There are still isolating events, such as polyploidy, that can result in genetic isolation from the parent generation or any behavior or physical attribute that prevents coupling with the previous generation and is sudden in its onset.
You can probably get from asexual to sexual organisms if you mix and match your species definitions but that's probably pretty pointless.
>>8406354Yes, by most definitions.
You can try to argue "Muh subspecies" if you really want to try to make yourself look like an idiot but that's just taxonomy.
