Gregor Mendel – Father of Genetics




Augustinian monk and pioneer of genetics, Gregor Mendel, calculated the odds of inheritance in his monastery garden. In a German sermon, he preached the following homily, seamlessly intertwining scriptural interpretation with his scientific investigations:

“Jesus appeared to the disciples after the Resurrection in various forms. He appeared to Mary Magdalene so that they might take him for a gardener. Very ingeniously these manifestation of Jesus is to our minds difficult to penetrate. He appears as a gardener. The gardener plants seedlings in prepared soil. The soil must exert a physical and chemical influence so that the seed of the plant can grow. Yet this is not sufficient. The warmth and light of the sun must be added, together with rain, in order that growth may result.

“The seed of supernatural life, of sanctifying grace, cleanses from sin, so preparing the soul of man, and man must seek to preserve this life by his good works. He still needs the supernatural food, the body of the Lord, which received continually, develops and brings to completion of the life. So natural and supernatural must unite to the realization of the holiness to the people. Man must contribute his minimum work of toil, and God gives the growth.

“Truly, the seed, the talent, the grace of God is there, and man has simply to work, take the seeds to bring them to the bankers. So that we ‘may have life, and abundantly.’”


The Paris Biota Marine Fossils

Researchers studying rocks unearthed from a site in Idaho discovered a variety of 250 million year  fossils. They suggest that marine life bounced back more quickly than was thought after the 'Great Dying' of the Permian Period, which began about 299 million years ago. The Permian Period ended in the largest mass extinction ever known. Approximately 96 percent of marine species went extinct. 
The Paris Biota researchers found sharks, squid-like creatures, bony fish and creatures that looked like sponges and starfish. They found a fossil that appeared to come from a marine reptile that resembled the modern dolphin. The researchers believe that marine life recovered quickly with a large diversity in the Early Triassic, the period that followed the Permian.

Human Origins: The Data of Science and Scripture Align


Alice C. Linsley

The book of Genesis asserts that humans are a special creation and were created fully human from the beginning. Many people think this is a myth to be dismissed. Why should the belief that humans are a special creation be a myth? They appear suddenly on Earth about 4 million years ago and from the beginning show human traits: walk upright, created tools, hunted, controlled fire, ritually buried their dead. A. afarensis used polished bone tools to cut, chop and scrap. A. afarensis also had human dentition. In humans, the back teeth are larger than the front teeth (not so with apes), and the canines are not pointed. These early humans also lack the characteristic diastema or tooth gap found in apes.

Some of the earliest evidence of controlled fire by humans was found at Swartkrans in South Africa. Other sites that indicate fire use include Chesowanja near Lake Baringo, Koobi Fora and Olorgesailie in Kenya.
When Jeremy DeSilva (Boston University) compared the ankle joint, the tibia and the talus of fossil "hominins" between 4.12 million to 1.53 million years old, he discovered that all of the hominin ankle joints resembled those of modern humans. His research has shown that Australopithecus lacked the grasping toe typical of tree climbers, and its spine, pelvis, knees, and ankles were made for walking on two legs and not designed for tree climbing.

In 2011 researchers discovered jaw bones and teeth of four individuals in the Afar region of Ethiopia which date to between 3.3m and 3.5m years old. These archaic humans were alive at the same time as other groups of early humans, suggesting that it may be time to abandon the linear evolution hypothesis. Clearly, there were more archaic humans living in Africa 3 million years ago than has been generally recognized.

The discovery of a complete fourth metatarsal of A. afarensis at Hadar shows the deep, flat base and tarsal facets that "imply that its midfoot had no ape-like midtarsal break. These features show that the A. afarensis foot was functionally like that of modern humans." The February 2011 report was written by Carol Ward, William H. Kimbel, and Donald C. Johanson. Johanson worked with Mary Leakey.

Johanson and Leakey were scheduled to speak at a Nobel Symposium in Sweden in May 1978. The conference honored Mary Leakey, who received a medal from the King of Sweden for her scientific investigations. Leakey was embarrassed when Donald C. Johanson announced that his Afar Triangle finds were ape, and included Mary Leakey's 4 million year old Laetoli specimen (jaw bone LH4) from Tanzania as an exhibit. Leakey would have classified her Laetoli finds as Homo/human. She expressed her regret that “the Laetoli fellow is now doomed to be called Australopithecus afarensis.” Australopithecus means ape of the south.

New World Map the Most Accurate


The Japanese architect Hajime Narukawa claims to have resolved the centuries-old problem of how to draw an oblate spheroid Earth on a flat plane. This is the map of the world that Narukawa produced. It looks very different from the version produced by Gerardus Mercator in the 16th century. Mercator devised a map with straight lines of longitude and latitude which helped in sea navigation.


AuthaGraph World Map


Unlike the traditional Mercator map, which overstates the size of Greenland and Europe and minimizes that of Africa and South America, the AuthaGraph World Map retains parity of area to a 3D projection.

Go here to read how Narukawa achieved this more realistic map of the world.

Humans Have Created 208 Species of Minerals


Humans have created 208 species of minerals that exist solely due to human activity. These minerals represent nearly 4 percent of the 5,200 mineral species recognized by the International Mineralogical Association (IMA), and most can be attributed to mining in locations around the world.

Wringing a Wet Cloth in Space


Ever wonder what would happen if you were in space and you wanted to wring excess water from a wash cloth? Some students asked that question and an astronaut performed the experiment.
