There were ethical and practical reasons why Harlow could not use humans in experiments to identify the nature of attachment between human infants and their mothers.
Animals were not protected by the same guidelines on ethics. Therefore, Harlow could use monkeys in his experiments. The macaques are close to humans in evolutionary terms and in many behavioural traits so Harlow could gain insight which could transfer to human models.
We used to be monkeys over thousands monkeys turned to humans slowly
Monkeys i think
Monkeys do not directly evolve into humans. However, humans and monkeys do share a common ancestor. Over millions of years, evolutionary processes led to the development of different species, with humans evolving separately from monkeys. The evolutionary path that led to modern humans involved significant changes in brain size, tool use, and social behavior.
This question makes no sense, but slavery in the 1860’s had no use of machines.
Monkeys make sounds with their mouth, much like humans do. Monkeys make all different kinds of sounds depending on their moods.
I think monkeys evolve from humans or some other things.
Well sorry to tell you monkeys don't drive cars! the monkey u r talking about are humans as there origins r supposed to be monkeys and humans can drive due to there legs and hands . They drive in circuses and stuff...they just use smaller cars.
They're chimpanzees instead of monkeys in most drawings. Chimps are used because they're the closest primate to humans - they look almost exactly like us, so people find it humorous to see them doing things that humans would do, like dressing up in clothing and using human gestures.
Yes Monkeys have been known to store food/feces in their rectum, large intestine, and appendix. They frequently use this storage to throw fecal matter at other monkeys, and sometimes humans.
Yes, humans should humans in their art installations instead
The plural is monkeys. The monkeys were kept in cages. The plural possessive is monkeys'. The monkeys' cages were dirty.
The common animals Animal testers usually use are dogs and sometimes bunnies sometimes they can use all different kinds of animals because i guess different things happen to different animals. :) :D
