#1. Do chimps or gorillas in wild suffer from deadly to human illneses like cancer, ,diabetes, heart problems, or other diseases?
Those animals(I would add pig too) are very simillar in DNA to us ,so can anyone shed some light on it?
#2. If we compare health of any animals living in wild and eating food in wild and then take the same animal from ZOO and check for their health are there significant differences?
In the wild, the great apes (chimps, gorillas, etc.) do suffer from diseases such as polio, flu, the common cold, and so forth.
Few live long enough to get cancer - but it’s certainly possible.
One thing that doesn’t happen - female great apes do not experience menopause.
Do remember that in the wild seriously ill critters tend to become food for other, not-so-ill critters. An animal hampered by pneumonia will not be able to outrun lions, leopards, etc.
The health of an animal in a zoo depends a lot on the zoo. Up until the 20th century animals in zoos tended not to breed well, and survival rates weren’t that great. In the past 20-30 years, however, great strides have been made in learning the needs of various species and today animals at a modern, up-to-date zoo will most likely outlive wild litter-mates and be healthier far into that lifespan.
Comparing a newly-caught wild animal to a zoo animal… well, the average wild critter will tend to be stronger, with greater stamina, and free of gross defects (if it wasn’t, it would have become someone else’s dinner). The wild animal, though, will almost always have a fairly impressive load of parasites, both external and internal.
Zoo-bred animals may or may not have physical defects - an albino lion or chimp with tooth problems can survive quite well in a zoo where in the wild they likely wouldn’t last long. Zoo animals have fewer parasites. However, zoo animals can wind up suffering from obesity, diabetes, cholesterol problems and so forth for much the same reason people do - too much food, not enough exercise.
Might be most fair to say that the two groups have different health problems.
Yes, it happens all the time.
You can add pig in there if you want, but you’d be wrong. A pig’s DNA is no more similar to a human’s than any other mammal. So if you’re going to throw pigs in there, also throw in dogs, cats, rodents, whales, etc, etc, etc. I believe we’ve covered this in another one of your threads, though, so maybe you should go back and read that one again.
Animals in captivity tend to live longer than animals in the wild. A good example is Homo sapiens.
