Evolutionary Biology

Sur cette roue (21 options)

• Shared ancestry among vertebrates means that zebra fish and humans exhibits similar developmental stages.
• Mutations, natural selection
• Evolutionary arms race
• assortative mating and mate choice
• group of individuals belonging to the same species
• group of individuals which can interbreed and produce viable offspring (following the principle of Biological Species Concept) Not evolution.
• causes of evolution
• Increased mortality • Reduced reproductive success
• Reduced mortality • Increased reproductive success
• morphologically similar species
• minor evolutionary changes of populations viewed over a few generations 
• major evolutionary events viewed over long period, such as formation of new species
• Four aspects of the natural world which are important mechanism of evolution by natural selection:
• Traits which improve an individuals survival and reproductive success are passed from generation to generation.
• Differences among individuals.
• The reproductive ability of each species has the potential to cause its population to geometrically increase over time.
• Life strategies aims to improve chances of passing genetic material to the next generation.
• produces all offspring within a single reproductive event
• organisms which reproduce in successive years or breeding seasons
• those with distinct breeding seasons
• those that reproduce repeatedly and at any time of the year
