Harvard Biologist Admits - We Know Nothing About Brain Evolution

Science journals have featured countless stories about the evolution of the human brain. Scientists are puzzled since humans have much bigger brains than any other species. Their suggested explanations have often been mutually exclusive. For instance, the old text book explanation relied on eating meat but a few years ago an article in New Scientist, a popular science magazine, suggested that eating starch was the secret of brain growth. But both explanations fail to answer why other meat or starch eating species do not have big brains.

At the recent AAAS (American Association for the Advancement of Science) annual meeting in Boston, Richard Lewontin, a distinguished biology professor at Harvard University, acknowledged that stories about human brain evolution have not been based on facts. Reporting on the meeting for the journal Science, Michael Balter quoted Lewontin as saying, "We are missing the fossil record of human cognition, so we make up stories." The title of Balter's article seems to be an admission of sorts: "How Human Intelligence Evolved--Is It Science or 'Paleofantasy'?"

According to professor Lewontin, it is fantasy. Lewontin suggests that there is much cause for pessimism in the study of human origins. Science reporter James Randerson of Britain's Guardian newspaper was even more brunt, saying, "We know nothing about brain evolution." Randerson went on to summarise Lewontin's reasons for pessimism. "The handful of hominid fossils stretching back 4m years or so" cannot tell us whether any of them were our ancestors. We "do not have the have the faintest idea what the cranial capacity [of a fossil hominid] means". Moreover, we do not even know which hominids walked upright and which did not.

Lewontin is well-known for his outspokenness. In 1997 he wrote in The New York Review of Books that scientists often choose to make up "unsubstantiated just-so stories" because they "have a prior commitment, a commitment to materialism... Moreover, that materialism is an absolute, for we cannot allow a Divine Foot in the door."

Obviously, the scientific community cannot ignore Lewinton's recent conclusions. If the ruling paradigm (naturalism or the view that nature is all there is) leads us into a blind alley, might there be something wrong with it?

Joel Kontinen is a translator and novelist currently living in Finland. His background includes an MA in translation studies and a BA in Bible and Theology. He likes to keep up-to-date on science news and often comments on creation/evolution and origins issues.

Bats as Pets?

Bats are the animal kingdoms only flying mammal and they are nocturnal (active mostly at night). They are quite social, roosting in sites where they can group together, and eat hundreds of insects per night to maintain the energy they need.

Although many find bats to be intriguing and even beautiful creatures, they should actually never be kept as pets. When we keep pets, we want to provide them with comfort and love, helping them grow to their full potential. When bats are kept as pets, though, they live in great terror and stress and lose their right to reproduce. Wild bats live over 25 years, but bats kept as pets rarely live longer than one year.

(In addition to this, there are several laws protecting bats from being kept as pets.)

While bats cannot be kept as pets, there are ways to provide for them. One of these is by building a bat box which can work as an alternate roost for bats. There are many varieties of kits available for you to buy with instructions on how to build it. After its built, though, youll need the perfect location.

First, if bats can be seen in an area at dusk, the area is likely to be a good spot to support a bat box. The box should be placed at least ten feet above the ground with its opening facing south-southeast, and it should receive at least seven hours of direct sunlight.

Also, bats are more likely to choose a box that is within 1500 feet of a permanent stream or water supply, as bats need plenty of water. Another consideration is to locate the box within 30 yards of a tree line to provide cover from predators.

It is also important to note that the bat box will be primarily used only during the summer months by bats, and that if the box is disturbed in any way during the first summer of its placement, the animals may not return. When they choose a roosting place, though, they are likely to be annual visitors.

Bat houses were actually first invented in Pennsylvania and are used for a variety of reasons. They provide low maintenance, environmentally friendly insect control, and they can be used to coax bats out of areas where they are causing a problem. They also create a great opportunity for those wishing to be able to keep the animals as pets you can view the interesting creatures without damaging them.

Bat species in general have been in decline during recent years, due in part to the removal of old trees. In building a bat box, not only do you provide yourself with an interesting sight, but youll also be helping preserve the animals species!

What Makes a Pet Exotic

According to the dictionary, the only thing that a pet requires to be considered an exotic pet is to be something that is not indigenous to a particular region. However, according to that definition, any poodle or even a little Cairn Terrier or even a Siamese cat would technically qualify as an exotic pet. So there must be something else that defines the parameters regarding what does and does not make a pet an exotic pet.

Further research indicates that exotic can also include anything that is considered to be "exotic in nature" or have to be something that is unique and in some instances, often misunderstood. This would certainly seem to be a much more applicable definition when it comes to exotic pets. I seriously doubt that you could find any animal experts online who would consider a common alley cat to be an exotic pet simply because it did not grow up in the alley directly behind your home.

