It's not a debate. They are the same species if they can breed and produce offspring which remains fertile over generations.

Geesh. This is exactly the circumstance where the animals would be defined as the same species.

When there is no definition of a species, determining interspecific gene flow would be quite difficult.

I do not mind fragmentary taxa for the most part, I mean hell i love megaraptorans and one of my favorite dinosaurs is Timberlengia. But the ones that get me are thanos and erythrovenator

Something i always wondered How can a taxa be a valid species if having this less can also result to it becoming dubious. One of the reasons certain families phylogenies is a hot mess is cause there's many fragmentary taxa of uncertain placements so maybe new rules would help

el otro día surgió en mis grupos una pregunta y la traigo a esta red social: piensan que pueden estimar cuánta gente se chaparon a lo largo de toda su vida? Un aproximado?

"Did you name a dinosaur "Thanos"?" "Yes" "What is it based on?" "Nothing" Seriously, I'm not someone who hates on fragmentary taxa, but... really? *This* is what we're calling Thanos?

Pasen sus Top tres Dinos favoritos. Los míos son: 1- Therizinosaurus. 2- Quetzalcoatlus. 3- Giganotosaurus.

No, que ustedes armen de hombres de paja y construyan un dios en el cual uno no cree es diferente.

no miente tremendo guionazo para los mamiferos poder reinar otravez la tierra solo porque un meteorito de la nada cayo en yucatan hace 65 millones de años

We might as well call it the Theory of Adaptation or the Theory of Genetic Drift since the idea is now so loosely connected to the utility of the theory as an explanation for current and past biodiversity. There is nothing here that is distinct as an example of evolution.

Proof is for math. We are talking about science. There may be good evidence, but because of the inherent flaws of experimental design and in the conclusions of scientists as individuals, there is no proof. I fear there is a portion of communication which is lost in translation

This is the exact reason why the public often buys the Science™️ spewed by reporters. Biology is not real, and it never provides proof. Biology is abstract, the application of the Scientific Method to the narrow portion of life which is both universally observable and testable.

That's the definition of a species. Different species bred can sometimes produce a hybrid like a mule or a liger. But it would be rare for the hybrid offspring the retain the ability to reproduce.

Evolution includes extinction. Adaptation by natural selection is not interchangeable with evolution.
