Just what you need for the test

powerpoint


Arguments for evolution

Arguments for Evolution

  • 1 Fossil evidence – fossils determine age

  • 2 Anatomy – homologous and vestigial

  • 3 Embryology - recapitulation

  • 4 Biochemistry – DNA and similar proteins

  • 5 Distribution of animals – animals are

    different in isolated areas


Ch 8 the history of life

  • biblical worldview

  • Word of God

  • source of absolute truth

  • 1. creation (ex nihilo) Gen 1 – 11

  • 2. the fall Gen 3:17-19

  • 3. redemption Matt 1:21, Luke 24:46-47

Ch. 8 The History of Life


Ch 8 the history of life1

  • Non-biblical worldview:

  • theory of evolution

  • theory of cosmological beginnings

  • - Big Bang

Ch. 8 The History of Life


Ch 8 the history of life2

  • Non-biblical worldview:

  • theory of evolution

  • 2. theory of biological evolution

  • - less complex organisms

  • give rise to

  • more complex organisms

Ch. 8 The History of Life


Ch 8 the history of life3

  • Non-biblical worldview:

  • theory of evolution

  • 3. philosophy of evolution

  • - all things are progressing

  • toward a future perfection

Ch. 8 The History of Life


Ch 8 the history of life4

  • Results of believing

  • evolution theory

  • 1. man is not responsible to God

  • 2. man does not need a savior

  • 3. man is a highly evolved animal

  • 4. man’s religion = scientism

Ch. 8 The History of Life


Ch 8 the history of life5

Ch. 8 The History of Life

  • theistic evolution:

  • interpreting the Bible

  • to support evolution


Apparent age

Apparent Age

  • The earth was created fully mature, just as Adam was not born an infant.

  • If the world was created mature, then this could possibly throw off the age the geologists give to land formations.


Charles lyell 1797 1875

Charles Lyell 1797 - 1875

  • A geologist that stated that the earth was millions of years old.

  • Determined this by the rate of natural processes that take place at a predictable rate.


Thomas malthus

Thomas Malthus

  • An economist who proposed that resources such as food, water and shelter are natural limits to human population growth.


Ch 8 the history of life6

  • Lamarkian evolution 1801

  • Theory of

  • need

  • use & disuse

  • inheritance of acquired

  • characteristics

Ch. 8 The History of Life


Ch 8 the history of life7

  • Lamarkian evolution 1801

  • Objections

  • need doesn’t affect DNA

  • DNA not affected by use or disuse

Ch. 8 The History of Life


Ch 8 the history of life8

  • Always be ready

  • to give an answer

  • to every man

  • that asks for a reason

  • for the hope

  • that is within you.

  • 1 Peter 3:15

Ch. 8 The History of Life


Ch 8 the history of life9

  • Darwin’s theory of evolution

  • Descent with modification

  • common ancestor

  • 2. “survival of the fittest”

  • natural selection

Ch. 8 The History of Life

Descent with modification

Descent with modification

  • Common Ancestor??

  • Yes!!!

  • But not from a ancestor of a different species.


Ch 8 the history of life10

Natural Selection of Peppered Moths

Ch. 8 The History of Life


Ch 8 the history of life11

  • Darwin’s theory of evolution

  • Objections:

  • Variations of a Biblical kind

  • are not newly evolved organisms

  • Not always overpopulation

  • Not always the fittest that reproduce

Ch. 8 The History of Life


Ch 8 the history of life12

pangenes

genes that travel from the affected organ

to repro organs to be given to offspring

Ch. 8 The History of Life


Ch 8 the history of life13

Darwinism

changes due to need

Neo-Darwinism

changes occur due to sudden mutations

Ch. 8 The History of Life


Ch 8 the history of life14

Mutations

a change in the nucleotide base

sequence (DNA) of a gene

Ch. 8 The History of Life


Ch 8 the history of life15

  • Mutations do NOT cause evolution

  • 1 in 10 million divisions

  • usually harmful

  • All good mutations have to be in 1 organism?

