FK Action Project for Population Unit#3 " Lobsters"

     Hello reader, this is my Action project for population unit 3. For this assignment we were supposed to select an organism of our choice ( I chose a lobster),  list it’s  name, habitat (with a picture), and extinct ancestor ( also with a picture). We were then supposed to compare an organism to it’s extinct ancestor, ask three guiding questions about the organism (one of which must be quantitative such as how much does your organism weigh?), create a set of data points and say the mean, median, standard deviation, first quartile, third quartile, variance, state are process on how we got all those numbers, create a box and whisker plot, create a new eniverment for the organism and say how it would do and site all of are sources 

    Lobsters or Homarus americanus evolved from an extinct Aegirocassis benmoulae, a 7 foot long ( idk what to call this beast) thing Around 409 million years ago in the Atlantic ocean was the first lobster ever. Given how old lobsters are I had to go prehistoric and found the Aegirocassis benmoulae.  Even though this is a lobster's closest ancestor, it is nothing like a lobster. It is 7 feet long, does not have claws, and ( I would estimate) at least 20 times it’s weight. Though it is believable that the Aegirocassis benmoulae is the lobsters ancestor because they both have a sharp exoskeleton and glans at the front of their face. The most distinct feature of a lobster is are, the symmetric pair of claws used to catch prey, coloration on their exoskeleton due to a genetic mutation that is barely known about by science, special hairs with nerve endings to detect more faint odors of prey, and two urinary glands in their head to communicate via odor with other lobsters. A lobsters common habitat is 40 degrees Fahrenheit salt water, with coral, and plankton.

Guiding Questions: 

*  Do Lobsters Feel Pain? 

Jury is still out, there is a big debate among marine biologists, I personally believe that lobsters have to feel some kind of pain because it is a living being, but there is strong evidence that there brain can't process pain, at least not like other creatures. " Animal rights activists and some scientists argue that lobsters' central nervous systems are complex enough that they can feel pain.

There is no conclusive evidence about whether lobsters can feel pain.

While lobsters react to sudden stimuli, like twitching their tails when placed in boiling water, the institute suggests that they do not have complex brains that allow them to process pain like humans and other animals do. In 2014, a scientist from Queen's University in Belfast argued that lobsters and other crustaceans probably do feel pain, on the grounds that crabs in a study learned to avoid a hideaway where they were repeatedly given an electric shock.

A Norwegian study from 2005 concluded the opposite: lobsters do not have brains, so they do not feel pain."

 

* Are lobsters bugs?

Although these organisms appear to be very different, plenty of evidence suggests that the lobster and the cockroach are more similar than many people might think! They are both arthropods with segmented bodies, exoskeletons made of chitin, and a need to molt as they grow.Don't be too grossed out - the cockroach and the lobster, probably shared that common ancestor about 525 million years ago.

* How much does a lobster typically weigh?

16 - 64 oz

weight range (data points): 16, 25, 30, 32, 37, 41, 48, 50, 53, 59, 64

Mean: 41.36

x( data point)	(x - Mean)	( x - Mean)^2
16	-41.36	643.1296
25	-41.36	267.6496
30	-41.36	129.0496
32	-41.36	87.6096
37	-41.36	19.0096
41	-41.36	0.1296
48	-41.36	44.0896
50	-41.36	74.6496
53	-41.36	135.4896
59	-41.36	311.1696
64	-41.36	512.5696
	sum of ( x - mean)^2	2,224.55

 variance: 2,224.55/10 =  222.45

Standard deviation: 14.91 ( square root of variance)

plot and whisker chart:

Median: 41 

1st quartile: 30 

3rd quartile: 53

New environment: the middle of the Saudi Arabian dessert: sandy, 80 - 120 degrees Fahrenheit, completely lacking water, and beating sun, small rodents, a couple desert flowers, and bugs live in this environment

This new environment is almost the exact opposite of the lobster's natural  habitat which is at the bottom of the freezing Atlantic ocean. 40 degrees Fahrenheit salt water, with coral, and plankton
