What is Evolution?
Slow gradual change of populations over time ****
100
What drives Natural Selection
Enviormental Pressures
100
Why do geologist lick rocks?
To see if its a fossilized bone or if its a normal rock
100
What is comparative Anatomy?
*****
shape/appearance morphology of organisms ancestry and relatedness
100
What is biochemisrty
Comparison of proteins & DNA of organisms
- determines common ancestry
200
Evolution is caused by?
Natural Selection
200
What is the famous saying related to Natural selection
"Survival of the Fittest" *****
- Those with traits best adapted to their environment are able to live long enough to reproduce and pass down those traits.
200
What is a fossil?
*****
Preserved remains of dead/extinct organisms
200
What is a homologous structure and provide an example
*****
Structures with different external appearances and function but similar internal shape (similar to relatedness)
-Human arm, whale flipper, bird wing, bat wing, cat leg
200
True or False: All organisms share the same genetic code to build proteins
True!
All organisms share the same genetic code to build proteins. Similar Amino Acid sequences of proteins show similar DNA and close relatedness
- ancient common ancestor
300
Who was Charles Darwin? List 3 things that made him significant.
*****
Collected evidence to support his ideas of evolution; evolution caused by natural selection.
- HMS Beagle to Galapagos islands
- Darwin's finches & their beak variety (due to food availability)
- Evidence of evolution from ancestral population
300
What is artificial Selection
"Selective breeding" ****
HUmans choose traits to be passed on to the next generations- dog breeds
300
What type of rock are fossils most commonly found?
****
Sedimentary rock
300
What are analogous structures and provide 2 examples
Similar structures due to adaptations caused by similar environments
NOT RELATEDNESS
Sharks & Dolphins
300
True or False: The process of burning sugar to make energy is specific to humans only.
False
All organisms use the same process of burning sugar to make energy
400
What do mutations have to do with evolution
Random changes in DNA *****
- can create new traits
- Selected for or against by environment (natural selection)
400
How does artificial selection support evolution?
****
Humans can create evolution by selecting characteristics for organisms- NOT natural selection
400
What species walk on four legs?
Salamander, turtle, leopard
3- species
400
What is a vestigial structure and provide 3 examples
No longer functions or preforms the same job as it did for ancestors
- Appendix, wisdom teeth, body hair, goosebumps
400
What is the difference between convergent and divergent evolution?
Convergent- Separate unrelated species developed the same adaptation based on similar environments
Divergent- One species (common ancestor) divides into many individual species, all related back to the common ancestor
500
What is a Cladogram?
Diagram that shows evolutionary relationships
500
What are the 4 concepts of Natural Selection?
****
1. Variation: differences of traits in population
2. Inheritance: traits passed down to offspring
3. Overproduction: struggle to survive or competition
4. Differential Survival and reproduction: Those with the best traits survive so best traits are passed down
500
How do fossils support evolution? Provide 3 ways
*****
- Shows record of gradual/progressive change in a group
___example: Trilobites
- can reveal transitions
____ example: Tiktaalik, archaeopteryx
- Can show when traits appeared
500
What are three key points of embryology? - What is it - What did we talk about?
******
What is it? Comparing shapes of embryos/development
- All vertebrates have similar early embryonic development
- All have tails and gills
- Suggests common ancestry of all vertebrates
