16
Q

Theory of evolution

A

Life started from common ancestor

17
Q

Fossils
What is
Types

A

Preserved remains or trace of ancient organisms

Body fossils, trace fossils

18
Q

Formation of Fossils

A
  1. Buried in Mud or Sand
  2. Soft Part Decayed
  3. After millions of years
  4. Pressure sand to rocks
  5. Minerals deposited on skeleton
  6. Fossil formed
  7. Earth movement fossil up
  8. Further movement/Weathering exposes
19
Q

Other ways of Preserving

A

Trapped in Resin

Pressure forms Amber

20
Q

Fossils is evidence for

A

Arose from pre-existing lifeforms

More Complex and More Diversified with time

21
Q

Age of fossil, how?

A

Radioisotope Dating

22
Q

Limitations of fossils

A

Missing Links

  1. Soft bodies
  2. Decayed/ Eaten
  3. Imcomplete fossils
  4. Inaccessible places
  5. Condition cannot form fossils
23
Q

Other Evidences

A

Homologous Structure

Comparative Biochemistry

24
Q

Homologous Structure

A

Different Function, Same Design

Pentadactyl Limbs
From Common Ancestor and Modified

25
Q

Comparative Biochemistry

A

Similarity of Chemistry

  1. Amino acid
  2. Base Sequence of DNA

Note: Not DNA sequence, is base sequence

26
Q

Lamarckism

A

Environmentak changes create Needs
Modify body, Repeatedly used, Well developed
Acquired characters passed on to offsprings

27
Q

Darwinism

A

Natural Selection

Competition - Struggle for Existence
Variation - Survival of the Fittest
Favourable characters accumulated

λ favourable
Not favourable = Lower chance of Survival and Reproduction
After many generations, λ predominates.

28
Q

Natural Selection Answering

A

Variation exists.
λ = Higher chance of Survival and Reproduction
After many generations/ Repeated use
Proportion of λ increases

29
Q

Speciation
Answering
Types

A
  1. Isolated
    No interbred, No gene flow
  2. Different enviroments
    Variations
    Natural Selection acts on them differently
  3. After many generations
    Diversed variation
    Cannot produce Fertile offspring

Geographical Isolation - Physical Barriers

30
Q

Appearance
Repro

A

Long Feathery Leave

Spores
