Is it possible for a human and another ape orangutan/chimp/bonobo to procreate? Similar to how a donkey and a horse can produce a mule or a lion and tiger can make a liger?. Another question on Quora

Algunas veces contesté a preguntas que me parecían particularmente tristes de la forma más clara posible. Ya que querían saber, que se enteraran bien, sin remilgos.
Esta pregunta sobre la posibilidad de entrecruzarse de chimpancés, bonobos y otros primates, cae para mi dentro de esa categoría, triste. No por la intención de conocer, sino porque los humanos, en nuestro afán de imponer nuestras reglas al resto del universo, hemos ido demasiado lejos. Sin duda ninguna los laboratorios han sido testigos de muchas atrocidades y hemos impuesto el sufrimeinto y la desnaturalización a muchos animales en nombre de la ciencia. Ciencia que a su vez ha sido el instrumento de ideólogos perversos y psicópatas.
No siempre. Pero sí en este caso. Pasen y vean.

I haven't known any non human ape intereted on making the experiment so far.

Oliver was once thought to be an humanzee, but serius research suggests that he was a common chimp. Oliver (chimpanzee)

Now, on a more serious tone, even when the answer is no, there are some courious facts regarding this matter, I learned about them the last time I was a2a about this matter, hybridazing human and other type of apes (one of these facts more than curious is hair raising).
The potential result of the cross of a human and a chimpanzee is called humanzee (humans always put ourselves ahead). There is a terrific article about humanzees in wikipedia, where you can read that:

  - Ilya Ivanovich Ivanov was the first person to attempt to create a human–ape hybrid. In the 1920s, he carried out a series of experiments to create a  human/nonhuman ape hybrid. Working with human sperm and female  chimpanzees, he failed to create a pregnancy. In 1929 he organized a set of experiments involving nonhuman ape sperm  and human volunteers, but was delayed by the death of his last orangutan. After that he couldn't carry more experiments. So far, that is the known state of facts regarding human-other apes hybridation (if there are more experiments, we don't know).

  - In 1977, researcher J. Michael Bedforddiscovered that human sperm could penetrate the protective outer membranes of a gibbon egg. Bedford's paper also stated that human spermatozoa would not even attach to the zona surface of non-hominoid primates (baboon, rhesus monkey, and squirrel monkey), concluding that although the specificity of human spermatozoa is not confined to man alone, it is probably restricted to the Hominoidea. (I understand that Bedford wasn't trying to create an hybrid, just investigating the ability of human sperm to penetrate in soem types of primates' egg cells).

  - Current research into human evolution tends to confirm that in some cases, interspecies sexual activity may have been a key part of human evolution. Analysis of the species' genes in 2006 provides evidence that after human ancestors had started to diverge from chimps,  interspecies mating between "proto-human" and "proto-chimps"  nonetheless occurred regularly enough to change certain genes in the new  gene pool:
A new comparison of the human and chimp genomes suggests that after the two lineages separated, they may have begun interbreeding... A principal finding is that the X chromosomes of humans and chimps appear to have diverged about 1.2 million years more recently than the other chromosomes.
The research suggests, that there were in fact two splits between the human and chimp lineages,  with the first being followed by interbreeding between the two  populations and then a second split. The suggestion of a hybridization  has startled paleoanthropologists, who nonetheless are 'treating the new genetic data seriously'.

  Now, what really scares me is that the X chromosome diverged more recently than the other chromosomes...why the X chromosome and the others don't?
