I have questions about chimpanzees and bonobos?
1)what happnes when bonobos come across lots of food? 2)why do female bonobos g-g rub? 3) why do some primotologists think bonobos are the most appropriate ancestral models for early hominid behavior? 4)how does bonobo sexuality relate to the estrus cycle?
Anthropology questions please help !?
1. A male languar who chases off the resident male and takes over the group of females will often engage in infanticide because... C. the new male knows the infants aren't his and that the females will come into estrous sooner It is probably more that the behavior helps him pass on his genes. I doubt they are smart enough to realize that but the instinct is there because it increases his contribution to the future genes. 2. Alloparenting...parents other than the actual parents. C is best answer C. is mutual help in parenting or group parenting 3. artificial selection B. human intervention in evolution 4. Bonobo females regularly have sex with each other to build alliances and improve their dominance within the group hierarchy. A. True 5. Charles Darwin believed E. none of the above A. in the Law of Heterozygosity That is just when a single dominant chromosome is expressed. Darwin didn't really know about Mendelian genetics. B. in inheritance of acquired traits That is more Lamarkian. He believe those that inherited the best were most likely to survive. Lamark thought you passed down things that you aquired like a strong arm from being a blacksmith. C. in the double helix He didn't know anything about genetics. D. all heritable material comes from the father not true 6. Chimp studies have shown that chimps are not capable learning to modifying stones for use as tools. B. False They aren't well built for it but they could learn to break rocks. 7. Chimps engage in cooperative hunting. A. True 8.Co-dominance B. refers to the situation in which both alleles at a heterozygous locus express themselves phenotypically 9. crossing over D. recombination of genetic material during meiosis 10. Directional selection C is best. C. results in a change in the average value of a genetic trait, such as beak size, over generations. B. results in less variability by selecting out extremes It doesn't necessarily reduce variability and it tends to select the extremes not reduce them.
How do humans differ from chimpanzees?
A trained dog, such as a German Shepherd may easily understand and respond to some directions by humans even better than even a trained chimpanzee can. Despite relatively high intelligence of chimpanzees. But chimpanzees certainly do have other similarities to humans that no other animal does. Recently Bonobos have demonstrated the ability to understand human language to a high degree. But the bond between mother and baby has got to be one of the best examples how we are similar. True, it exists in other species but chimpanzees have an emotional bond with their offspring that is practically the same as ours as seen by direct observation. Chimps travel in troupes and are rather social. But chimpanzees treat outsiders as rivals and enemies much like humans have done throughout history. Bonobo chimpanzees are allegedly closer to human-like than other chimpanzees. Bonobo chimps prefer to make love rather than war. The males sometimes have sex with other males and the females do with other females. It is free love to the max. Bonobos have much less aggression, hostility and fighting than other chimpanzees.
Why are chimps more aggressive than bonobos when they are so closely related?
Why are chimps much more violent than bonobos?What does this say, if anything, about human behavior?Bonobos (and humans, as well) evolved to have a repetitive microsatellite at gene AVPR1A, related to the release of the bonding hormone oxytocin, which rewards pro-social behaviors. Chimps lack this piece of genetic code, so they don’t get the same hit of endorphins from it, and the resulting reinforcement of peaceful, trusting, cooperative behavior.[1][2]Although I would be very hesitant to draw any conclusions from observing the behaviors of a species that shares a common ancestor with us (be it chimps, bonobos, or single-celled organisms), it can at least be said that humans have the evolutionary capacity for compassion and cooperation rather than violence.Footnotes[1] Bonobos in the Garden of Eden[2] Microsatellite Instability Generates Diversity in Brain and Sociobehavioral Traits
Biological Anthropology: Could Bonobos be more closely related to Humans than Chimps, and if not genetically, what about evolutionarily?
We share a common ancestor with chimps and bonobos, that lived 6 million years ago. Chimps and bonobos split from a common ancestor 2-1.5 million years ago, separated by the Congo River. Thus, bonobos and chimps are more closely related to each other than to humans. The bonobo genome has been sequenced last year. The article is free access (The bonobo genome compared with the chimpanzee and human genomes). Interestingly, ~1.6% of the human genome is more closely related to the bonobo than to the chimp genome, but also ~1.7% of the our genome is more closely related to the chimp than to the bonobo genome. However, a caveat is that the genome of only one individual bonobo, a female, was sequenced so far. All these calculations of % similarity may change as more specimens are sequenced. Here is a nice Nature News and Comment article, though unfortunately they called the bonobo the "hippie chimp" ('Hippie chimp' genome sequenced).
If koko the gorilla, kanzi the bonobo and panzee the chimp could have a conversation in a room together what would they talk about?
Not sure… but Kanzi might well recognise Koko, because according to Wikipedia Kanzi began to use elements of sign language after seeing Koko use it in a video. (Kanzi’s original method of communication was via lexigrams on a keyboard.)Apparently the first time Kanzi was noticed using sign was when he signed “You, gorilla, question” to the anthropologist Dawn Prince-Hughes, who has in fact worked with gorillas. How Kanzi guessed that Dawn and gorillas had something to do with each other, I have no idea.In any case, it seems relevant to your question because(a) it shows Kanzi knows the sign for “gorilla”, which seems to be one of Koko’s favourite words,(b) it shows that Kanzi can ask questions. That’s something non-human apes supposedly don’t do. And something that could at least help to get a conversation started…
Which ape is more dangerous - a gorilla or chimpanzee?
Although gorillas are far more powerful, I’d be much more cautious around a random chimpanzee. Chimps are enough stronger than we are (roughly five times as strong, pound per pound) that we have no chance against them. I mean, does it really make a difference to your future if a gorilla can kill you ten times over, while a chimp can do it five? You can only die once. They’re both more agile and far quicker, and while chimpanzees are the smartest primates after our species, gorillas are no dummies.The difference is aggressiveness.After Jane Goodall’s studies, we learned that chimps will murder; they commit child abuse; they commit domestic abuse; they can suffer from serious mental illnesses. In other words, they’re as unpredictable as humans and have nearly all of our bad habits. Gorillas are vegans or near-vegans, whereas chimps have been known not only to scavenge meat, they’ll kill to eat. I don’t believe murder has ever been observed among wild mountain gorillas (don’t know about lowland ones). And while they’re also subject to various psychiatric disorders, I’d just feel more confident I could allay their fears and minimize possible aggression by going passive and submissive to them. A chimpanzee might very well be emboldened by our meekness.Circumstances would make the encounters variable. They’re so individual, as are we. An easy-going chimpanzee who’s had a good night’s sleep and a full belly is going to be in a much better mood than one who’s lacking those. For that matter, so am I.You and I are lucky, I believe, that we’re female. We’d present less of an obvious threat to any other primate. They do recognize human gender differences. As long as we stay away from a mother with her babies, we might be able to slowly back away, allowing us to reflect on the power and beauty of what we’ve just experienced.
