Origins of life Flashcards
1
Q
Religious explanation
A
- rely on revelation in the form of scripture
- genesis is the first book in the bible and tells us how the world and the life on it came to be
- there are two stories within genesis that talk about the origins of life; genesis 1 and genesis 2
- can be understood either literally or symbolically
2
Q
Genesis 1
A
- religious account on the origin of life
- on the sixth day God created “man and woman in his own image”
- they are in charge of the whole world and are special to God
3
Q
Genesis 2
A
- religious account on the origin of life
- God formed man of dust from the ground and breathed life into him
- after Adam he created vegetation and animals
- God then created woman from mans rib and breathed life into her
4
Q
Literal interpretation of the religious explanation
A
- the bible is God’s word and God’s word is true
- humans had life breathed into them by God
- life was not formed gradually rather species are fixed and do not change gradually over time but remain as God made them (goes against evolution)
5
Q
Symbolic interpretation of the religious explanation
A
- God created the Earth and all its life forms
- it is not important how he did this, what is important is that he did
- God gave us responsibility of dominion over other life forms
- humans should maintain a close relationship with their creator (God)
6
Q
Strengths of the literal interpretation of the religious explanation
A
- clear and unambiguous (takes away any need for guessing or differing
interpretations) - gives answers to the meaning and purpose of human life (God created us specially, we have a role and purpose)
7
Q
Weaknesses of the literal interpretation of the religious explanation
A
- genesis 1 and 2 tell very different stories, you cannot accept both as being the absolute truth (one must be wrong)
- ignores scientific evidence for the origins of life
- not open to debate with anyone who doesn’t accept the bible as true (no leeway)
8
Q
Teleological argument
A
- put forward by the English theologian William Paley
- based on the observation that living things in the universe are incredibly complex, showing evidence of design
- it is silly to believe that something as complicated as the human eye or the distance from the sun to Earth came about by accident
- we must therefore conclude that there is a designing force behind nature
- Paley believed this force is what people call God
9
Q
Strengths of the teleological argument
A
- its logical and makes sense, the world is so orderly and fit for purpose surely this must be the work of an intelligent designer (God)
10
Q
Critiques of the teleological argument
A
- the world is not perfect, it has as much chaos and suffering as beauty, why would an intelligent designer create so much mayhem
- nature could be providing the design itself, no need for God (evolution)
- the argument points towards a designer, not necessarily a Christian God
11
Q
Scientific explanation
A
- scientists believe that life on Earth has changed over time
- this is the process referred to as evolution
12
Q
Theory of evolution by natural selection
A
- the theory was put forward by Charles Darwin
- based on the idea that all species on Earth evolved from simple life forms that existed millions of years ago
- relies on their being genetic variation in a population which affects the physical characteristics of an organism
- individuals with characteristics best suited to their environment are more likely to survive
- these individuals are more likely to reproduce and pass their genes on to their offspring
- as a consequence those individuals most suited to their environment survive, and given enough time the species will gradually evolve
- supported by evidence of fossil records and vestigial features
13
Q
Fossil records
A
- used as evidence for evolution
- fossils are the preserved remains of living organisms found in rocks
- the fossilised remains of organisms that no longer exist today show us that life on
Earth has been changing for a very long time
14
Q
Vestigial features
A
- used as evidence for evolution
- there are structure that have no apparent function and appear to be left over parts form a past ancestor
- an example is the human appendix, it has no function now but is thought to have had a function for our past ancestors
15
Q
Strengths of scientific explanation
A
- meticulously researched
- supported by recent developments in many different scientific disciplines
- provides an explanation for biodiversity and the similarities between species
