If you’ve ever noticed a slimy film of algae on a rock, chances are you didn’t pay it much attention. But some of these overlooked species hold clues to one of the greatest mysteries of evolution, scientists have found: how plants arrived on land.On Thursday, researchers published the genomes of two algae that are among the closest known living relatives of land plants. They already had some of the key genes that plants would need to thrive on dry land.
Why doesn’t Professor Behe go along with famed Evangelical Christian scientist Francis Collins, and others?
Modern scientists have force-fed the theory of evolution on Americans for decades, leaving the impression it is settled science. But that is hardly the case, as many brilliant minds have criticized and questioned the theory, including David Berlinski, a self-described “secular Jew.”
Biology encodes information in DNA and RNA, complex molecules finely tuned to their functions. Although, other nucleic acid-like polymers are known, yet much remains unknown regarding possible alternatives for hereditary information storage. Using computational methods, scientists explored the chemical space of stable nucleic acid analogues, finding over one million variants. This suggests a vast unexplored universe of chemistry relevant to pharmacology, biochemistry and efforts to understand the origins of life.
A cache of 118 million-year-old fossilized dinosaur and bird feathers has been recovered from an ancient lake deposit that once lay beyond the southern polar circle.
