Remember that evolution is defined as a change in the gene frequencies in a population over time.
survive to reproduce and proliferate the species
Speciation Macroevolution Adaptive radiation Divergent evolution Descent with modification
False, adaptationLike opposable Thumb

Two unrelated species evolve to have similar traits with similar functions (but different structures)

Organisms evolve from a common ancestor into different species

Sedimentary
Not “dinosaurs are stupid” or any similar choice
A. fish and humans B. snakes and chickens C. oak trees and elephants D. dogs and cats
Inheritance of acquired traits
Charles Darwin
Islands that were relatively close together were home to vastly different related organisms
◦ All birds, all finches, different beaks because why? Different niches, different food sources
Organisms are naturally selected because they are more fit to survive to reproduce and proliferate the species

A dominant lethal mutation would affect all offspring, limit reproduction and reduce the population
Mostly accepted, with some persecution

Embryos look similar arguing that they all came from a common ancestor Human embryos have pharyngeal slits
Fossil record Geographical distribution of living species
Homologous structures Similar embryology Antibiotic resistance
E (so choice C on your paper)
A. sexual reproduction is more hazardous than asexual reproduction, and only the fit survive.
B. asexual reproduction occurs only in one celled organisms.
C. sexual reproduction in more likely to produce a variety of offspring. ◦ Because of crossing over!

D. sexual reproduction is slower than asexual reproduction in producing offspring.
Domain, kingdom, phylum, class, order, family, genus, species, variety
(Take what you’ve heard of before and make it a sandwich- domain and variety are the bread!)
Animal and Vegetable
Felis concolor
Many organisms contain structures that have no function but that resemble functional structures of other organisms.
This suggests that the structures are inherited from a common ancestor.
◦ Humans have an appendix that seems to have no apparent function (although we may have needed it in the past to digest food)

What is the red arrow pointing to?
◦ Vestigial whale Pelvis and femur (legbone)
What does the evidence above suggest about the ancestors of whales?
◦ That they used to walk
How could vestigial structures like the whale pelvis and femur contribute to the theory of evolution?
◦ That all organisms come from a common ancestor

Just do as you did for Rat Island- use words like random mutation, survival of the fittest, reproduction, inheritance, speciation, etc.

• The Peppered Moth is an example of Natural Selection in action discovered by Haldane
• During the Industrial Revolution the trees on which the moth rested became soot-covered.
• This selected against the allele for pale color in the population (which were poorly camouflaged from predators) and selected for the dark color allele.

• The dog is another example of how selection can change the frequency of alleles in a population.
• Dogs have been artificially selected for certain characteristics for many years, and different breeds have different alleles. • All breeds of dog belong to the same species, Canis lupus (the wolf) so this is an example of microevolution as no new species has resulted.Dogs are all
domesticated wolves, just different varieties

39. The diagram below shows the most likely pattern of primate evolution. Strand A represents a sequence of DNA found in the chimp. Which of the other DNA sequences most likely represents the bonobo?
Strand C, only one DNA difference from strand A

40. What other aspect of organisms have we seen used to relatively place them [the organisms] on a cladogram?
Anatomy
41. Why are we able to agreeably compare organism phenotype and genotype on the same cladogram?
DNA codes for anatomy
42. Describe two differences among the following organisms’ cell structures.
Every kingdom except Animalia has cell walls
Protista and Plantae are the only kingdoms with chloroplasts
