Human Variation/ Race

1.) One of the environmental stresses that has faced humans is getting through the cold weather. Cold weather can cause serious problems such as hypothermia and can also be harmful and very life threatening. Hypothermia is a condition in which core temperature drops below the required body temperature. Ways that hypothermia can be caught is by drinking cold water, putting alcohol into your body, and also due to low temperatures.

2.) Shivering is a short term adaptation, due to the muscles in your body shaking which then warm your body up.

• Red cheeks is a facultative adaptation, due to the temperature of our skin falling below 10 degrees celsius. Thermo stress plays a roll to how people react to the cold, such as age and fitness level is the way our bodies react differently to the cold.

• A developmental adaptation would be a large body mass. People who have a large body mass tend to stay warmer than those that don't have a large body mass. Throughout the different seasons throughout the year the bigger person is always warmer then the small bodied person.

• A cultural adaptation is clothing, because having warmer clothing you will necessarily stay warmer. Warm clothing for the cold weather would be considered by wearing a warm jacket and warm pants and a pair of warm gloves.

3.) The benefit through the study of human variation through environmental characteristics is getting to view how we adapt to things in different ways. Information can definitely be useful, such as to being capable of understanding why people adapt to things in certain ways.

4.) The way we would use race to better understand variation on the adaptations, would be to showing and comparing each race and how each race reacts differently to other races. It is a way of showing how each race adapts to the environment, and it is a good way to know what human variation and how each is different.

                                                                                                                                                              

Piltdown Hoax

       The Piltdown man was a hoax in which bones were presented as fossils remained of other previous human beings. The types of bones discovered were parts of a skull and jawbone and these such things were found and collected from a pit. The Piltdown hoax was discovered in 1912 in England. Charles Dawson and Arthur Smith Woodward are the persons which who discovered the hoax. This was said to have started when Dawson found a jawbone that he believed was an ape's jaw, but then realized it had human teeth. After doing research it was said that the hoax would have taught us that people cannot always rely on scientists for answers to be given on this type of work due to the Piltdown hoax being forged.
       The human faults that come into play is self-esteem, lying, and having trust to fit in with others involved in the society. These faults highly impact this process in which Dawson and Woodward were involved and was the cause to why these scientists were viewed as lier's due to the Piltdown hoax.
       The fraud that had been discovered in the process of the Piltdown hoax was when the scientists discovered that the bones dated back to 100 years old when they processed them using fluoride. Another discovery in this process that was made was that the bones clearly wouldn't match after they had gone through the process.
       I wouldn't necessarily say that it isn't possible, but it would clearly be possible removing human factor from being involved in science, but i don't believe it would be the correct decision if it occurred due to brains having a bigger impact when critical thinking, and me not trusting the computer to doing ll the research just because of all the fraud that is occurring. Using the human brain is much rather reasonable to discuss, and go over many other thoughts that humans have in mind when discussing situations.
      The life lesson i always have in mind and that is useful to me is to always do my own research when i am not 100% sure with what others have to say, i would rather spend time researching and thinking it over myself than to always have the trust in what others have to say.

Analogy/Homology Blog

1.) Homologous trait:

A.) The forelimbs of a frog and Gecko's possess Homologous traits.

B.) The homologous trait that frogs and gecko's share is the forelimbs that there body inherits. The differences that these two species exhibit is that frogs are born in water and gecko's are born on land. A frog is an amphibian and a gecko is a reptile. Both species are attainable to catch their food with the long tongue's that they have.

C.) The ancestor of these species is Gerobatrachus hottoni. It is believed that the ancestor has a tail of a lizard and head of a frog.














2.) Analogous trait:

A.) Frogs and grasshoppers inherit analogous traits.

B.) These two species both relax on long legs, and both have eyes on the side of their head. Many frogs are green just like grasshoppers, and both are capable of hopping when they move from place to place.

C.) Grasshoppers originally came from a species called Eoproscopia martilli. Just like the first part the ancestor for frogs is Gerobatrachus hottini. We know that this species inherits this trait because frogs have the shape of a gerobatrachus hottini and the grasshoppers have the shape of the eoproscopia martilli.

1.) I believe that Thomas Malthus had the most influence over Darwin's development of his theory of natural selection. He clearly had a negative influence due to Malthus not begin a natural scientist and him being an economist but he still had the potential to over power Darwin.

2.) The contribution that Malthus made to the scientific community was population growth. For instance, the population growth in humans and species would influence food growth, hunger, and diseases. Malthus's work helped inspire Darwin's theory on the natural selection. Malthus was also better off remembered for his contributions to Darwin's theories.

3.) In the link on "How does evolution work" talks about the natural selection, and the change in population. These are the points affected by this individual's work and have been influenced by Thomas Malthus. For instance, Darwin's theory is trying to discover how new species arrive, and with that being said is where the natural selection theory comes to hand. These factors were influenced by Malthus due to his work ethic on population change on humans and animals.

4.) Darwin could have clearly developed his theory of natural selection on his own, but it made it much rather easier for him due to Malthus's work inspiring him to research the natural selection much clearly.

5.) The attitude of the church affected Darwin because he knew it could lead him to trouble, but his new way of thinking led him to finally present his ideas to the world on his publication of his new book. Darwin described h.is change as being a natural selection. These were the contributions made throughout Darwin's theories
