structures
Homologous Structure: give an example
Same structure different function
Plate tectonics supports the theory of:
continental drift
Define: Adaptation: give an example:
A: a trait that helps an organism survive and reproduce-pocket mice color
Group of organisms that can mate and produce fertile offspring
species
To prove that evolution occurred using rock formation
fossils
Vestigial Structures: give an example
Once used no longer used (whale femur)
Divergent creates
rifts
Charles Darwin formulated
the Theory:
Theory of Evolution by Natural Selection
Changes in an organism's
DNA is called:
mutation
Using the embryo of a human, rabbit and fish to show they shared a common ancestor is called:
embryology- shows evolutionary relationships/common ancestry with vertebrae animals
Define: Analogous structures: give an example
Same function different strcuture (bird wing bug wing)
Restrict movement across the Malay Archipelago was caused by :
sea level rise
Describe Darwin's theory of evolution:
organisms that are best adapted to the environment survive
Describe each type of Isolation:
Behavioral: different mating rituals
Geographic: separated by geographic features
Temporal: reproduce at different times
Less differences in means
What is embryology? and how is used to show evidence of evolution
convergent creats
moutains
what is natural selection?
nature "selecting" the best "fit" trait
There are short neck and long neck giraffes, there are dark moths and light moths....
This shows what in the populations
variation
How can we use biogeography as an example of evolution
shows the distribution of organisms in similar areas
Having homologous structures could show what?
COMMON ANCESTROY
When the ocean floor sinks beneath a deep-ocean trench and back into the mantle
subduction
Speciation occurred with the finches on the Galapagos Islands due to 3 things:
1-natural selection
2- speciation
3- isolation on different islands
Where is new crust made?
The ocean
What are pieces of evidence for evolution
1. Fossils. 2. Biogeography 3. Embryology 4. Structures 5. DNA
