Evidence of ev
Homologous Structure: give an example
Same structure different function
Define: Adaptation: give an example
a trait that helps an organism survive and reproduce-pocket mice color
Group of organisms that can mate and produce fertile offspring
species
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
Vestigial Structures: give an example
Once used no longer used (whale femur)
Charles Darwin formulated
the Theory:
Theory of Evolution by Natural Selection
What is behavioral isolation
different mating rituals
Less differences in means
CLOSER RELATION
What is embryology? and how is used to show evidence of evolution
the study of development in the womb, similar development could mean common ancestor
Describe Darwin's theory of evolution:
organisms that are best adapted to the environment survive
What is geographical isolation
separated by geographic features
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
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
What is adapting?
Change in allele frequency in a population overtime but keeping the same species
To prove that evolution occurred using rock formation
fossils
Speciation occurred with the finches on the Galapagos Islands due to 2 things:
natural selection
isolation on different islands
What is temporal isolation
Temporal: reproduce at different times
List the 5 evidences for evolution
1. Fossils. 2. Biogeography 3. Embryology 4. Structures 5. DNA
