Hypothesis-DrivenScience
|
–Make observations–Determinea question–Formulatea testable hypothesis–Make a prediction based on the hypothesis–Conductan experiment–Acceptor Reject Hypothesis–Reviseor update hypothesis as necessary
|
|
|
ScientificMethod
|
•A basic guideline for how to use observations to draw conclusions
|
|
|
Hypothesisvs. Theory
|
•A hypothesis can be accepted or rejected•A theory is much broader in scope and supported by numerous lines of evidence,e.g. the theory of natural selection
|
|
|

|
|
Domains |
•Broadestlevel of organismal organization

Evolution |
•Unifyingprinciple of biology
•Descentwith modification –Changein genes/gene frequencies over time –Achievedby natural selection |
|
|
Natural Selection |
•Moreindividuals are born than can survive
•In apopulation, there is variationamong individuals in a number of traits •Someof this variation is heritable,passed from parent to offspring |
|
|
Adaptation |
•Anadaptation is a variant of a trait that has a selective advantage
•Individualspossessing the adaptation have greater fitness (reproductive success) –In ElNiño years, having a beak with smaller depth is advantageous |
