It is estimated that humans branched off of their common hominid ancestors about 5-7 million years ago along with which of these organisms?
a) chimpanzees
eliminate

b) giraffes

c) horses

d) platypus

Ans. (A). Chimpanzees.

The humans were evolved about 5-7 million years ago, along with chimpanzees from a common homonid ancestor, known as CHLCA (chimpanzee-human last common ancestor). The humans and chimpanzees were evolved from CHLCA as two different species by speciation.

This is why, chimpanzees are closest living relatives of humans as they both are sister species as they share a most common ancestor.

Thus, the correct answer is option (A).

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
