Q

State some advantages of living in social groups

A
<ul>
<li>Easier to catch food</li>
<li>Increased Protection</li>
<li>Help finding mates</li>
<li>Help raising young</li>
</ul>
2
Q

What are some adaptations of living in a social group?

A

Social Hierarchy
Co-operative hunting
Social Defense

3
Q

Describe ‘Social Hierarchy’ and give an example of a species that features social hierarchy

A

Social hierarchy is where members of the social group are ordered in rank going from the most dominant individuals to the most subordinate
Examples: Chimpanzees, Wolves, Hens

4
Q

What are the two ways in which the social hierarchy of a group is maintained?

A
Ritualistic Threats(teeth bared, eyes staring)
Submissive Gestures(eyes covered, head lowered)
5
Q

What is advantages of social hierarchy?

A

<ol>
<li>Fighting is minimised, saving energy</li>
<li>Strongest genes get passed on to next generation</li>
</ol>

6
Q

How do animals improve their position in hierarchy?

A

<ul>
<li>By forming alliances</li>
<li>By challenging the dominant</li>
</ul>

7
Q

What is an advantage of cooperative hunting?

A
  • Larger prey can be tackled

- Everyone gets a share of food

8
Q

Give an example of a species that use cooperative hunting

A

Wolves,Lions

9
Q

What are the two types of cooperative hunting?

A

Running Down

Ambush

10
Q

What is the Ambush hunting technique?

A

Where the predators drive their prey towards other predators in wait
Example : Lion

11
Q

What is the running down hunting technique?

A

Chase after their prey to the point of exhaustion where they can catch the weaker ones
Example: Wolves

12
Q

Give an advantage of being in a group in relation to defence

A
  • More eyes to look out for predator
  • Safety in numbers
  • Harder to pick out individuals
13
Q

What are the three social defense formations?

A

Mobbing
Roosting in Circles
Travelling in a group

14
Q

Describe ‘Mobbing’ and give an example of a species that uses this technique

A

Mobbing is where the animals form a protective circle around the young and the enemies are driven off with a combined charge
Example: Musk Oxen

15
Q

Describe how roosting in circles can defend animals against predators and give an example of a species that employs this technique

A

<ul>
<li>Sleep with heads pointing outwards</li>
<li>Explode when predator approaches which scares them </li>
<li>Gives the animals the chance to escape while the predator is scared</li>
</ul>

Example: Quail

16
Q

Describe the formation for Baboons travelling in their group

A
  • Dominant males stay in middle close to females/infants

- Lower males raise the alarm if danger is spotted

17
Q

Describe the features of primate behaviour

A
<ol>
<li>Long parental care</li>
<li>Alliances</li>
<li>Dominance and Subordinate behaviours</li>
</ol>
18
Q

What does long parental care allow for?

A

Learning of complex social behaviours

19
Q

What is an alliance?

A

Social bonds that develop between individuals

20
Q

Why is it of importance that lower males/females form alliances?

A

To increase their social ranking

21
Q

Is the social hierarchy permanent or in a state of flux?

A

State of flux

22
Q

Give examples of behaviours seen in a ritualistic displays

A

Chest beating

Aggressive Verbal Sounds

23
Q

What are some advantages of ritualistic displays?

A
  • Reinforces dominance of head male

- Allows challenger to practice assessing threats

24
Q

Give some examples of subordinate behaviours seen in primate social groups

A

Grooming
