Not always, but some infertile individuals belong to their own new species, yes. It happens all the time with plant hybrids.<p>Plants can clone itselves so to be infertile is not the same as to be extinct for them. Infertile also means normally something like &quot;99,9999% unable to produce seeds&quot; but with enough time and a high number of tries, planets will align in the polinisation of two &quot;unfertile&quot; stems of the same plant. At the end seeds will be produced and the new species will exit the &#x27;trap&#x27; perfectly (or all DNA of the father will be discarded reverting to the original mother species). Is just a question of time.
