Document Summary

We can than go further trying to uncover the underlying cause with more why questions. Is a complex hypothesis that rests on a series of assumptions. Evolutionary biology mandate: pose ultimate questions and evaluate their plausibility. Tells a clear unambiguous story at the level of genes and than drawn to an ultimate explanation. molecules. Natural selection takes time and it does not produce perfection. Maladaptive traits are likely to be prominent in a changing environment where new. Ex humans attraction to fatty/ sweet foods is now maladaptive because those foods used. Maladaptive traits can be maintained by tradeoffs and constraints. A feature can have more than one function ecological challenges change the fitness consequences of pre existing characteristics. to be rare but now they are common. Natural selection does not act directly on trains or genes in isolation. Individual organisms its effect on fitness.
