About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

A new study has now provided the first proof of an ant species that lacks both workers and males and consists exclusively of queens.

Ahhh, yes. Ants. My favorite 'missed the mark' discussion on my lack of hope in humanity was from my fellow anarchist friends. I am a staunch evolution nerd and they were like, 'nah - traits that favor trashy brute behavior aren't valid - just read Paul Kropotkin's Mutual Aid to have a better feels.' I did and got to chapter six before wanting to beat Paul's ass because his argument was basically ' trust in humanity and the world because insects like ants can get along'. Never mind the fact that if one ant doesn't share what it has with another than the colony will dismember it. Or how other animals fear ant colonies when they move into their territory. Hope in humanity not restored and I also hate ants even more.

Vibes say these are more ant-parasites than parasite-ants, but they're pretty interesting regardless. I was hoping to read about a clonal super-organism, but it seems like these supplant existing ant-queens, so I presume they are less collectivist than I was hoping. Still pretty cool.

"Now, the latest study shows that on top of killing the host queen, T kinomurai also reproduces asexually by producing clones of itself, and tricks the surviving host workers into rearing the offspring."

So do the clones then convince the workers to kill the original clone? Repeat until the colony falls apart because workers aren't being produced?

[–] tristynalxander@mander.xyz 2 points 5 hours ago

I don't know. I think queens have wings, so I presumed they flew off to kill a new ant nest, but maybe they split the nest or maybe there is some in-fighting. A good question for ant-biologists.

There's gotta be a point at which sexual reproduction comes into play, otherwise it's an evolutionary dead end

[–] Amnesigenic@lemmy.ml 3 points 4 hours ago (1 children)

If that were true then sexual reproduction couldn't possibly have evolved in the first place

[–] protist@mander.xyz 2 points 3 hours ago

When competing with an entire ecosystem of sexually reproducing species, it's an evolutionary dead end.

Cloning!

Note: Typically ‘workers’ are non sexually reproducing females for ants

They then analysed the queen ants under a microscope and found that their mating structures were not used, essentially indicating that the offspring were all clones.

After observing multiple colonies and multiple populations of the species, researchers confirmed that the species completely lacked workers and males.

“Our data therefore suggest that the life history of T. kinomurai is characterised by the unique combination of workerless parasitism and parthenogenesis, i.e., the ability to produce female offspring from unfertilised eggs,” scientists wrote in the study published in the journal Current Biology.

Yeah I read it, I'm saying that if an animal is only reproducing via cloning forever, it's an evolutionary dead end, because they will have completely lost the ability to adapt to environmental changes

[–] gid@piefed.blahaj.zone 10 points 15 hours ago* (last edited 13 hours ago) (1 children)

Not necessarily: mutations will still happen. But there will not be any genetic crossing over that will contribute to greater variance.

[–] protist@mander.xyz 1 points 3 hours ago

How many animals can you name that reproduce only asexually? The rate of evolution in an asexually reproducing species will always be significantly slower than a species that reproduces sexually, and over time it will be out-competed.
