Did Bilaterians and Vertebrates arise thanks to larvae accidentally becoming sexually mature while still in their larva stage?

2021.11.29 18:19 doboladora Did Bilaterians and Vertebrates arise thanks to larvae accidentally becoming sexually mature while still in their larva stage?

This is a fascinating thing to think about in regards to the evolution of animal life on Earth.
Firstly, for the evolution of Bilaterians, there is the "Planula Hypothesis" which states that Bilaterians evolved from the bilaterally symmetric larval stage of Cnidarians, their closest relatives, called Planula, where the larva somehow acquired the ability to reproduce without turning into a polyp or medusa as it reached adulthood.
Secondly, the closest relatives of Vertebrates are Tunicates, Chordates which have a tadpole-like larval stage, but as they reach adulthood, they morph into a sessile filter feeder with no nervous system. The ancestors of Vertebrates were Tunicates which accidentally became sexually mature while still being motile tadpoles, becoming the first fish.

2021.11.29 18:19 RandomAxolotlGuy Moray Eel holes and shells/hermit crab shells.

All right. so one time, when I was playing Deeeep.io with my friend, my friend was a swordfish and was hiding in a moray eel hole. but then suddenly, a shell spawns inside and pushes my friend outside and gets killed by the whale. what I am trying to say is: maybe we could make so shells don't spawn inside moray eel holes so they don't push players down and experience what happened to my friend?

2021.11.29 18:19 awaterproof Ledn.io, Plataforma para ganar interés en BTC y USDC (+$50 USDC) - [Coinbase]

Hola a todos. Me gustaría recomendarles una plataforma para generar interés en BTC y USDC:
Ledn.io está dando $50 dólares. Es una empresa canadiense apoyada por Coinbase. También cuenta con prueba de reservas (ni siquiera Binance hace eso). Por lo que estamos hablando de una alta seguridad.
Están regalando $50 dólares en USDC para los usuarios nuevos, quienes inviertan $75 USDC o 0.0015 BTC*. Lo cual no está nada mal, teniendo en cuenta que antes sólo daban $10. Sin embargo, la promoción sólo es válida hasta el 31 de diciembre.
Sus intereses son bastante buenos:
+6.25% anual en BTC
+9.50% anual en USDC
En comparación con otras plataformas.
Puntos en contra:
- Es centralizado
- Te cobran $10 USDC al retirar (altas comisiones de ETH)
Puntos a favor:
- Altos intereses.
- $50 dólares.
- Apoyado por Coinbase, en Canadá y cuenta con prueba de reservas.
- No te cobran comisión por sacar BTC.
Me encantaría conocer su opinión, les dejo además mi enlace de referido por si desean recibir los $50 USDC (no se sientan obligados):
https://platform.ledn.io/join/c11890ece998babe165370a0962b2328
Mi intención no es hacer SPAM, pues considero genuinamente que varios de ustedes podrían estar interesados en esta plataforma. Yo llevo usándola desde Julio de 2021, y no he tenido ningún problema. Los intereses se pagan el primero de cada mes.
Saludos.
*Detalle: Para obtener el bono por referido, debes abrir una cuenta en Ledn y luego depositar y mantener un mínimo de 75 USDC o 150K satoshis (0.0015 BTC) en una Cuenta de Ahorro de Ledn durante 15 días o más. Este depósito debe realizarse dentro de los 30 días siguientes a la apertura de la cuenta.

2021.11.29 18:19 Dwann- Does the MSI B550M PRO-VDH WIFI compatible with R5 3600? I heard many issues about that.

I have R5 3600 and recently i have got the B550M PRO-VDH WIFI. I installed with no problems. Than, i pressed the power button and it didn't boot. Therefore, i entered the boot option screen and the i have got the meaningless error beeps. By the way, when i clicked anything on boot option screen it was restarting pc.
Is that common problem? What should i do?
