Which of the following is a shared trait of mitochondrial AND Y chromosome DNA that makes both ideal for reconstructing the history of human migration?

This DNA is only inherited from the mother.

No genetic recombination occurs for this type of DNA.

This DNA is incredibly small and circular, sized at only ~17,000 bp.

There are many copies of this DNA in each cell.

Which of the following best describes the half life of uranium-235?

Starting at 100%, after 704 million years 50% will be left, after another 704 million years nothing will be left.

Starting at 100%, after 704 million years 50% will be left, after another 704 million years 25% would be left.

Starting at 100%, after 5730 years 50% will be left, after another 5730 years nothing will be left.

Starting at 100%, after 5730 years 50% will be left, after another 5730 years 25% would be left.

You travel back in time to the Earth exactly 1.5 billion years ago, which of the following are you LEAST likely to find?

Single celled prokaryotes.

Single celled eukaryotes.

Multicellular eukaryotes.

Sponge-like animals.

Regarding natural selection in modern humans; it...

has not occurred as there has not been enough time since our separation from the human common ancestor.

will no longer occur due to our medical advancements.

can be seen in the adaption of short stocky bodies of indigenous peoples in cold regions.

means there are currently multiple species of human.

When using fossil evidence to produce a 'total evidence' phylogenetic tree, you would most commonly place the fossils....

...on a molecular base tree using molecular evidence.

...on a morphological base tree using molecular evidence.

...on a molecular base tree using morphological evidence.

...on a morphological base tree using morphological evidence.

Analyse the phylogenetic tree above carefully. Based on it, we can conclude:

Image failed to load

Species C is the least advanced.

That E and F are the most advanced species.

There is a closer evolutionary relationship between C and D than C and E.

That C and F are more evolutionarily related than C and B.

This would be an example of:

Which of the following is/are LEAST useful when constructing a phylogenetic analysis of organisms?

Synapomorphies.

Analogous traits.

Homologous traits.

Parsimony.

The sperm and egg of two animals do not carry the appropriate molecular receptors to allow fertilisation.

Mechanical incompatibility.

Genetic incompatibility.

Gametic isolation.

Behavioural isolation.

The convergent evolution of analogous physical traits in two species is the major limitation of which of the following species concepts?

Biological species concept

Ecological species concept

Morphospecies concept

Epigenetic species concept
