|
What is the inheritance of acquired characteristics?
|
the effect of the envorionment somehow could be inherited by their offspring
|
|
|
What did Lamark suggest?
|
Giraffe example: the short neck giraffes changed because they needed to reach higher trees. CHANGE BY STIMULUS
|
|
|
What are the best arguments for evolution?
|
Branching organization of life, homology, vestigial structures and imperfections, embryonic history, biogeography
|
|
|
What is Morphology?
|
the relationship between the form and the function of an organism seen in an adaptive and evolutionary context.
|
|
|
What is the branching organization of life in an evolutionary context?
|
obvious bodily features of different animals being similar.
Monkey in relation to a human |
|
|
What is Homology in an evolutionary context?
|
Organs with different functions are built with the same basic structures. proving signs of evolution
bird wing bones in comparison to human arm bones |
|
|
What are vestigial structures and imperfections in an evolutionary context?
|
showing parts of the body that have no use, but suggest there was a use in previous times before the animal evolved to its current state
|
|
|
What is embryonic history in an evolutionary context?
|
embryos in early stages are all similar regarless of the species, showing signs of one common ancestor
|
|
|
What is biogeography in an evolutionary context?
|
the same animal but there are different look and shapes based on the area that it is in
|
|
|
What is Mendel's Attribution to series of Change?
|
genetic mutations occur when adaptation is forced upon the organism
|
|
|
What are the types of Modern Evolution?
|
Divergent Evolution, Adaptive radiation, speciation, and covergent evolution
|
|
|
What is Divergent evolution?
|
the idea of one common ancestor, but evolving differently depending on the environment
(Seals vs Wolves...Sea vs. Land) |
|
|
What is Adaptive Radiation?
|
an organism adapts to the environment it is in (the ones that do not adapt become extinct)
Short neck giraffe evolved to long neck in order to survive |
|
|
What is Speciation?
|
groups evolving away from each other to form different species, with the inablity to produce viable offspring
lions vs tigers, horses vs donkeys |
|
|
What is Convergent evolutions
|
2 different groups evolved to look similar due to the same environment
(sharks vs dolphins) |
|
|
What is a perched species?
|
a species that adpated to the environment so much, that any change will cause extinction
ex. Dinosaurs |
