Question 1
8 out of 8 points
Please match the following definitions to their appropriate terms. Note that there
are more terms than definitions.
Question Selected Match
Early model of modern human origins that claimed all fossil J.
hominins were part of one continuously evolving lineage. Single-species
hypothesis
This mostly-complete fossil of a young Homo erectus from E.
East Africa provides evidence that this species grew up Turkana Boy
relatively fast.
This is a form of non-random mating in which individuals H.
marry others with similar traits (e.g. tall people in the US Positive
marrying other tall people). assortative
mating
This type of mutation in a DNA sequence does NOT result in G.
a change in the amino acid produced by that sequence. Synonymous
mutation
All Answer Choices
A.
Stabilizing selection
B.
Non-synonymous
mutation
C.
Endogamy
D.
Negative assortative
mating
, E.
Turkana Boy
F.
Multiregional model
G.
Synonymous mutation
H.
Positive assortative
mating
I.
Dmanisi
J.
Single-species
hypothesis
Question 2
Needs Grading
Approximately when did our human ancestors start to lose their body hair? When
did they start to wear clothing? What evidence have researchers used to study
each of these? (Note: make sure you state two specific examples of evidence --
one for hair loss and one for the adoption of clothing.)
Selected Our human ancestors started to lose their body hair about 3 million
Answer: years ago. We know this because it is about the time the head louse
and the pubic louse diverged into seperate species. This is due to
genetic drift.
They started to wear clothing 170,000 years ago. Researchers used
molecular clock dating to see when the clothing louse species diverged
from head lice. Clothing louse would need clothing to evolve, so this is
about the time humans began wearing it.
Question 3
2 out of 2 points
Which of the following are true about "Mitochondrial Eve"
Selected "Mitochondrial Eve" refers to most recent common ancestor of all
Answers: modern mtDNA lineages that have been sequenced.
"Mitochondrial Eve" was likely one of many females living in her
population at the time.
Answers: "Mitochondrial Eve" refers to most recent common ancestor of all
modern mtDNA lineages that have been sequenced.
"Mitochondrial Eve" was likely one of many females living in her
population at the time.
"Mitochondrial Eve" probably lived in Asia.
"Mitochondrial Eve" was the first Homo sapiens fossil that preserved
ancient DNA.
