Question 1

2/3 ways brain has changed in evolution

Answer 1

• gained regions for speech
• changes in occipital and anatomical portions of brain
• changes can lead to new functional fields (speech) or enhance previously existing functions (texting thumbs)

Question 2

Answer 2

mom + and baby - = no problem

mom - and baby + = problem

Question 3

What molecule creates the ABO system?

Answer 3

H anitgen

Question 4

Which factor increases variation but does not alter allele frequency?

Answer 4

genetic recombination

Question 5

2 factors that help maintain the center of gravity in humans?

Answer 5

• S shape spine

- femur is pointed inward (increased valvus angle)

Question 6

How has the brain developed to give more capacity

Answer 6

-creation of wrings and convoluted lines in sulcus, increases surface area without increasing size

Question 7

2 elements that affected reproductive timing in Neandertals

Answer 7

1. fast brain size increase in infants

2. If mom is done growing and out of personal development then food intake just goes to baby

Question 8

Advantages of having 2 male marmosets?

Answer 8

-males watch babies so mom can go hunt and eat without baby and bring back nutrients for both

Question 9

How large is homoerectus brain size

Answer 9

80% the size of current human brain size

Question 10

What prevents baby’s from choking?

Answer 10

-epiglottis touches soft pallet, which cuts off and prevents choking

Question 11

What can type O blood do that BO cant?

Answer 11

O= universal donor

BO can’t make B antigents because it would attack its self but O can
