I find this very interesting and would love to research more about this. I wonder if they are in the works of developing new therapies and if so what are they?

I love this quote because of how true it is. Since everything in biology (and sciences) are always changing it makes sense that the only thing that makes sense is the light of evolution- which is talking about something that explains/shows all of these changes.

The opposable thumb is very useful in animals such as humans, monkeys, apes etc. so I am wondering if any other organisms will eventually evolve to develop the opposable thumb? For example, some cats are born with an extra digit so I am wondering if that could eventually be evolved to become opposable and increase their fitness.

What benefit does hairlessness have for us? Most other organisms have something covering the majority of their body such as hair, fur, feathers etc. so why did we evolve hairlessness?

I find this very interesting- I never thought of it this way that younger ages are more naturally selected to maintain health compared to older ages. I guess it all loops back to an individuals fitness and the naturally instinct to survive and reproduce in order to pass on your genes to future generations.

How often is this number changing/ updating? Will the number ever go down meaning a disease no longer exists or will it only increase?

Since we can all digest potatoes- does that mean this was seen as an adaptation that would increase an individuals fitness and was passed down from generation to generation?

To what extent can the bumps and shapes of the head be different from one another but still be related?

Very interesting! I would like to look more into this unknown population. What more do we know about them if anything? Could some of their genes be found in humans today that we are unaware of?

Where were these local populations that these groups interbred with? Are they still there today?

I feel as though sometimes we forget that we are also a species just like any other organism on this Earth and we are still discovering information about our species just as we would with any other species.

This is what I love about science- the fact that there is always something more being discovered and there is always new and upcoming discoveries

I feel like because the development of urbanization does not seem to be slowing down anytime soon, more and more species will be able to adapt and evolve to survive in these urban environments.

I wonder if the adaptions certain species have made to adapt to their urban environment would continue to be passed down even if they went back to living in their natural habitat.

Could sub-species be formed based on how each individual adapts to their new environment/ if the new environment splits their habitat?

If certain animals can eventually evolve overtime to adapt to their habitat being changed by the urban environment, will marine animals eventually be able to adapt to their environment being changed by anthropogenic activity?

Do rats, pigeons, bed bugs and cockroaches now have a higher fitness because they have adapted to the urban environment? Would they have a lower fitness if they were brought back to their natural habitat compared to being in an urban environment?

Is there a predicted percentage that this will rise to overtime? Will there be a point in time where urbanization will exceed the maximum capacity it can reach to and begin to create even more problems?

If this is the case-would the "lower-quality" individuals slowly become 'extinct' because they are producing less and less offspring. If the higher quality individuals continue to reproduce more than the lower quality individuals, I believe that due to natural selection the lower quality individuals would not be as fit and would not be able to pass their genes on as easily- therefore would a species soon become a population of all high quality individuals?

This is also a question I have- why is it that the majority of the time the females are choosing the males and not the other way around? Or why is it not an equal choice where it could be either the male or female choosing one another? Why did it evolve to be mainly females choosing males? Is this in some way more beneficial to the species?

There are also cases where the female tries to attract the male by having the vibrant colors or patterns or using unique sounds to attract them. In most cases it is the male trying to attract the female but this is not always the case which I think is something important to note.

Natural selection is something that is touched upon in almost all biology classes including this one. This whole course has always involved the topic of natural selection and will continue to do so as we move into the topic of sexual selection. Sexual selection and natural selection can go hand in hand because sexual selection is used to attract mates for reproduction and if an individual is unable to attract a mate they will not pass down their genes to the next generation and therefore their traits may not be carried on.

This advantage can may be because one individual has brighter, bolder, color and patterns that attracts a mate more than other individuals. Another way to attract a mate would be through sound. These factors all contribute in creating reproductive isolation between different species

This is known as intraspecific competition which is when organisms of the same species compete for limited resources.

Many animals have a mutualism where they both benefit one another which is important in helping them survive by being able to live peacefully together while also benefiting from the other organism.

Climate can greatly affect an individuals ability to survive as harsh temperatures can lead to freezing to death, drought, lack of food and water, bush fires, etc. We are seeing this first hand in the Australian bushfires which is destroying animals, habitats, and resources.

Shows that it doesn't always matter how many young you produce but how well the young is taken care of in order for it to survive. Therefore the fitness of the organism proves itself to be very important so that their genes can be passed on and they can survive and continue on their population.

This is important because although it is unfortunate that every being will suffer destruction it is what keeps population sizes to an optimal number based on the amount of resources available. Natural selection ties into this because the organisms that are less fit will not survive during these periods of time where it faces destruction.

This is essentially talking about the fitness of an organism which plays a huge role in natural selection

I did not realize population genetics was a part of evolutionary biology. I learned about population genetics in my genetics class last semester and would love to learn more about the connection between evolutionary biology and population genetics.

I find this very interesting and am also curious as to how much of this statement is true. I wonder how they are able to predict diseases and if they are able to predict them, why do new diseases continuously break out in populations without warnings such as the coronavirus. If they were really able to predict a disease they could start working on a vaccine for it before it rapidly spreads to numerous countries.

This is very important to know as our world is dependent on solutions to these problems and we need to know as much information as we can in order to solve them. These problems can be things such as climate change which is a huge issue in our world today.

I did not realize evolutionary biology can be applied to the management of endangered species. I find this very interesting because i am interested in conservation biology and specifically helping endangered species and learning how to manage and improve their conservation status.

I think this is both a very interesting and very important statement. It shows that science can be applied and used in all different subjects and is very important in various fields. I am curious to know specifically how these individual fields apply evolutionary biology to their work.
