- transitional feature
- overtime do species develop more complex traits due to evolution
- heterozygous advantage
- what is the only mechanism that by itself can produce adaptation
- Morphospecies concept
- a groups that can be described as different based on consistent morphological differences
different appearances often evolve when populations undergo divergence
the morphological forms will persist only if reproductive isolation is achieved.
Evolutionary independence is assumed but not known It's easy to apply but very subjective because the species is what the "expert" says. It's hard to use on unicellular organisms because they have no distinguishable features, and evolutionary indepencdence is often difficult to assess.
- b no because complex traits are routinely lost and simplified over time as well as more complex ones created.
- c a trait in a fossil species that is intermediate between those of younger and older species.
- d a type of selection where organisms that are heterozygous have an advantage over homozygous this allows for genetic variation to remain in a population.
- e natural selection
5 Multiple choice questions
- it decreases it
- the concept that all living organisms conform to a norm and that variation is abnormal
- infering trees based on similarity in charactaristics
- The fact is that life changes over time The theory regards the mechanisms that enable change over time
- pursuit of knowledge for the sake of knowledge using science to explain and predict. In part it helps to further applied science
5 True/False questions
Allopatric speciation → "in same place" geographically yet barriers to gene flow are established. isolation may occur because of reproductive cycle times like flowers releasing pollen early can lead to speciation.
phenetic approach → infering trees based on similarity in charactaristics
Linnaeus → your contribution to the gene pool for future generations the higher your ability to reproduce and survive the higher your fitness.
example of directional selection → large cliff swallows survived because they had more fat stores in a cold snap so the large allele became dominant for survival. might not be fixed though
Out group → opposite in common characteristics to other animals in order to compare to
