Questions for Creationists.

A bit of turning the tables in the direction they should be. Feel free to add your own well thought out queries to the irrational. Evolution should NOT ever be on the defensive, when a creationist asks a ridiculously trite strawman of a question, retort with one of my personal favorites:

Here are a few questions I like to ask, and they are only the tip of the iceberg (I can formulate hundreds more, but we must start somewhere):

What do you have to say and how do you scientifically explain endogenous retrogene insertions without evolution by common descent?

Endogenous retroviral insertions are arguably the best example of molecular sequence evidence for universal common descent. Endogenous retrogene insertions are molecular remnants of a past parasitic viral infection. Occasionally, copies of a retrovirus genome are found in its host's genome, and these retroviral gene copies are called endogenous retroviral sequences. Retroviruses, like HIV, make a DNA copy of their own viral genome and insert it into their host's genome. If this happens to a germ line cell (i.e. the sperm or egg cells) the retroviral DNA will be inherited by descendants of the host. This process is rare and fairly random, so finding retrogenes in identical chromosomal positions of two different species indicates common ancestry.

Post your links proving evolution

HERE IS A COMPILATION OF A FEW HUMAN ANCESTOR FOSSILS

Talk Origins is an excellent source for discussion on how humans got here.

Here is an assortment of free evolution downloads from the NCSE.

The following list are individual examples of proof of evolution:

Entire Genome of Extinct Denisovan Humans Decoded from Fossil

  According to clever  folks at the Max Planck Institute, they have been able to sequence the entire Denisova genome using 10 milligram of a finger bone fragment that was found in the Denisova-Cave in Southern Sibiria. The Denisovans are a representative of an Asian group of extinct humans related to Neanderthals. Here's the link : http://www.sciencedaily.com/releases/2012/02/120207133602.htm

Scientists Prove Plausibility of New Pathway to Life's Chemical Building Blocks

 

A group from The Scripps Research Institute has proven an alternative pathway to those sugars called the glyoxylate scenario, which may push the field of pre-life chemistry past the formose reaction hurdle, reports Science Daily.

The welath of the Cradle of Humankind

In my readings of this site to date I noticed that while theories have been discussed and evidence pointed to, there has been little to show where a vast wealth of evidence for evolution has come from. In fact in a search I know of one passing referral by Tapey (speaking of which my apologies mate, I didn't realise you were also Sefrican untill recenlyy - see me intro heh heh)

 

In South Africa we have a few major paleantologically wealthy sites from where a great many diverse fossils of early hominids have been discovered. The links brough on with these fossils add a great deal more evidence for the process of evolution, not just within humans but several plant and animal species as well.

 

The following links should prove interesting reading as a matter of fact. I will start with the most obvious (wikipedia) despite the fact that I'll likely catch some flack for that but it does give a good brief overview, a light starter to the meat and potatoes of the evidence you could say Sticking out tongue

Scientists Discover New Clue to Chemical Origins of Life

Evolution of Complexity Recreated

ScienceDaily (Jan. 8, 2012)— Much of what living cells do is carried out by "molecular machines" -- physical complexes of specialized proteins working together to carry out some biological function. How the minute steps of evolution produced these constructions has long puzzled scientists, and provided a favorite target for creationists.
In a study published early online on January 8, in Nature, a team of scientists from the University of Chicago and the University of Oregon demonstrate how just a few small, high-probability mutations increased the complexity of a molecular machine more than 800 million years ago. By biochemically resurrecting ancient genes and testing their functions in modern organisms, the researchers showed that a new component was incorporated into the machine due to selective losses of function rather than the sudden appearance of new capabilities.

Short Term Memory - Unambiguous Proof Brain Stores Data Using Gamma and Theta Waves

 

 


Experiments conducted at the Nencki Institute of Experimental Biology in Warsaw have shown that the more gamma cycles fall on one theta cycle, the larger capacity of short-term memory in humans. A typical chart of brain’s electric activity (EEG) is shown at the bottom. (Credit: Nencki Institute)

ScienceDaily (Dec. 15, 2011) — Short-term memory plays a crucial role in how our consciousness operates. Several years ago a hypothesis was formulated, according to which capacity of short-term memory depends in a special way on two cycles of brain electric activity. Scientists from the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw have now demonstrated this experimentally for the first time.
