• Macro-evolution: A change above species level which leads to more highly developed groups of organisms over time.

• Lineage: An evolutionary line.

• Anagenesis: Is a change within a lineage with no branching. A species gradually changes until it may be regarded as a new species.

• Cladogenesis/divergent evolution: Is the evolutionary change in which the ancestral species lineages (branches) split into two or more species. This is a very common mode of evolution.
• Ecological niches: The roles and spaces for organisms to occupy in the ecosystem

• Adaptive radiation: The rapid formation (in geological time) of many new species from a single ancestor. This occurs when there are new ecological niches to fill. An example would be the evolution of mammals.

• Simplest organism: Simple organisms such as algae, was the simplest organism to have appeared first. It survived for hundreds of millions of years before the appearance of more advanced forms.

• Increase in diversity: Fossils show the increase in the diversity of families of species over time.

• Invertebrates:

• Vertebrates:

• Animal and plant evolutionary divergence:

• Transitional fossils:

• Archaeopteryx:

•

• Background extinctions:
