That could make a huge difference, because as you get older, your body changes, so what if when the Aye-Aye was young, it could see in color? But as it got older, it started to lose that sight? Did they say what ages the Aye-Ayes were that they tested? Maybe it'll help if they test it. Well, i think they should also try, young and old.

I think they're really cute, and this blog is interesting, i'm a big animal lover, good job with this. This is an awesome blog, i never knew that much about Aye-Aye’s until now.

Ireally liked it and learned a lot. The Aye-Aye doesn't really need color vision according to the scientist Verelli. http://www.biology-online.org/articles/aye-ayes-it-preservation-color-vision.html Verelli talks about how the aye-aye is a primate and is related to humans in the evolutionary line, but unlike humans the aye-aye can't see in color. According to Verelli it isn't really important for the aye-aye to have color vision because it is mostly out at nightime. Verrelli also mentioned that it is a nocturnal primate. Nocturnal animals don't need color vision at night. They only need to see the lights and darks to see for predators and their prey. So it really isn't that important for this nocturnal animal to have color vision to live in its enviroment. Great post Matt. Ireally liked it and learned a lot.

I never knew of this animal before an this post explained all about the animal very well. To me, I thought that the experiment could have been a lot better than it was. UAccording to the scientific method, it says that the experiment needs to be done multiple times in order to make sure that the first result wasn't an accident. Well, this experiment only done twice, and for an experiment this experiment is really important on the study of Aye-aye's so they should do it four or five times. Another thing I noticed is that they only used eight Aye-aye's in their experiment. That is really poor because as the scientific method also states that the more subjects you have in a experiment, the margine of error gets slimmer and slimmer. According to these stats, if you have 10,000 subjects, there would be a 1% change that there was an error in a experiment, as appose to 10 subjects which would mean that there would a 31% chance that their was an error in the experiment. The only problem about that is that because Aye-aye's are an endangered species, you can't get a lot of them in the first place. Have they fixed these flaws, they would have a much more convincing conclusion. http://www.sciencebuddies.org/mentoring/project_ideas/Soc_participants.shtml http://www.sciencebuddies.org/science-fair-projects/project_scientific_method.shtml Great job Matt!!

I really enjoyed learning about an animal I knew nothing about. In my opinion the Aye- Aye is one of the ugliest animals I’ve ever seen. Also I find them very interesting. The fact that they don’t see in color is very interesting. I found out some more information on the Aye-Aye. Aye Ayes have very sharp claws and primate like hands. The average life span for an Aye Aye is 20 years long. They are mammals and they are Omnivore. They are also very small only 14 to 17 inches from head to tail. They also only weigh about four pounds. In fact their bushy tail is bigger than their body. Did you know that Aye- Ayes are the only primates that use echolocation to find prey. Echolocation means to find prey by using the prey’s echo’s. http://www.thefreedictionary.com/echolocation http://animals.nationalgeographic.com/animals/mammals/aye-aye/ Great post Matt!

There is one for blue, one for green and one for red. The aye ayes were chosen because they are nocturnal. Since nocturnal animals may not need color vision to see at night, the genes were speculated to have deteriorated over time. After tests were turn it was determined that the genes were completely intact with no mutations. This changed how the scientist viewed how color vision developed in nocturnal animals. http://www.biology-online.org/articles/aye-ayes_preservation_color_vision.html Humans and some other primates have three genes that give color vision that are called opsins.

I never knew that the aye-aye's had such a distinctive compilation of physical features (as you mentioned in the first paragraph). To answer one of your questions, I think it's extremely important to understand the aye-aye's vision. The comprehension of other animal's abilities can not only help protect those animals, but these could facts could eventually aid mankind in evolution- but potentially create new cures or treatments (like the horseshoe crabs we learned about in class). Here's a great site about a study done on the aye-aye's vision: http://www.physorg.com/news108143658.html This is a really fascinating post, Matt.

Aye Ayes scientific name is Daubentonia madagascariensis and to add to the first part of your post, they don't only eat grubs from trees, they are omnivores eating different nut and nectar from the Traveler palm tree. They are also the largest nocturnal primates. The reason this nocturnal primate doesn't have color vision is because they would need bright light to detect colors and night time does not supply these animals with enough light so they don't see in color. http://anthro.palomar.edu/primate/color.htm http://www.animalinfo.org/species/primate/daubmada.htm http://www.bristolzoo.org.uk/learning/animals/mammals/aye-aye I really like your post Matt.

As it has been determined that the Aye Aye can see some colors through studies that show Aye Ayes being able to see in colors because of a fully functional green opsin gene. This gene uses opsin proteins in order to recognize colors, which is astounding because usually nocturnal mammals are not expected to fully recognize colors with a lack of light. Take for instance a boy eating jelly beans in the middle of the night, he will not be able to differentiate the colors easily. While an Aye Aye, because of its genes is able to recognize these colors easily even when there is a minimum amount of light. These similarities prove that we as humans may be related to the Aye Ayes and have gained both part of our color vision and nocturnal vision from a similar ancestor.
