When determining molecular homology, the evolutionary history of a species can be seen in its DNA sequences. This means that

the more closely related two species are the more similar the DNA sequences

speciation occurs when DNA becomes more similar

homology is the study of same DNA sequences in all living things

the order of evolution happens in a predetermined sequence

1

The main reason for rapid changes in nuclear DNA gene sequences of a population is:

genetic drift

interbreeding with other populations

lack of gene flow

different selection pressures acting on favourable traits

1

Phylogenetic trees and cladograms help show relationships between different organisms. The difference between them is that

cladograms always represent closely related species on the same line

phylogenetic trees have branches that represent time and amount of change

phylogenetic trees have branches of equal distance for closely related species

cladograms always have humans at the top

1

When considering the phylogenetic tree above, what can be determined?

The black bear and giant panda would be able to interbreed

The walrus and the giant panda have a recent common ancestor at 4mya

All branches have a common ancestor 10mya

The island fox became extinct 4mya

1

The cladogram above shows the evolutionary relationship of 5 species.
With respect to the diagram above, it is reasonable to say that:

living fish have all the features of the other organisms

all species have 2 arms and 2 legs

mammals, birds and living reptiles have warm blood

birds, mammals and living reptiles have eggs that can be laid in air

1

With respect to the diagram above, it is reasonable to say that:

crocodiles and birds are more closely related than primates and rabbits

all species with a bony skeleton have four limbs

amphibians do not have any features that are shared with other groups

vertebrae are an ancestral trait common to all groups shown.

1

From the information in the diagram above, it can be said that:

racoons are more closely related to weasels than bears

canids and civets diverged from a common ancestor at the same time.

bears and seals have a common ancestor

fur seals and sea lion arose from walruses

1

The most recent divergence of two bat species is the

slit-faced and sheath-tailed bats

evening and long-fingered bats

sucker-footed and New Zealand short-tailed bats

smoky and fishing bats

1

Analysis of the evolutionary tree above shows that

lorises is the oldest group in the evolutionary tree

gibbons and old world monkeys are unrelated

chimps and humans are more closely related than gorillas and chimps

the most recent group to evolve separately is humans
