yes but also no
convergent evolution is a thing, even pretty common (e.g. see crap like animals)
and while very rare and unlikely different species can "merge" especially if we speak about relatively simple live form through the more complex the more problematic and limited it gets
through that isn't the relevant point I want to make
The point I want to make is that the linear tree few of evolution often presented in documentations is wrong, species diverged but also reconverged all the time. E.g. neanderthal might have died out but to some degree also mixed into what later became homo sapiens sapiens.
This might seem irrelevant for anyone not studying this topics, but it isn't as the tree one survives the other dies out view is often one of the building blocks of white supremacist race theory (which theoretically also doesn't make sense even if evolution is a clean tree as they extend concepts from inter-species relation ships to ethnic groups which average difference in DNA is too small to call them different races, but it's not like such people care about since).
