Evidence of Evolution
When comparing bone structures of organisms, there are not any structural similarities but their function is the same. What form of comparative anatomy is this?
Analogous structures.
Over time, hominid jaw size has...
decreased.
Natural selection is also known as what?
Survival of the fittest.
Gene flow is a different term than genetic drift, what is the definition of gene flow?
Gene flow is when a member of a population moves to a separate population and mates, this increases genetic variation and diversity.
NO! We just have the same common ancestor.
If two animals have very similar amino acid sequences, they are likely closely related. This is an example of what type of evidence of evolution?
Comparative Biochemistry
Over time, hominid skull size has...
increased in size.
The theory of evolution is a theory because it explains what?
HOW evolution has happened.
In your own words, what is the bottleneck effect?
Miss Ro's Descretion.
What does it mean to be a heterotroph?
A heterotroph is an organism that cannot make its own energy. It needs to get nutrients from other things.
Honey possums lick nectar from flowers using a long tongue made of soft muscle. Butterflies lick nectar from flowers using a long tongue made of chitin, a hard protein.
What type of SPECIFIC evolutionary evidence is presented in this scenario?
Analogous Structure
What is the name of humans' ability to walk upright on 2 feet?
Darwin is the founder of natural selection, but Alfred Wallace was also very close to founding this theory himself. What ship was Darwin traveling on and what island did he venture to?
HMS Beagle and the Galapagos
Describe one example of non random mating.
Peacocks, tropical bird dances, males fighting for female 'territory'
What is the endosymbiotic theory
Mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria that were ingested by a large anaerobic bacteria.
Members of the camel family come from a common ancestor but live on different continents, this is an example of which form of evidence of evolution?
Biogeography
Humans developed the ability to walk upright due to their need to do what?
Use tools.
What evidence of evolution did Darwin use to make his theories of evolution?
Comparative Anatomy, maybe biogeography.
What is it called when over many generations the median (middle) genes are chosen over the more extreme genes/phenotypes.
Stabilizing selection
What inorganic compound that started as ammonia, hydrogen and water, became the compound that all life from Earth came from? (Think proteins!)
amino acids
What is the name of the evidence of evolution that looks at pre-developed animals and makes comparisons on their similarities and differences?
Comparative Embryology
What is a vestigial structure AND an example of it in humans?
A vestigial structure is a structure that has lost its use over time due to evolution.
Give one example of artificial selection.
Miss Ro's discretion
What is it called when the extreme phenotypes are chosen over the intermediate ones?
Disruptive or diversifying selection.
What did Miller and Urey do?
The experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. (They tried to explain the origin of life on earth)
