Evolution
- Surving in different
environments
- survival and ability
to breed
- Charesteristics
called adaptions. E.g
behaviour, function
- Structural
- Physical
- Colour: camouflarge
- Weapon: sting
- Apearance:
Bigger,
mimic
- Colour: camouflarge
- Physical
- Functional
- function of internal
organs
- depends on immediate
environment E.g chamelion
- depends on immediate
environment E.g chamelion
- function of internal
organs
- Behaviour
- animal acts: nocturnal,
still, store food
- animal acts: nocturnal,
still, store food
- Plants: narrow leaves
- Purpose = survival in
environment
- no favourable
characteristics die out
- others survive- offspring inherit-
favourable common
- others survive- offspring inherit-
favourable common
- allows variation
- enivronmental survival
- difference in genes,
chromosones- inheritance
- genetic mutation
- diet, avaliaibilty , habitat

- Natural selection
- process in which

charesterisics

- survival and ability
to breed
- Theories of evolution/
beggining of life
- 1700 belief organisms/
chareteristics fixed
- George Buffin: capable of
change
- Eramus darwin-
change to another
- Charles Darwin: grandson
- different species-
common anscestor
- Galapogas island-
naturaul selction
- 14 species finches
- similar colour-
different body
- similar colour-
different body
- naturaul beak variation
- birds suited- survive- offspring
- 14 species finches
- denounced- god
- Galapogas island-
naturaul selction
- first with scientific proof
- alfred russel wallace-
same conclusion
- inferior killed off
- published paper with darwin 1958

1st detailed
- simlilarities and
difference- only if species
are elvoving
- adapated through struggle to survive
- organs used= stonger 'not
used= weaker
- changes passed on
- no evidence- modern geneitics show
aquireed characteristics cannot be inerited
- inheritance comes from chromosones
- inheritance comes from chromosones

- Types
- Speciation: process of
forming new species
- occurs over long time
- combination: natural selection
and other eg isolation, mutation
- 1. geographic isolation
- earthqauke, group split
experiencing diff circumstances
- earthqauke, group split
experiencing diff circumstances
- 2. Natural selection
- over time each group will change
- sub species-look diff, still
interbreeed
- sub species-look diff, still
interbreeed
- over time each group will change
- 3. Reproductive isolation
- isolated long enough- can't
interbreed because of change
- new species
- new species
- isolated long enough- can't
interbreed because of change
- 1. geographic isolation
- Divergent
- new species-common ancestor
- finches
- adaptive radiation:
organism adapt to new
enviro
- finches
- new species-common ancestor
- convergent
- elvove and develop similar adaption
- similar enviro, lifstyle
- similar enviro, lifstyle
- elvove and develop similar adaption
- parallel
- related species - similar features
while seperated
- look alike and common ancestry
but in diff locations
- look alike and common ancestry
but in diff locations
- related species - similar features
while seperated
- occurs over long time
- Speciation: process of
forming new species
- fossil record
- palaentology:
study of fossils
- preserved evi past life
- actual remains of
