I didn't realise that sponges swarmed
Let me help.
Evolution (via natural selection for the fittest strains) occurs in **every single lifeform**.
It can be studied in viruses, bacteria, fruit flies, and all other living things. (Asexual lifeforms are trickier, but it still happen - in fact the development of sexual reproduction occurred precisely because it allow faster adaptation to changes in the environment.)
Faster-reproducing organisms are easier to study, because you don't have to wait for results.
This universality of application means that every free-living species obeys the rules of evolution. Weakness in individuals = low level of reproduction; strength = high levels.. This is true of sponges, elephants, slugs and honeybees. And sponges.
Higher levels of reproduction mean that your children occupy a greater proportion of the next generation than those of weaker individuals.
Again, true of ALL living things.
So populations are constantly rebuilt from parents who did best (at reproduction) in the previous generation. If having black skin suddenly becomes an advantage (an adaptive trait) then the numbers of black-skinned individuals increases in the population. Here is a classic example:
Peppered moth evolution - Wikipedia
Because evolution occurs in every single lifeform, and because the ways it works are well understood, you can make predictions about what will likely happen under particular circumstances. This is as true of honeybees as anything else. Honeybee populations will change in response to changes in their environment.
Those changes will be driven by the fact that those individuals who make the best changes win the race to make the next generation.
If however you throw various spanners in the works, the constant adaptation *toward health and strength* (that's what wins) fails. the result is sickness at best, collapse at worst.
Three guesses what the present spanners are....
