What is macroevolution

What is Microevolution
natural selection/adaptation
Know each of the 4 pillars of intelligent design
- Natural structures will be found that contain many
parts arranged in intricate patterns that perform a
specific function - Forms containing large amount of novel information
will appear in the fossil record suddenly and without
similar precursors - Convergences will occur routinely. That is, genes and
other functional parts will be re-used in different and
unrelated organisms - Much “junk DNA” will turn out to perform valuable
functions
Know each of the 3 of Selection Process
Directional selection- a shift towards a trait
Stabilizing selection- intermediate/average traits are found
Disruptive selection- favors both sides of rarity