Ch. 8 The History of Life


Ch 8 the history of life16

Ch. 8 The History of Life

Genetic Load: # of mutations

1,000s of mutations

would kill an organisms


Ch 8 the history of life17

Punctuated equilibrium:

evolution occurs rapidly

for a while and

then not at all

for awhile

Ch. 8 The History of Life


Comparative embryology

Comparative Embryology


Ch 8 the history of life18

Theory of Recapitulation

ontogeny recapitulates phylogeny

We go through stages of

evolution during

development

Ch. 8 The History of Life


Ch 8 the history of life19

Theory of Recapitulation

It’s a lie!!!!!!!!!!!!!!!!

Ch. 8 The History of Life


Homologous structures

Homologous structures


Arguments for evolution1

Arguments for Evolution

  • 1 Fossil evidence – fossils determine age

  • 2 Anatomy – homologous and vestigial

  • 3 Embryology - recapitulation

  • 4 Biochemistry – DNA and similar proteins

  • 5 Distribution of animals – animals are

    different in isolated areas

Fossils

Fossils


Ch 8 the history of life20

Ch. 8 The History of Life

  • fossil:

  • any direct or indirect evidence

  • of a once-living organism

  • that is embedded or preserved

  • in the earth’s crust


Ch 8 the history of life21

  • types of fossils

  • Preserved parts

  • - must be quickly placed under

  • pressure in rock-forming sediment

Ch. 8 The History of Life


Ch 8 the history of life22

  • types of fossils

  • 2. Preserved carbon (coal) “fossil fuel”

  • - plant material under

  • high temp & pressure

Ch. 8 The History of Life


Ch 8 the history of life23

Ch. 8 The History of Life

  • types of fossils

  • 3. Preserved forms

  • - casts or molds

  • - rarely in tar pits


Ch 8 the history of life24

Ch. 8 The History of Life

  • types of fossils

  • 4. Preserved tracks

  • - made in soft mud

  • which was turned

  • to stone


Ch 8 the history of life25

Ch. 8 The History of Life

  • types of fossils

  • 5. Petrification

  • - when water with

  • minerals penetrates

  • the solid parts of organisms


Ch 8 the history of life26

  • frozen wooly mammoth found 2007

Ch. 8 The History of Life


Ch 8 the history of life27

  • deluge:

  • to wash from

  • deluge theory of fossilization:

    most fossils were formed

    as a result of the flood

Ch. 8 The History of Life


Ch 8 the history of life28

  • Age of the Earth

  • Dating fossils with fossils?

  • * layers of the earth are assigned dates

  • * index fossils are assigned dates

  • * fossils found above index are “younger”

  • * fossils found below index are “older”

Ch. 8 The History of Life


Sedimentary rock fossils

Sedimentary Rock & Fossils

  • The oldest layers are at the bottom, the more recent layers are at the top.


Ch 8 the history of life29

  • Phylogenetic Tree

  • a line up of organisms

  • based on how they

  • might be related

  • similar appearance = common ancestor?

Ch. 8 The History of Life


Common ancestors

Common Ancestors ?

Ch. 8 The History of Life


Ch 8 the history of life31

  • Age of the Earth

  • Evolved over 4.5 billion years?

  • based date on…

  • * time needed for biological

  • evolution

  • * physical dating methods

Ch. 8 The History of Life


Radiometric dating

Radiometric Dating


Ch 8 the history of life32

Dating Methods

3. Decay or Buildup

* radiometric dating methods

(1) uranium-lead method:

half-life = 4.5 billion years

½ U decays to lead

Ch. 8 The History of Life


Ch 8 the history of life33

Dating Methods

(2) carbon-14 dating

half-life = 5730 year

½ of C-14 decays to nitrogen

Ch. 8 The History of Life


Ch 8 the history of life34

Dating Methods

assumptions of carbon dating

1. constant amount of C-14 vs C-12

2. equal C-14 formed & destroyed

3. C-14 decay rate constant

4. Constant amount of C-12 available

Ch. 8 The History of Life


Creation

Creation


Ch 8 the history of life35

  • Creation Week

  • Day 1 > light & darkness / day & night

  • Day 2 > firmament / waters divided

  • Day 3 > land & seas / plants

  • Day 4 > sun, moon & stars

  • Day 5 > animals of air & water

  • Day 6 > land animals & man
