origins

the beginning

New cards
2
New cards

creationism

the idea that God created the universe and all life

New cards
3
New cards

informed interventionism

-a broader concept that also acknowledges God's intervention at other times in history -used instead of the word "creation" -came up by scientists

ex: the flood

New cards
4
New cards

abiogenesis

-life arose spontaneously from non-living matter many millions of years ago -made by T.H. Huxley in 1870 -people believed in the idea of it in 1600s by believing that meat made maggots

word = no life beginning or spontaneous generation

New cards
5
New cards

macroevolution

-all present life forms descended from a simple one-celled organism -believed by only evolutionists -major changes over time -hasn't been proved

New cards
6
New cards

spontaneous generation

the idea that life (living organisms) come from non-living matter

New cards
7
New cards

primoridal soup

-hypothesized that at some previous time, oceans were filled with CO2, methane, ammonia, hydrogen, and water -term made by Alexander Oparin

New cards
8
New cards

exogenesis

-a hypothesis that life began somewhere else such as comets and meteorites -term started when some scientists believed life was imossible to come from non-living matter

word = outside beginning

New cards
9
New cards

fixity of species

people believed that life on Earth was exactly the same as what was created by God during creation week

New cards
10
New cards

artificial selection

-breeders purposely selected plans or animals with desireable characteristics next generation -helps with the evolution theory

New cards
11
New cards

natural selection

pattern of variation, greater survival, and successful reproduction

New cards
12
New cards

microevolution

-small changes of characteristics over time -involves the process of evolutionary changes within populations -leads to sorts of variation that we see within species -believed by scientists and evolutionists

New cards
13
New cards

mutation

changes that occur when a gene is altered, damaged, or lost

New cards
14
New cards

panspermia

-suggests that life is widespread throughout the universe -some scientists believed in the hypothesis, others didn't because it still doesn't explain how life started

New cards
15
New cards

intelligent design

-not creationism -doesn't describe origins from a religious pov -mostly relies on scientific evidence, not scripture -theory that states that living things + other features in the universe are best explained by a "_____ designer"

New cards
16
New cards

Biblical worldview

-a theory of origin -viewing the world through the creation of God -informed intervention -can't be tested on scientifically -believed only in faith -many belief its a myth -many believe these accounts were borrowed from famous myths

New cards
17
New cards

worldview

-collection of attitudes, values, stories, + expectations about the world around us -it informs our every action (influences us) -ex: all scientists are influenced by this

New cards
18
New cards

Naturalistic worldview

-a theory of origin -belief in abiogenesis + evolution -doesn't believe that a higher being created the world

New cards
19
New cards

study of origin

when scientists develop theories on how life began by looking through evidence

New cards
20
New cards

theory

-wide acceptance based on scientific evidence -proven to be true due to perfomed experiments by scientists

New cards
21
New cards

scientific process

-observations that are made + experiments are performed -ex: helps scientists study how life began on earth

New cards
22
New cards

Doctors Gerhard + Michael Hasel

who found out that myths: creation happened through struggle Bible: creation happened through love

New cards
23
New cards

Francesco Redi

-Italian physician + biologist -experimented with abiogenesis in 1668

New cards
24
New cards

Redi's experiment

<p>-experimented to prove that abiogenesis is false -life doesn&apos;t start from non-living matter -the source of the maggots were from flies laying tiny eggs that we can&apos;t see</p>

Louis Pasteur

<p>-a scientist who later updated Redi&apos;s experiment with a special flask in the 1800s -even with enough oxygen, no live beings came out of the non-living matter</p>

20th century

when scientists started investigating where molecules came from

New cards
27
New cards

Alexander Oparin

-believed life came from the ocean

  • made the term "primordial soup" for it

New cards
28
New cards

Stanley Miller + Harold Urey

-experimented on abiogenesis by sealing in a container: water, methane, ammonia, CO2, + hydrogen (to resemble earth's atmosphere) -the theory was true back then, but is now false

New cards
29
New cards

Miller-Urey Experiment

experiment: -boiled water + several gases in a flask -sent electrical charges to it

results: -several types of amino acids in mix -its possible for molcules (organic model) -some amino formed weren't ones found in living organisms

New cards
30
New cards

Miller-Urey Experiment issues

-some molecules created weren't useful in life -some processes broke down amino acids and molecules too fast -Earth's atmosphere may have been different back then -amino acids are only right hand or only left hand seperately (mirror images). the experiment showed both right hand + left hand acids.

New cards
31
New cards

RNA world

-RNA = ribonucleic acid, found in living cells -some scientists believe theres an this type of world -suggests that life began with RNA formed molecules -false theory

New cards
32
New cards

Carolus Linnaeus

botanist who observed plants could become hybrids + cross between 2 species

New cards
33
New cards

evolution

-means: change over time -occurs in populations + groups, not individually

New cards
34
New cards

Charles Darwin

naturalist who made a theory that the evolution of new species occured as the result of natural selection

New cards
35
New cards

Points to Darwin's theory

-competition -variation -adaptation -selection

New cards
36
New cards

competition

when each species produces more offspring that can actually survive

New cards
37
New cards

variation

when each indicidual within a species is slightly different so there is a variety

New cards
38
New cards

adaptation

when some variations are more advantageous than others leading to certain individuals being able to survive better in their environment

New cards
39
New cards

selection

-when those that survive + reproduce pass characteristions on to their offspring, -making them better equipped to survive

New cards
40
New cards

Microevolution examples

-differences in beaks of finches -length of a giraffe's neck over time -predominance of light or dark peppered moths

New cards
41
New cards

two complex patterns of Intelligent Design

irreducible complexity + specified complexity

New cards
42
New cards

irreducible complexity

-a complex pattern of Intelligent Design -system that doesn't work if one part is missing

ex: a mousetrap

New cards
43
New cards

specified complexity

-a complex pattern of Intelligent Design -a system w/ a specific sequence to work

ex: a sentence - "esleap sasp eht eanmleond" = "please pass the lemonade"
