Denisovans, Humans and the Chromosome 2 Fusion

With that as background, we are now prepared to appreciate a new finding that comes from genomics work done on the Denisovan hominids, an archaic species that is more closely related to Neanderthals than to us, but that nonetheless interbred with some anatomically modern humans as they migrated out of Africa and populated the globe. (For those not familiar with the Denisovans, or the evidence for our interbreeding with them, both Darrel Falk and I have written on this previously, here and here). Recently, a more detailed understanding of the Denisovan genome was published, and nested in the new information is the discovery that the Denisovans share the 46 chromosome set with the same fusion that we have. This strongly supports the hypothesis that the fusion event predates the separation of our species. If we were to represent this on a phylogeny, we can now place this event with more accuracy than before ..

Has the dark matter mystery been solved?

Unseen dark matter has been invoked several times to solve problems in astrophysics and cosmology. Historically the most significant problem has been the rotation curves of galaxies, particularly spiral galaxies. Using the Doppler Effect the speeds of the stars and gases in the disk regions of spiral galaxies can be measured. See Figure 1.

By now hundreds of thousands of galaxies have been measured this way. What is observed is that the speeds of the stars, and the gases beyond where the stars are observed, are much greater than it would appear Newtonian physics allows for. 

As a result it has been suggested that there is an invisible halo of cold non-interacting matter. This putative invisible halo has the needed gravitational effect on the stars and gases but it cannot be seen, hence it is called dark matter. Dark matter is alleged not to be normal atomic matter, made from protons and neutrons (which are known as baryons), but some sort of slowly moving (cold) exotic non-baryonic matter. Weakly Interacting Massive Particles (WIMPs) were suggested.

Science of God Conference

The Professor and the Prophet in an exclusive exploration of the marvels of God….Join us in this discovery.
Looking at the vast expanse in the cosmos above or the depths of the blue oceans below, they speak volumes of the splendor of God who was directly involved in His creation. As humans we marvel at the enormous complexity which is breathtaking. God also gave us wisdom and an enormous capacity to explore His creation, which today tell us specific details of the "how" and "what" of His creation.
As he unleashes His love and shower His glory upon us, we obediently study His word, get closer to Him and adore Him day by day for this beauty and marvel of this creation.
Here is your opportunity to take a tour of the specific examples from the field of science , a deeper exposure to His word and a chance to bathe in His love and Glory
While we tackle issues, such as, the Big bang, expanding universe....

quantum theory, Fibonacci sequence, Uniqueness of His blood, DNA, Heart intelligence and more, you will also have adequate time to worship, release your addictions and hear from Him.......
Join us at Hotel Taj on 29 April
