The Most Recent Common Ancestor (MRCA) is an individual who donated DNA to every single living person, meaning we are all related to each other through him/her. Which statement best describes the human MRCA based on mitochondrial evidence? O The very first member of our species O A woman who lived in Siberia 40-50,000 years ago This person was the only human alive at some point O A woman who lived in Africa 200,000 to 300,000 years ago

An allele that causes an altered form of hemoglobin occurs in all human populations. However in populations where malaria is a threat there is a relatively higher percentage of individuals with the allele. Individuals who have one allele for this condition have an increased resistance to malaria. Individuals with two alleles for this condition have significant medical problems and die young. This allele has been found in high numbers in certain populations in West Africa, Southeast Asia and Greece. What process of evolution likely led to the appearance of this allele? A-mutation B-genetic drift C-natural selection D-gene flow   Refer to the previous example (#2): What process of evolution likely led to this allele being in higher numbers in some populations? A-mutation B-natural selection C-genetic drift D-gene flow

How do we know mitochondrial Eve is every human's ancestor? because only males pass on mitochondrial genes global comparison of nuclear DNA global comparison of human mitochondrial and nuclear sequences comparison of African mitochondrial DNA from the past from fossil remains found in East Africa around 50,000 years ago 00

Which phenomenon describes individuals that do not share a common ancestor? O Convergent Evolution O Divergent Evolution Homologous Structures O Adaptation

The neutral theory of evolution proposed that most genetic mutations are functionally neutral or nearly neutral. Neutral mutations would be fixed in a population by: O the invariance of DNA O random genetic drift O balancing selection natural selection asexual reproduction

Anthropology

Why do you think such a small portion of Neandertal or Denisovan DNA exists in the gene pool of modern humans?  Why not more?

Mutation is the raw material for evolution O True O False
