Natural selection
- Evolutionary adaptation
- Speciation
Coelacanth
nautilus
human, cat, bat, whole
Homologous structure
they are body parts of species
that have similar feature, indicating
a common ancestor or same
develop mental origin bat
Analogougs structure
butterfly
bird
have similar functions but
with dissimilar evolutionary origins.

Reproductive Isolation
1. Prezygotic barrier / Premating
Habitat isolation
-
- behavioral isolation
- Seasonal isolation
- Mechanical isolation
gametic isolation

Postzygotic barrier
-Requced hybrid viability
-Reduced hybrid fertility
-Hybrid breakdown
