Explanatory power
How well does it describe current observations?
Predictive Ability
How well does it predict future observations?

Irreducible Complexity
Nature is too complex to be created naturally, an intelligent being must have designed it
Probability
The odds of life evolving are too remote to have occurred by chance
Nested Hierarchy
Group organisms based on similar traits
Extinction
“If God was perfect at creating, then extinction wouldn’t happen”
Succession and Biogeography
Animals may be similar to those around them (marsupials), fossils look similar to extant species
Transitional Forms
Archopteryx, missing links
Shared Embryonic Features
Organismal development through stages show the tree of life
Homology
Common blueprints, one bone, two bones, many bones
Vestiges
Lost function/purpose but still there, appendix

DNA doesn’t solve it, how do we draw the line?

Tree thinking, first phylogeny, variation in repro success
Establishing the process
Natural selection
