Fossils or organisms that demonstrate traits between an ancestral group and its descendants
Intrusive species
Transitional species
Index fossil
Trace fossil
Which evidence show patterns of change in organisms from early life to modern life?
homologous structures
transitional fossils
vestigial structures
proteins
Which species' DNA is most similar to the DNA of the toothed whale?
Mutations are important because they produce:
death of the organism in which they develop.
new traits that help natural selection occur.
benefits for the individual, not for the population.
Hardey-Weinberg equilibrium within a population.
Fossils form when dead organisms are:
completely decomposed
rapidly buried under sediments
eaten by scavengers
reincarnated
When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?
Selective breeding
Natural Selection
Cloning
Evolution of all species
The whale shares a common ancestor with a:
Sturgeon fish
Pot belly pig
Hippopottamus
Camel
Define pentadactyl.

Four digits
Both 1 and 2
Two digits
Cichlid fishes in lakes of the East African Rift. The lakes in this area are believed to support and sustain about 2,000 different species of these fish, each with different ecological and morphological characteristics such as body size. These lakes form a fragmented landscape that bio-geographically isolates the different species of cichlid fish from one another, allowing them, and many of the organisms they live with, to evolve separately.
Phyletic Speciation
Adaptive Radiation
Convergent Evoltion
Divergent Evoltuion
Co-evolution
Process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches
Adaptive Radiation
Geographical Isolation
Diversification through domination
Recessive Isolation

Elk: ARG - PRO - TYR - ARG
Dog & Rabbit
Rabbit & Elk
Dog & Elk
What are tusks?
Long teeth that help elephants dig and fight
Long teeth that help elephants eat other animals
Long teeth that don't help elephants at all
What is tusklessness?
When an elephant has its tusks taken away
When an elephant is born without tusks
When an elephant has tusks
When an elephant dies
What does survival of the fittest mean?
Animals with the most muscle live
Animals that live in groups live
Animals that are fit for their environment are more likely to survive and reproduce
Animals that workout are more likely to survive and reproduce
Why did the percentage of elephants that were tuskless increase over time?
More elephants decided to be tuskless
The tuskless elephants were able to reproduce and pass the trait down
More elephants had their tusks fall off
The tuskless elephants all died
Why is being tuskless an advantage?
Elephants don't need their tusks so it doesn't matter
There is no advantage to being tuskless
Elephants don't have to worry about brushing their teeth
Elephants won't be targeted by human poachers because they don't have ivory (tusks)
Why is being tuskless a disadvantage?
Elephants don't need their tusks so there is no disadvantage
Elephants won't be able to protect themselves without them
Elephants won't look cool without tusks
Elephants have to clean their tusks
Why did the percentage of elephants that were tuskless increase over time during the civil war in Uganda?
More elephants decided to remove their own tusks
The tuskless elephants were able to reproduce and pass the trait down
More elephants had their tusks fall off as they aged
The tuskless elephants all died at this time
Where else have high levels of tusklessness been observed?
Gorilla habitats
Bird sanctuaries
Lion populations
Other heavily poached areas
What is the BEST explanation for why males are not born without tusks?
Tusks are necessary for battling with other males in African Elephants.
The tuskless gene is a dominant gene located on the X-chromosome. The gene is lethal if an organism only gets one copy as males do.
The tuskless gene is only expressed in the presence of estrogen.
They have adapted to producing tusks even though they don't have the gene.
