  • Speciation
    • Caused by isolation
      • Geographical Isolation
        • Groups of individuals in a species will no longer be able to reproduce. Different areas will have different selection pressures which leads to different mutations. Over time the two populations will become different species as the mutations build up.
      • Ecological isolation
        • Species occupy different areas of the ecosystem
      • Temporal isolation
        • species esixt in same area but reproduce at different times
      • Behavioural isolation
        • Species do not respond to each other's courtship rituals
      • Physical incompatibility
        • Species co-exist but physical reasons stop them from copulating
      • Hybrid inviability
        • Hybrids do not survive long enough to reproduce
      • Hybrid sterility
        • Hybrids are unable to reproduce
    • Process of forming new species
