Explain what is meant by Cultural Evolution (with examples) and discuss why we say it occurs by Lamarckian methods? What is the significance of Lamarckian methods for Cultural Evolution?

Discuss the main application of the Hardy–Weinberg principle in evolutionary biology.

When several possible phylogenetic trees can be produced from a data set, the most parsimonious tree: O is the one that shows the smallest number of synapomorphies. O is the one that shows the largest number of nodes. O is the one that shows the largest number of analogous characteristics. O is the one that shows the smallest number of evolutionary changes. O is the one that shows the smallest number of branches.

The molecular clock is a tool that can be used to; Determine the age of a fossil Determine if a population is undergoing sexual selection Determine if a population is in hardy weinberg equilibrium Determine how long ago two different species diverged from each other

A scientist is studying two different species of fish. The table below shows various observa- tions that the scientist could have seen in the two different species of fish. Observation Number A B с 1 D 2 3 4 observation 1 observation 2 observation 3 Genetic Similarity observation 4 high low low high Function of Structure different same Which observation number would best support the claim that the two species have structural similarities, specifically as a result of convergent evolution? different same Form of Structure same different same different

The second step of classification is using homologous traits to determine the relationships between organisms. Based on the traits you identified in Exercise 3, it should now be possible to group some of the objects together. Objects that share a derived trait are related to one another, and they should be grouped together. Objects that share multiple shared derived traits are closely related, and they should be subgroups within larger related groups.Describe the groups in which you would place these objects, starting with groups with the largest number of objects and ending with the group with the smallest number of objects.

Directions: Examine the chart below: 0 means the trait is absent, 1 means the trait is present. Notice that a couple of things are different from the previous charts. Firstly, the derived traits and species name have switched axis. Secondly, you will see that in this chart there are derived traits that have evolved independently in different organisms. Use the principle of maximum parsimony to make a draft of the cladogram. The theory of maximum parsimony states that the simplest explanation consistent with the data should be examined first. The most parsimonious trees require the fewest evolutionary events. Construct your own cladogram using the information from the chart as a guide.
