Q6: A
Q7:D
Q8:C
Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.
Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.
Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.
Political science is the study of theory and practice of governance.
The theory of Natural Selection was accepted after it got consensus from
scientists.
<h3>What is natural selection?</h3>
The theory of Natural selection defines the process in which individuals who adapts to their environment survives and reproduce more offspring.
- This theory was proposed by a scientist called Charles Darwin and Alfred Russel Wallace who also had the idea of evolution.
- This two scientist work together to publish a book on new evolutionary theory titled On the Origin of Species (1859). This is because they believed evolution occur through natural selection.
In this theory, organisms produce offspring but not all offspring survive this because they all struggle to live.
survival is based on survival of the fittest. some of those who survive can reproduce their kind while some do not grow to maturity and are loss.
Therefore, The theory of Natural Selection was accepted after it got consensus from scientists.

Answer:
The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.
It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.
The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.
The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.
Consequently, the genetic diversity would also decrease.
