NOVA EVOLUTION MISSION 5 AND 6 QUESTIONS AND
ANSWERS. Buy Quality Materials
a parasite
An organisism that can cause disease in its host, gains energy from its host and
requires a host to complete its life cycle.
host and parasite
The evolution of one greatly affects the evolution of the other.
HIV
The virus that causes AIDS.
E.euzeti and Red Snapper
In the host and fluke parasite phylogentic trees, these two organisms were an outgroup.
Human's Fluke and Green Turtle's Fluke
Their respective parasitic flukes are closely related on the phylogenetic tree.
Freshwater turtle fluke and Human Fluke
These two species of flukes must have switched hosts because the host tree does not
have the same pattern as the parasite tree.
Tiger Snake
Identity of the unknown snake that bit Tyler
Taipan Snake/Fierce Snake
#3 nucleotide is "A"/#8 nucleotide is "T"/gap between fangs/a double row of scales
under tail and would need to use antivenom B
Gorilla SIV
The ape virus most closely related to HIV-P that was first diagnosed in humans in 2009.
Rapid reproduction rate
Means more mutations and more opportunities for natural selection to affect populations
and a faster rate of evolutionary change .
Chimpanzees
closest living relatives to humans.
99.8%
The Approximate percentage of DNA humans share with chimpanzees.
h. erectus
1.89 mya to 143,000 years ago. First hominin species to spread out of Africa.
Australopithecus afarensis
Earliest hominin 3.85 to 2.95 mya.
homo sapiens
200,000 years ago to present
Homo neanderthalensis
Significant genetic evidence that this hominin population interbred with Homo sapiens.
No fossils of this groups have been found in Africa.