Exotic pets are usually both unique and relatively rare. In many instances, they are exotic snakes such as boa constrictors and pythons which people may keep for a variety of reasons. Some people get exotic pets to overcome personal fears. Other people may keep exotic pets because of a deep-seated passion for misunderstood animals and reptiles. Still other people may keep exotic pets simply as conversation starters or a point of interest in order to entice others and pique their interest about pets and animals.

Fortunately, you do not have to worry about what constitutes an exotic pet or separates it from a simple domesticated animal. If you want to find the perfect pet, all you have to do is look around for the pet that you want. It does not even matter what your personal reasons for wanting an exotic pet may be. If you want to find the pet of your dreams, classified ads for pets online are all over the place.

From the relatively mundane but extremely soft and cuddly cat, to the very protective guard dog, it is very easy to find a pet online. If your personal preference is for more exotic animals, do not despair. Not only can you easily find classified ads for exotic animals online, you can also find out about any special needs or requirements that they have as well.

Maybe you have always wanted that tarantula or an iguana or maybe even some of the more exotic birds, but you feared that you did not live in a suitable environment to take care of such exotic species as a pet. Now, your answer is only a search away and you can find out everything that you need to know about virtually any type of pets online.

Granted, it would be wise to find out as much as you can about an exotic species before you consider moving one into your home. There may be extenuating circumstances that would prohibit you from owning the pet of your dreams. Fortunately for you, you can find out everything you ever wanted to know about any and all exotic pets online. Your answer is only a click away.

Ball Python Breeding

Today, I am going to talk to you about Ball Pythons and their Breeding.

Ball Pythons reach their sexual maturity at around three years old or about 1000+ grams. The ideal weight for a breeding Ball Python is 1500+ grams. At this weight they are more likely to lay more eggs. In the Herpetology, we call eggs a clutch. Each female is different in that they do not lay the same amount from one to another. A normal clutch of eggs is around 6-7. A female in prime condition can lay around 10-12 eggs.

Breeding season in Ball Pythons starts when the temperatures drops and the Moisture level increases. I keep my temps at about 85 during the day and about 75 at night. This time usually occurs around November, and lasts till around January. Eggs are usually hatched out around April to May. Most breeders will artificially incubate the eggs to control temps and moisture better, although some will leave the eggs with the female to hatch them out. The problem with this method is it's hard to control the environment.

The overall time it takes from copulation to birth is about 7 months 21 days. This varies though, with when your introducing the female to the male and when you start changing the environment.

I hope you enjoyed this post and if you have any further questions, visit our site. You will find some additional facts there as well as snakes, and books for sale. While visiting the site be sure to become a member of the Ball Python Forum.

Protection from All Dangers Through Dream Interpretation

Dream messages primarily function to protect you from the craziness inherent in your anti-conscience that constantly tries to invade and destroy your human side. On the other hand, dream interpretation protects you from all dangers of life.

The information you receive regarding the person you love is the most important part of the dream messages, especially at the beginning of your adult life. The unconscious protects you from the wrong person, who will only make you suffer and prepares you for the right person, by showing you how you can eliminate all the mistakes of your character and behavior, so that you'll have a balanced relationship, without fights and misunderstandings.

You can predict the future and learn the intentions of the others around you. Thus, you can avoid conspiracies against you or correct possibly negative outcomes before facing the negative consequences.

Many people told me that they never saw a dream predicting anything and they don't believe that this is possible.

However, predictions through dreams are very rare for those who don't care for their dreams and don't take notes.

The unconscious that creates dreams is a genius that organizes your body functions and everything else in this world. If you wish to really learn everything you can from your own dreams, you must care for them. If you are indifferent, you cannot utilize this gift.

Further, you must be transformed and prepared to learn the truth before time. You must know what to do when facing problems; otherwise, this vision will not help you in any way.

First of all, you must develop your personality and get rid of all your traumas, fears and complexes. Then you can start learning many other things and changing many things in your life as well.

The wise unconscious is a serious and careful doctor that will not reveal anything if you are not prepared to accept your future and if you cannot change something that will upset you. You will see dreams with predictions only when they are necessary and helpful.

Dream interpretation is not a crystal ball that will show you the future whenever you desire, but it is in fact far better because in addition to predicting the future when you are prepared to learn it, you can also correct it. Your knowledge is not passive.

Many people believe that whenever something bad is predicted the future cannot be changed. Even ancient Greeks believed that one cannot escape his or her own destiny.

This is true only for those who ignore why we suffer and why things go wrong with us. For those who interpret their dreams, the real reasons for the appearance of their problems and suffering are known, as well as their solutions.

Prevent Depression and Craziness through the scientific method of Dream Interpretation discovered by Carl Jung and simplified by Christina Sponias, a writer who continued Jung's research in the unknown region of the human psychic sphere.
