So students, let us solve this question.
00:02
So this question is a long answer type question and in this question we have to differentiate between proximate versus ultimate explanation, explanation of behavior which was given by tin burgeon.
00:28
So, and we have to take the example of the human infants cry, the human infants cry as an example to explain this.
00:44
And then also we have to mention the four questions given by tin bergen to explain the behavior of any organism.
00:57
So, tin bergen's 4 questions.
01:02
So, we will write proximate here and ultimate explanation here.
01:10
So, in proximate explanation of a behavior, we look at the mechanism of the behavior.
01:17
We look at the mechanism of the behavior.
01:24
And in ultimate explanation of the behavior, we look at the evolutionary relationship of that behavior.
01:30
Meaning we are looking at the fitness consequence of a particular behavior.
01:48
So when we take the example of the human infants crying, human infant or the human baby crying.
02:00
The proximate explanation will include the causes of crying.
02:04
What has caused the infant to cry? so under this causes of crying should come.
02:11
So what can be the causes of crying? it can be due to an external trigger, external trigger, example of which can be if the baby is cold, feeling cold or feeling warm or is hungry, doesn't have food.
02:34
So this, all of these can be considered as external trigger.
02:38
There can also be internal triggers for crying.
02:43
What can be the internal trigger? example of this can be limbic system.
02:52
Limbic system.
02:56
And when it comes to ultimate explanation of this behavior, then what are we going to talk about? we are going to talk about the fitness benefit.
03:06
The fitness benefit of this behavior.
03:09
Fitness benefit of the treatment of the treatment of the treatment.
03:14
Trait.
03:16
So what can be the benefit of this trait? it can trigger crying and infants can trigger defense mechanism or defense response in the caregiver.
03:32
Therefore this behavior is evolutionarily selected.
03:36
So this is how we can differentiate between proximate and ultimate explanation of behavior and we have taken the example of human...
