Inadvertent eDNA research
- Comment on sussvival instinct 1 week ago:
No actually. If you consider the plants to be Archaeplastida (glaucophytes, red algae, and Viridiplantae) or Viridiplantae (the green algae including Embryophyta) then the common plant ancestor is unicellular (greens and reds evolved multicellularity independently). If you consider the plants to just be Embryophyta (the land plants) then they already had highly specialized cells and looked plant-like before they split off from the rest of the green algae.
I’m not sure if the fungal common ancestor is believed to have been unicellular or multicellular but if it was multicellular then it would’ve been filamentous like modern multicellular fungi, rather than a sheet of cells

Fun fact: Animal embryos can be disassociated by depriving them of calcium (E-cadherin, the molecular that holds the cells together, needs to calcium to work) and then can be allowed to reassociate by adding back calcium. If you do this in early enough stages then the embryo will function and develop normally once reaggregated

Early animals were likely very similar to Trichoplax, but there weren’t Trichoplax. Trichoplax adherins is a modern species with just as many millions of years of evolution between it and the first animal as between us and the first animal. Just bugs me when people end up implying that orthogenisis is real

I think you misread wikipedia when it talks about its endosymbioses. Whole bacteria are found within an organlle (the endoplasmic reticulum) of Trichoplaxs.
That being said what you described does happen in a number of organisms (including ‘complex’ ones like nudibranchs). They steal the chloroplasts from the algae they eat in a process called kleptoplasty. Seeing as mitochondria and chloroplasts originated as endosymbionts that were then heavily integrated into their hosts, calling kleptoplasty a form of symbiosis isn’t that unusual.

haha the joke is that we all have to live under the thumb of imperial domination and its demands for conformaty while you have the privilege of being from the metropole

They’ve got it pretty good compared to some animals. Like at least they get to meet their partners or have sex at all

Yeah sure buddy, sportness is all made up by —let me guess— Big Sportness? Clearly you’re just mad that you’re not very sportnant.

Broke: The results of IQ testing are dependent on a person’s intelligence. Intelligence is an objective reality that can be observed and measured with IQ testing.
Woke: The results of IQ testing are independent of a person’s intelligence. Intelligence is an objective reality but complex and impossible to perfectly measure.
Bespoke: A person’s ‘intelligence’ is dependent on the results of IQ testing. Intelligence is a social construct and IQ testing is a means to reinforce it.

Also the impact risk corridor passes through states that are poorly equipped for large civil defence operations: Ethiopia and the CAR are in civil wars, Yemen is in a civil war with the majority of the country under the control of an unrecognized government, and the South Sudanese government is quite week—being at peace only for the last 5 years
- Comment on "Me Ug! Ug feel ACADEMIC!" 1 month ago:
Author-date systems create line noise that makes text hard to grok. Numeric systems (with or without footnotes) don’t have that problem. Honestly I don’t see the point of author-date. If a a paper is really important then it should be referenced in prose, otherwise “(Kowalchuck et al., 2018)” doesn’t tell you anything more than “[11]”; you’re still gonna need to look it up in the bibliography. And that looking up is actually made harder: finding [11] between [10] and [12] is easier than finding Kowalchuk between Kowal and Kowalski or whatever other names happen to be there.

what’s more sciency: the cycle that controls the vast majority of ocean ecosystems and one that even hobbyist aquarium keepers need to learn, or the niche one that smells like farts?

I’m a firm bug centrist—non-hemipterans can be bugs but they have to be from a terrestrial lineage.

Most species grow to half a millimetre. So they’re just barely visible to the naked eye; like a small spec of dust.
