Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

Homo floresiensis--the so-called "Hobbit"--may not be a valid taxon. The type specimen may have just been a modern-type human with Down syndrome.

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

That argument's been dead for awhile now last time I checked.

Is there a correlation between Down syndrome and dwarfism? I really don't know, and would love for someone to enlighten me on this matter...

Yes- doctors use different growth charts for Down's because growth occurs more slowly.

Anyone who tells you the controversy with H. flores is over is wrong. I lean towards it being a distinct hominin but I am open to new analysis.


News about finding objective standards for identifying ADHD correctly in children, based on analysis of microsaccades during ongoing anticipation experiences. If this bears fruit it will be a big improvement over the (often falsely reporting) current method based on a doctor's analysis of the patient's activities and behaviour.

Also that medication substantially normalises these symptoms.

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

So any idea of T. sebesensis being something notable is out the window: http://markwitton-com.blogspot.ca/2014/08/thalassodromeus-sebesensis-pterosaur.html

Is the slow growth that slow though?
Also, I don't think that the cranium is indicative of Down...

How the hell do you mistake a turtle plastron for a pterosaur crest?

And then continue to mistake the two after someone has pointed out which it actually is.

(Sorry for double post.)

Not sure how I missed this until now... I really need to check Plos One more often....

Anyway, new Tapejarid* pterosaur, Caiuajara dobruskii gen. et sp. nov.:

I also plan on making a blog post about my thoughts on this thing. And I have a lot of thoughts on this thing. For a little hint, I'm not entirely convinced this is such solid evidence for lack of sexual dimorphism, or that they were social. I certainly don't think they were desert dwellers.

*I go by the Neoazdarchia idea, with Tapejaridae being monophyletic and being restricted to "Tapejarinae". I also believe Bakonydraco is a Tapejarid.

Sorry for necroing, but I think that sedimentological data, and (so far) absence of plants and insects, is making it quite plausible for the place to be a lake in the middle of a desert...

Poor migrating flock was probably half starved when they found the site. Most of them died from hunger after a few days or weeks there and the healthy ones went on. The lack of adults might indicate they were bullying the youngsters out of food... which means the biggest ones got away.

Plausible... Also could be a colony nesting near the desert lake...

Oh yeah. We just have to have a couple hundred dozen more space rocks from the kuiper belt and asteroid belt also to be planets and Pluto can have it's status back.

"Planet" is stupid. There are rocky planets, and gas giants. These should never be put under the same roof. Pluto is neither, Pluto is a space rock. NOT a planet even if there was such a thing.
