Profile

afarcomp3.jpg Afarensis is a 3.5-2.8 million year old hominin from the Kada Hadar member of the Hadar formation in the Middle Awash, Ethiopia. He is approximately 41 inches tall, weighs approximately 60 pounds and has a cranial capacity of a whopping 410 cc (approximately). Afarensis is currently considered to be transitional between apes and humans and displays some traits of both. Since he spends a lot of time on the couch watching monster movies, some observers question whether he is an obligate biped (although no one has observed him climbing a tree). He also has a blog called Transitions:The Evolution of Life His previous blog can be found here.

"With the first link, the chain is forged. The first speech censored, the first thought forbidden, the first freedom denied, chains us all irrevocably." Jean- Luc Picard, Star Trek: The Next Generation

"But the limit of tolerance for these human foibles is obtained when the proponent of a questionable scientific doctrine endeavors to maintain it against all possible odds by misrepresentation, misinformation and suppression of contradictory data, and by insinuating unfairness in opponents of his views."
Franz Weidenreich, Morphology of Solo Man


"Man stands alone in the universe, a unique product of a long, unconcious, impersonal material process with unique understanding and potentialities. These he owes to no one but himself, and it is to himself that he is responsible. He is not the creature of uncontrollable and undeterminable forces, but his own master. He can and must decide and manage his own destiny."
George Gaylord Simpson, Life of the Past


Yeah he's the Dick to the Dawk to the phd, he's smarter than you he's got a science degree! Yeah he's the Dick to the Dawk to the phd, he's smarter than you he's got a science degree!
Unknown

Whoever fights monsters should see to it that in the process he does not become a monster. And when you look into the abyss, the abyss also looks into you.
Frederich Nietzsche


But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.
The Declaration of Independence

The Experimental Darwin:

How Much Earth Could an Earthworm Move, If an Earthworm Could Move Earth?

It's a profoundly interesting question and Charles Darwin experimented to find the answer. I bet you all thought I had forgotten about my series on Darwin's experiments! Darwin came up with a couple of different methods for answering the question....

Darwin Experiments With Site Formation Processes

Okay, it was really about mold formation, but the experiment itself sounds like something that would make Michael Schiffer (for those of you unfamiliar with him, Schiffer's work primarily centers around the processes - natural or manmade - that go...

Darwin and the Cell: Not Just Protoplasm

Intelligent Design proponents are fond of saying that Darwin considered the cell to be just a formless blob of protoplasm. Behe's Darwin's Black Box is a good example of this kind of silliness. Few IDiots realize that Darwin was, in...

The Experimental Darwin, Tuesday Edition: Darwin and His Seeds

I was researching something different when I encountered some, previously unknown to me, experiments Darwin did with seeds....

Darwin and the Give and Take of Science

One of the key aspects of science controversy - that is people disagree with you and say so. Liu-Ochman flagellum evolution paper paper is a good example. Disagreements are a crucial aspect of how science progresses. In this example Darwin...

Darwin on Self and Cross Fertilization

It is a truism in science that experiments raise more questions than they answer. Darwin encountered this phenomena during his experimental career as well. Case in point, in The effects of cross and self fertilisation in the vegetable kingdom Darwin...

Darwin Admits a Mistake

In addition to being a great example of Darwin exploring a problem and performing experiments based on those explorations, this next example has one added point of interest. Darwin admits to making an error in a previous work. The admission...

Because One Can Never Say Enough About Carnivorous Plants

Darwin, as you may know, wrote a book devoted to carnivorous plants called, appropriately enough, Insectivorous Plants. In this experiment Darwin is using the Venus Flytrap. To set the stage: The sensitive filaments are formed of several rows of elongated...

Darwin Grows Some Plants

This experiment comes from The effects of cross and self fertilisation in the vegetable kingdom. Darwin describes the book thusly: This book will form a complement to that on the Fertilisation of Orchids, in which I showed how perfect were...

Darwin and His Worms

I had thought about not doing a post on Darwin's experiments today - since it is a holiday and all- but didn't want to disappoint my readers. So here I be, chained to the computer for you noble readers. Today's...

Darwin and Insectivorous Plants

In this experiment Darwin is trying to demonstrate that the papillae of Drosera rotundifolia (the common sun-dew) function to absorb nutrients and such. From Insectivorous Plants:...

Darwin Goes to Seed

Darwin, as mentioned in a previous post, was concerned with how islands could be populated. To that end he looked at a number of different ways seeds could be transported. Demonstrating that islands could be populated from organisms on continents...

A Simple Experiment

This comes from The Expression of the Emotions in Man and Animals. One of Darwin's reasons for writing the book was to refute the suggestion, by Charles Bell, that: "...man is endowed with certain muscles solely for the sake of...

Seeds and Such: Darwin Experiments with Plant Dispersal

One of the objections to Darwin's theory concerned the spread of plants and animals across the planet - particularly to islands. A number of people proposed solutions ranging from special creation to land bridges. Darwin had some objections to most...

The Experimental Darwin: Reader's Favorites

I have had several people mention their favorite Darwin experiments (in the comments to the first post in this series), so I thought I would, occasionally, highlight them. This one was mentioned by David Winter, if memory serves. This example...

Darwin Does an Experiment in Cognitive Psychology

One of Darwin's more interesting, and least widely known, works is The expression of the emotions in man and animals. According to the Complete Works of Charles Darwin Online: This is an important member of the evolutionary set, and it...
