Creationism and Darwinsim Flashcards
what are the two ideas?
you can have decent with modification without natural selection
ID creationism
not against evolution, but supernatural being explains life
Not science
no one saw it, can’t be tested but
if descent with modification is true there should be:
1. species living now will be different to species in past
2. only simple organisms in the old state
3. connecting forms between major taxa
4. should not be fossils out of place
evolution is just a theory
is a well-substantiated explanation eg gravity
gaps in fossil record
- taxa suddenly formed
- but over time more fossils formed eg feathered dinosaurs that fill gaps
natural selection is chance
mutation is chance, NS is not, picked out by best adapted from pool
method of knowing what is science
- authority- someone tells you
- revelation- unquestionable source, you have to really believe this source
- logic- can be factually wrong
how do species change?
human population unchecked will grow and outgrow resources, weak will die
natural selection
- variation in traits
- variation is partly heritable
- variation in a trait is the same as variation that is relative in number of offspring
what darwin didn’t know
- traits are heritable but how
- pangenesis - gemmules transferred from each organ to reproductive organs
- DNA
