New Evidence for Evolution Flashcards
What are the limitations of using fossils to show evolutionary relationships?
Fossils only form from organisms with stiff structures. So if their is a weaker part of the body it more likely to become decomposed
Limitation of DNA profiling
DNA starts to degrade immediate after death
How is evidence validated
Dedicated scientific journals
Peer review
Scientific conferences
What are dedicated scientific journals
any research carried out must be published in at least one journal so it can be read by other scinetists
What is peer review
the editor of the journal sends the paper to 2 or 3 scientists in the same area of work
Suggest how DNA analysis could give further evidence
similarity of DNA indicates closeness of relationship
because genes are sections of DNA
genes are the codes for protein
