Baby - Western Lowland Gorilla (gorilla gorilla gorilla) is a mammal type animal. It inhabits rainforest and dense jungle. The weight of this animal is about 100kg - 200kg (220lbs - 440lbs) and average life span is 35 - 50 years.
Chimpanzees are our closest relatives, with whom we share 99 percent of our DNA. We are more closely related to chimps than chimps are to gorillas. Humans didn't evolve "from" chimps. Rather both species evolved from separate ape like species. Those who coined the term "evolved from" chimps or monkeys, or those who still don't differenciate between apes and monkeys are highly misinformed.
