Natural Selection and Evolution of Rock Pocket Mouse Populations

Observations:
Most rock pocket mice have a sandy light-colored coat.
There have been populations of rock pocket mice that are found to have dark-colored coat.
These Sandy light-colored mice are found living in location where they blend in.
The dark-colored coat mice are found in areas with mostly dark rock so that they are able to blend in.

Questions:
What makes these Rock Pocket mice have a different colored coat?
Did the mice start out with a light colored coat or with a dark-colored coat?
How long did it take for the populations to evolve into different populations with different colored coats?
Did gene mutation cause a change in the coat color between populations of the Rock Pocket mouse?

Hypothesis:
Alternate hypothesis: Rock Pocket mice have different coat colors that help to their advantage that depend on their location through evolution.
Null hypothesis: Rock Pocket mice don’t have different coat colors that help to their advantage that depend on location through evolution.

The darker mice have a mutated Mc1r gene because they present a darker coat from the light-colored coated mice. This happens because of a mutation in the Mc1r gene that increases the production of eumelanin by melanocytes that then results in a darker coat. This is alternative to the lighter-coat mice who have a lighter coat because their Mc1r gene goes through no mutation resulting in a presence of melanocytes which produce melanin and therefore decrease the production of

Leopard Gecko 's get their name from the popular look of spots that resemble leopards they tend. Yet, leopard gecko 's can have many different ways of looking. They can range from a soft lavender color to as bright as an orange. Leopard geckos are very different from most of the rest of the lizard reptile community. Leopard geckos have eyelids that can actually blink and in general they are very sweet natured creatures.

They hide in high trees which will help them survive from other animals,predators. They have one of the darkest brown skin color on their body. Their enemy is jaguars,large birds,snakes,and humans. The only snakes that eat sloths are cobras rattle snake and some pythons.

Sloths are very strange animals with their sluggish behaviors, yet they are very interesting at the same time. Sloths belong to the mammalian order Xenarthra, which also includes armadillos and anteaters. There are two different kinds of sloths, the two-toed and the three-toed sloth. There are four species of three-toed sloths and two species of two-toed sloths. Two of these species of sloth can be found in the tropical forests of Costa Rica, the brown-throated three-toed sloth (Bradypus variegatus) and Hoffmann’s two-toed sloth (Choloepus hoffmanni).

Skin color has created a diverse population in society as we know it. Differences within race among various populations conclude that there was more than one evolutionary event. Today, while we don’t have fossil skin from our African hominin ancestors (Homo erectus), it’s probable that they were dark, as are African populations now.  Earlier ancestors may have had lighter skin. Now, take a look at our closest relatives, chimps and gorillas, their skin the actual parts underneath the hair are unpigmented.

Sloths usually only go the forest floor to defecate, this makes them very vulnerable but when in the trees their color, slow movement and the algae on them acts as camouflages. A sloth’s fur is specialized to grow in the away from the sloth’ body to protect it from the weather when the the sloth is upside down and some of the sloth’s fur have tiny cracks that can collect water .Sloths are folivores, they mainly eat leaves and plant material , some two toed sloth sometimes will eat insects and other small animals. Since sloths mainly eat leaves, it does not give them enough nutrients they need so they have specialized chambered stomachs to slowly digest their food. Sloths also have very low metabolic rates and they have low body temperatures. Researchers have found out that sloths in the wild actually sleep about 10 hours a day and don’t sleep for fifteen or more hours like captive

My pangrilla lives in the bamboo forest that has a lot of bamboo and trees. My pangrilla has black and white fur so when it's sleeping in the trees it blends in with the thick leaves. The pangrilla fur color is codominant ,white,and black. There are some pangrillas that are only black this shows Generic Version. Generic Version helps the pangrilla survive in its habit because it can live in area of the forest that the tree leafs are bigger and thicker.

Conservation of the Silky sifaka Possibly the rarest mammal in the world, the Silky simpona, or most commonly known as the Silky sifaka or Propithecus diadema candidus have a small home range in forests with elevations between 4101 ft. and 6152 ft. in north-east Madagascar (Andriaholinirina, Baden, Blanco, et. al and Gron, 2008).  The Silky sifaka belongs to the suborder strepsirrhini; due to their wet noses, infraorder lemuriformes; because they are a lemur, and family Indriidea, because they are a type of sifaka. (Gron, 2008). Silky sifakas are approximately 1.6 ft. in body length with their tail being roughly the same length and weigh about 13.2 pounds (Maria Correa, 2013).

How To Get Rid Of Mice In Your House If you hear gnawing or scuttling in your walls at night, you might have a mouse problem. You may also notice a foul odor, see greasy trails, or find rodent droppings around your home. Mice may be cute little animals, but they have no place running loose in your house. They are very destructive, smelly, and they can spread diseases.

Gene flow has become much more common in humans in the past few centuries due advances in transportation which can bridge the gap between two populations. However, for primitive species, gene flow is not as common because species can be easily separated by things such as bodies of water and mountain ranges. Natural selection is the ability of a species to adapt to its environment in an attempt to increase its fitness. Fitness, in relation to evolution, is the ability of a species to survive and reproduce. Natural selection is the selection of species that have the highest fitness.

Lemurs fur color range from red to black and their magnitude ranges from the size of a mouse comparison to a big cat and their weight is about five pounds. These herbivores hobby by swinging above in the trees rather than, traveling on the ground. Although, only the ring-tailed lemurs like to explore the ground. Their hands have digits and a superior grip that helps them ingest food, swing from tree to tree, and helps babies hold onto their mom's hair. Lemurs have great climbing skills and the claw behind each foot helps support their adventurous climbing skills.

Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).

Only in the last decade or so has it been realistically possible to address this question experimentally using population genetic approaches. On the basis of earlier studies in mice, and on studies in humans with various Mendelian disorders, many of the genes underpinning population variation in skin color have been identified. More recently, genome-wide approaches have identified other loci that appear to contribute to pigmentary variation. The ability to study sequence diversity from world populations has allowed examination of whether the observed variability is due to random genetic drift or is a result of natural selection. The genetic evidence taken as a whole provides strong evidence for natural selection, functioning so as to increase pigment diversity across the world's populations.
