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...

Interesting theory, but I am not Jim West.

Like from the 1999 Will Smith feature film Wild Wild West?

Like the guy who invented durian.

Durian Durain started all of this?
True artists!

I really don't understand the need to pin it down as one ancestor. Horizontal gene transfer would've been incredibly common(exacerbated by the viruses and low defense against them). Trying to play like there was one organism that collected all the features ignores the features just getting wholesale transplanted later.

Continuously adding the Evolutions pile of evidence is a good thing

[–] roguetrick@lemmy.world 2 points 8 hours ago

I just think it's a framing problem. In bacteria and archaea(particularly in the early periods) the genes themselves are what were impacted by natural selection and they would propegate between species based on the gene's fitness alone. "Ancestor" is a bit of a misnomer and it's very hard to ever say you've developed a timeline.

[–] TachyonTele@lemm.ee 1 points 8 hours ago

Because so far the evidence points to everything having come from one ancestor.

Did you read the article? God's name is Cellular Bill.

I believe it's in the Bible too. Deuteronymy or maybe it was one of the Psalms.
