• A)Features found in one clade are likely to be found in other clades inhabiting different environments.
• B)Features shared between two groups are likely to have been present in their common ancestor.
• C)Current trends of evolution will continue into the future.Complex models can be used to accurately predict future branching patterns and the nature of future adaptations.
