The hypothesis that the origin of human bipedalism was linked to a shift from life in the trees to life on the ground in the grasslands of Africa Group of answer choices1. has been rejected recently subsequent to new fossil evidence. 2. has become a scientific law. 3. has been upheld by subsequent scientific data on human origins.4. was developed in consultation with genetic and fossil evidence.

4. was developed in consultation with genetic and fossil evidence.

Explanation:

Scientists have carried out exhaustive studies on the origin of bipedalism and from fossil evidence of more than 200 fossils among them from the Bishop Morotopithecus in which they find a genetic mutation which is closely related to the origin of bipedalism. Bipedalism developed in tandem with the increase in displacement activity over long distances and on the ground.

the answer is a) a shiprock was formed by igneous process
