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.

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?

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.
