human evolution-8

Question 1

what methods can be used to assess human evolution?

Answer 1

• archaeology
• anthropology
• specific genes
• linguistics
• molecular groups
• interactions with other species

Question 2

archaeology. example?

Answer 2

otzi iceman found in the alps. isotope composition of tooth enamel shows where he grew up

Question 3

anthropology. example?

Answer 3

brain size of hominids informs number of social interactions and problem solving

Question 4

specific genes. example?

Answer 4

olfactory receptors human vs chimp

humans have more pseudogenes and fewer actually active genes

Question 5

linguistics. example?

Answer 5

diversification of language clades (comparative studies)

Question 6

molecular group. example?

Answer 6

markers such as blood groups

Question 7

interactions with other species. example?

Answer 7

bacteria can be used as a marker of migrations

Question 8

what did the study of the 3 neanderthal female bones how?

Answer 8

compared their genomes to present humans.
europeans and asians share dna where as africans dont
so hybridisation happened when humans and neanderthals were together

Question 9

what did the study of denisovans bone show?

Answer 9

genome similar to us so apparent hybridisation

also their population was small because from the bone there was little genetic variation and had homozygosity at loci

Question 10

what is the y chromosome type associated with?

Answer 10

with the geographic location

Question 11

what is equal female and male norse contributions to the gene pools of shetland and orkney consistent with?

Answer 11

vikings migrating in family groups
