The feature is called Evolution based on hypothesis. Charles Darwin's Hunting hypothesis was that Bipedalism freed the hands for making tools. Rodman and McHenry's patchy Forest Hypothesis, bipedalism was ore efficient than quadrupedalism such that forests diminished and food resources also became scattered. Also not valid because bipedalism evolved in a forest environment.
Owen Lovejoy's Provisioning Hypothesis that males assist females more efficiently in procuring food; the need for food hypo, Birth spacing would be reduced.

A. Deletion
Explanation:
A deletion is simply the loss of a part of one chromosome arm. The process of deletion requires two chromosome breaks to cut out the intervening segment. ... A small deletion within a gene, called an intragenic deletion, inactivates the gene and has the same effect as other null mutations of that gene.
If this is a true or false question, the answer would be true. The double effect would refer to a situation where a beneficial action can have harmful side effects. It would mean that it would be fine to do an act if there are 2 effects, one bad and one good.
