How did human creatures get transformed into a social being
Volgvan

Answer:

To increase our survival chance.

Explanation:

In order to survive in the harsh environment, Humans generally need to do 2 things : fulfill our basic needs and defend ourselves from external threats.

Both of them would be much easier if Humans are working together in a group.

For example, during hunter/gatherer eras, catching animals that can run faster than humans will be much easier if we have teammates to surround the prey rather than working alone.

On top that, being in a group also provide better protection from the attacks of wild animals or other humans. This is why human creatures get transformed into a social being.

zepelin [54]

Answer:

75%

Explanation:

In order to understand this question you need to understand the matching law first. The matching law provides the density of reinforcement or the rate of reinforcement if more than one response is available simultaneously to the individual. Here, two responses are available which are left key, 60 reinforcers per hour, and right key, 20 reinforcers per hour. This provides the ratio between the two reinforcers which is 60:20 or 3:1 in favor of left key. Here, one has to make a prediction only for left key and based on 3:1 ratio it can be said that 75% of pigeon will make their responses on the left key.
