugating our fellow creatures to our will brought us?"

All sorts of benefits actually, including - but not restricted to - bacon sandwiches!

I haven't read the original article, but how do you/they come up with this as the "first experimental evidence for a hypothesised pathway for how this domestication evolved?”
This may be evidence of symbiosis, but there is nothing mentioned that is evidence for the 'pathway' of domestication 'evolving'. Given the short term memory of fish, it would seem the only way any such pathway might be proven is by replicating this behavior with freshly spawned fish that have not already seen such domestication. Was this part of the experiment?

Domesticating can simply mean taming an animal to use it for your benefit, which does sort-of seem to be what is happening here at a very basic level. Defending the animal so that it feels safe on your farm. However, generally one thinks of domestication as involving selective breeding -- intentionally causing desirable traits to be passed on to subseqent generations. Obviously that level of domestication is not going on here, but it is still interesting to see examples of animals or plants or various forms of life working together in a symbiotic relationship. Another example would be the anemone and the clownfish ... the anemone gives the clownfish with protection/shelter, while the clownfish provides the anemone with nutrients as well as scaring off predators.

Ants and aphids have a similar relationship.

Since when are insects not animals? For that matter, since when are humans not animals? It might be the first fish known to domesticate another species, but certainly not the first animal

Just another example of God's marvelous Creation and His imagination.
