Can someone please give me the long answer on why humans cannot reproduce with chimpanzees, gorillas, orangutans, or bonobos?

    They can. Its all in constant repiticious sex between them. But given time and enough intercourse it'll happen.

    There's all kinds of warnings thoughout knowb though about mating with animals you know do it because hell opens its arms to ye all -wide-its a huge careless mistake and those that do it live to suffer!

    Different gestation times

    Even with 99% similar DNA, there's enough of a difference in that 1% to make it unfeasable.

    But the MAIN reason is we have different chromosome counts. Chimps have 24 pair, we have 23 pair. Either our common ancestor had 23 and one split at a time in the past as our lines diverged, or we had one fuse.

      Nope. Chromosome #2 was once 2 chromosomes that fused together.

    Scientifically, it could probably be done. Humans have one pair fewer chromosomes than other apes, with ape chromosomes 2 and 4 fused in the human genome into a large chromosome (which contains remnants of the centromere and telomeres of the ancestral 2 and 4). Having different numbers of chromosomes is not an absolute barrier to hybridization; similar mismatches are relatively common in existing species, a phenomenon known as chromosomal polymorphism. All great apes have similar genetic structure. Chromosomes 6, 13, 19, 21, 22, and X are structurally the same in all great apes. Chromosomes 3, 11, 14, 15, 18, and 20 match between gorillas, chimpanzees, and humans. Chimps and humans match on 1, 2p, 2q, 5, 7–10, 12, 16, and Y as well. Some older references include Y as a match between gorillas, chimps, and humans, but chimpanzees, bonobos, and humans have recently been found to share a large transposition from chromosome 1 to Y not found in other apes. This degree of chromosomal similarity is roughly equivalent to that found in equines. Interfertility of horses and donkeys is common, although sterility of the offspring (mules) is nearly universal (with only around 60 exceptions recorded in equine history).

    We do not know if humans can produce hybrids with gorillas, chimps, bonobos or orangutans, because no hybridization experiments have been performed for the past 70-80 years or so. Theoretically it is possible, but we do not know for certain whether it can be done until we actually try. Scientists who try such an experiment may well be arrested and even if he/she is not, it may be something we do not really need to know because how is the hybrid going to be treated? Is it officially a human with human rights, or is it to be treated like an animal and be kept in a zoo. How would you like it if your sperm or egg is used to perform such an experiment. How do you feel if your own offspring is to be kept in a zoo?

    What long answer? Somehow humans have 23 pairs of chromosomes, while those others have 24 pairs, and the change was so profound that the chromosomes don't line up and thus don't produce a viable zygote

      Wrong. Horses and donkeys have different chromosome numbers and they produce the hybrid mule.

    orangutans: We're too unrelated.

    gorillas: We're (probably) too unrelated. We don't mate with them and they don't mate with us, due to reasons of "ugliness." A hybrid would be at a severe disadvantage anyway, since the hybrid might be crippled compared with either of the parental types.

    chimps and bonobos: again, ugliness. We don't know whether we could hybridize with them. People aren't lining up to mate with chimps and chimps aren't lining up with people.

    The one chimp that was sexually interested in humans ("Lucy Temerlin") was never allowed to mate with them.

    Get a couple years of biology and genetics for the long answer, simple though Genetic incompatibility, same reason a chimp and gorilla can't produce offspring.

    They have terrible b.o., and never take you to nice restaurants.

    Incompatible genes. That is the full story.

    Peace.

    Why do we need a long one? It is simple organic chemistry. Our genetic patterns inside our cells DO NOT LINE UP and when the egg and sperm are combined...they are nowhere close enough to create a viable cell. It is essentially a chemical SHORT CIRCUIT and the cell can't divide and differentiate.

    Our genetic origins SEPARATED from a common ancestor MILLIONS of years ago.
