No,it's not. That's what evolution is. It's primarily one form of life becoming another distinctly different organism. An ape that morphs into a human would necessarily still have been able to have sexual activity with another recently morphed humanoid ape OR one that remained as an ape.
I seriously think you don’t understand what are the definition of apes in biology.
What creationists and any theist that don’t have qualifications in biology or biology-related fields, is that existing species of one genus (tribe and family) can evolve into species of another genus (or tribe and family).
For instance, the species of modern domestic cats (Felis catus) and the species of modern lions (Panthera leo), belonged to different genera and different subfamilies, but they do share common ancestry at the “family” level - the family Felidae.
The cats belonged to the genus Felis, and the subfamily Felinae.
The lions belonged to the genus Panthera and the subfamily Pantherinae. Other big cats, like tigers, leopards, jaguars, also belonged to the same genus, Panthera.
Now despite belonging to the same family, cats (of today) can no more evolved into lions than lions can anymore evolved into domestic cats.
All lions (as well as leopards, tiger, jaguars of the Panthera genus, cougars of the Puma genus, all lynx species of the Lynx genus, and so on with different genera and their respective species) and all cats are Felidae.
Back to the ape.
Biology described and explained that different sub-families, tribes and sub-tribes, genera and species (and subspecies) of the family Hominidae, which Hominidae are more commonly referred to as “great apes”.
The great apes include all living genera and species, that fall under Hominidae family, so orangutans (genus Pongo), gorillas (genus Gorilla), both bonobos and chimpanzees (genus Pan) and humans (genus Homo) are all “great apes”.
There are only two sub-families: Ponginae and Homininae.
All genera of Gorilla, Pan and Homo falls under the Homininae lineages, while the genus Pongo (eg orangutans) is the only one that belonged to the sub-family Ponginae.
Regardless of the species that the genera, tribes and sub-families they belonged to, they are all great apes, including the species Homo sapiens.
But chimpanzees cannot give birth to humans, and humans cannot give birth to chimpanzees. You are assuming that species can jump from one genus to the other genus, from one generation to the immediate next. That’s not how evolution work.
Nor did humans evolved from chimpanzees. A much older species than both the Homo species and Pan species, diverge at some point (between 5.5 and 6 billion years ago).
Your mistake is thinking that modern human (Homo sapiens sapiens (35-40,000 years ago, which is subspecies of Homo sapiens) were around during this divergence. The oldest Homo sapiens have only been around 200,000 years. Homo sapiens, like that of the Neanderthals and Denisovans diverge and evolved from the Homo heidelbergensis, and different points in times.
What is am saying, that modern humans and modern chimpanzees weren’t around at the time of this divergence. Scientists are not certain, which species exist before this divergence, but it could be the 7 million year old extinct Hominini species, the Sahelanthropus tchadensis. Scientists cannot confirmed this yet, because they required more fossils, more data.
