1

What is an proximate?

Deals with how
a particular behaviour
happens

2

What is an ultimate?

Deals with
why
an animal does something,
in
evolutionary reasons

3

Who was Niko Tinbergen?

A famous animal behaviour researcher who found there were two kinds of proximate and two kinds of ultimate explanation for animal behaviour.

4

Name the two proximate explanations:

1.What are the mechanisms that cause it? (mechanism)
2. Is the behaviour inherited or learnt?
(ontogeny/development)

5

Name the two ultimate explanations:

1: How is does it relate to the evolutionary history? (phylogeny)
2: What is the benefit to the animal's fitness? (function)

6

What is a hermaphrodite?

A hermaphrodite is an organism that has reproductive organs and produces gametes normally associated with both male and female sexes eg snails

7

What is a simultaneous hermaphrodite?

A simultaneous hermaphrodite (or homogamous) is an adult organism that has both male and female sexual organs at the same time.

8

Which animal is famous for self-fertilisation?

The banana slug

9

What is a sequential hermaphrodite?

Sequential hermaphroditism occurs when the individual changes sex at some point in its life eg clownfish

10

What is asexual reproduction?

Asexual reproduction is a mode of reproduction by which offspring arise from a single organism

11

What is courtship?

Animal courtship may involve complicated dances or touch, vocalizations, or displays of beauty or fighting to attract a mating partner.

12

Name the two different types of sexual conflict

Egg v sperm
Male v female

13

What are pheromones?

a chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behaviour or physiology of others of its species.

14

Name the different ways in which the transmission of sounds eg songs and calls varies

Attenuation,complexity,pitch,amplification and volume

15

What is intraselection?

Male to male competition

16

What is interselection?

Female choice

17

Name intraselection examples

Necking,Sumo fighting,escalation

18

Name the difference between antlers and horns

Antlers can shed whereas horns remain fixated to the skull throughout the animals life.

19

Name examples of interselection

Choosing based on physical appearance and general fitness.

20

What is sexual cannibalism?

Eating the mate after mating.

21

What is a social behaviour?

Activities among individuals that have fitness
consequences for both the actor as well as the
recipient(s) of the behaviour

22

Name the three levels of social behaviour

individuals, groups/populations, species

23

Example of minimum social contact

Black widows live alone until mating.

24

Examples of maximum social aggregation

Flocks, herds and colonies

25

Name some benefits of group life

Less likely to be eaten,protection,possible mating parteners

26

Disadvantages of group life

Have to share food/higher competition

27

What is a aggregation?

A group of individuals of the same species gathered
in the same place but not internally organised eg rattlesnakes gather during cold conditions to keep warm.

28

What is a colony?

a group of individuals belonging to the same species
which are highly integrated either by physical union
of bodies or by division into specialized zooids or
castes, or by both

29

What is a eusocial insect?

Castes with fixed division of labour eg Bees have queen bees and workers.

30

What is a mixed species group?

Groups containing individuals belonging to two or
more species which co‐ordinate their actions eg Saddle backed tamerins and red bellied tamerins.
