How many years of cumulative evolution separate chimpanzees from humans? Group of answer choices 7-8 million years 2-3 million years 130-140 million years 130-140 thousand years 14-16 million years

7-8 million years

Explanation:

There is many scientific evidences present from which scientists concluded that the humans evolved from chimpanzees about 7-8 million years and the ability to walk on two legs evolved about 4 millions year ago. There are a variety of physical and behavior changes occurred in the human while evolving from apes or chimpanzees. It takes millions of years to change occurs in the DNA of an organism.

i'd say that the moon rock is about 2.2 billion years old.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
