Apterygote:
- no wings
- metamorphosis slight or absent
- one or more pairs of pre-genital appendages on abdomen

Pterygote:
- winged
- metamorphosis occurs
- no pre-genital appendages on abdomen

Exopterygote:
- simple metamorphosis
- pupa rarely present
- wings developed externally
e.g. cockroaches

Endopterygote:
- complex metamorphossi
- pupa present
- wings developed internally
e.g. butterflies

Insect reproduction:
1. requires synchronisation
- get together at the right time and relevent resource
2. overt displays
- for not attracting the wrong species
3. attraction to resources (food)
4. pheromones (female)
5. copulation
6. swarms (mostly male)
- got massive resouces in one location
- females come in and have opportunity to make

Selfish genes:
It promotes its own survival without necessarily promotes survival of the organism, group or even species.

Termite Castes
1. Primary reproductives (eventually become king and queen)
- winged adults
Roles: Establish colony

2. Secondary (supplementary reproductive if either primary dies)
- wingless adults

3. Workers
- wingless and sterile
Roles: Foraging, food storage, brood/nest maintenance

4. Soldiers
- wingless and sterile
Roles: Defense

Wasps
Spring: building new colony
Autumn: emerge from dying colonies
Winter: mating

Ants:
There are two female castes: queen and workers.
The queens and males have wings but lost after mating and then the male dies.

Poikilothermy:
The body temperature varies considerably in response to the environmental change.

Homeothermy:
- it maintains a stable body temperature by regulating metabolic processes.
- its body temperature is higher than external environment.

Thermoregulatory mechanisms:
1. Ectothermy
uses environmental heat sources to regulate body temperature
2. Endothermy
generates heat internally through high metabolic rate to maintain a high body temperature

The animal must balance the heat generation and heat loss to the environment in order to maintain a stable body temperature.

Reducing heat loss:
1. mammal hair is excellent for insulating heat loss
2. blubber, fine insulating hair and guard hair
This gives off no detectable heat when sleeping.

Overheat:
- move slowly and rest often
- excess heat loss where fur is absent and the blood vessels close to skin
- swim to cool down
- the fur can moult.

increasing heat:
1. shivering and exercise
- generate extra heat through direct muscular heat production

Flight
Pterosaurs:
- elongated metacarpal n phalange V
Bats:
- elongated metacarpals n phalanges
Birds:
- feathers are stiff so dont need extend limb

Swimming
- greatly reduced upper limb

Terrestrial Locomotion
Plantigrade: power/digging (hand)
Digitigrade: speed (hunting) (fingers)
Unguligrade: speed (escaping) (fingertips)
Power: Femur>tibia n fibula
Speed: tibia n fibula>Femur

Mammalian characteristics:
- vertebrates (internal skeleton)
- mammary glands (milk)
- high metabolic rate
- hair/fur
- nails, hoof n horns
- diaphragm
- throacic ribs (protect heart n lungs only)
Stance:
- erect
- legs held under body
- swing in vertical plane
- better for weight bearing

Dorsi-ventral flexure of the spine:
- spine flexes vertically
- seen in carnivores
