NGSS.HS-LS4-1

Various structures in different species having the same appearance, structure or function but have evolved separately

• Analogous Stuctures
• Vestigial Structures
• Species
• Vestigial Structures

In what scenario could 1 species split into two

• A physical separation of a population

• 2 separate species need to breed to create a new species

• Hybrids can give birth to two different species

Why must populations be reproductively isolated in order for speciation to occur

• Different mutations arise in each population so they change differently over time forming different species

• They don't need to be reproductively isolated

• If the populations can breed they share mutations so do not evolve separately

• Vestigial Structures
