Researchers studied the thale cress (an Arabadopsis relative) which can have either a single or a double genome. Genome doubling is not good news: “It’s almost always a bad thing to have too much DNA, but we think that sometimes it makes for a ‘hopeful monster’ that just might flourish.” They seem to have found […]
The genome isn’t what it used to be.
If so, it’s remarkable outcome for genome mapping: So it has been dawning on us is that there is no prior plan or blueprint for development: Instructions are created on the hoof, far more intelligently than is possible from dumb DNA. That is why today’s molecular biologists are reporting “cognitive resources” in cells; “bio-information intelligence”; “cell […]
From ScienceDaily: When a building is damaged, a general contractor often oversees various subcontractors — framers, electricians, plumbers and drywall hangers — to ensure repairs are done in the correct order and on time. Similarly, when DNA is damaged, a molecular general contractor oversees a network of genetic subcontractors to ensure that the diverse cellular […]
The find kind of disappointed researchers who really wanted to know how humans come to use language but it is interesting in itself.
He thinks the Central Dogma of mitochondrial DNA needs to be rethought.
From ScienceDaily: University of Otago researchers have discovered information about a gene that sets primates — great apes and humans — apart from other mammals, through the study of a rare developmental brain disorder. … Dr O’Neill and research collaborators from Max Planck Institute of Psychiatry, Germany, then set forth to test the point that […]
A computer programmer looks at DNA … and finds it to be “amazing” code. From 2006 through 2017, Dutch entrepreneur and software developer Bert Hubert contributed from time to time to a web page where he listed many of the ways the workings of DNA can be likened to coding decisions by programmers. Some of […]
From ScienceDaily: Many wild and cultivated plants arise through the combination of two different species. The genome of these so-called polyploid species often consists of a quadruple set of chromosomes — a double set for each parental species — and thus has about twice as many genes as the original species. About 50 years ago, […]
The world’s simplest animal is trichoplax adhaerens. It is so simple that researchers wisely decided to forego the venerable Biological Species Concept that depends on an animal’s form (tricoplax doesn’t have much of a form) and just use genetics. But when evolutionary biologist Michael Eitel sequenced the genomes of several thousand of them, he was […]
Earlier this month, 15 genomes were released. The Vertebrate Genomes Project aims to sequence every extant vertebrate species—there are about 66,000—and to make them of the highest possible value. … “What we thought was a ‘genome’ back [when G10K was launched] really wasn’t suitable for in-depth studies,” G10K cofounder David Haussler, a computational biologist at […]
Seen from below: Professor Hugenholtz said the scientific community generally agrees that evolutionary relationships are the most natural way to classify organisms, but bacterial taxonomy is riddled with errors, due to historical difficulties. “This is mainly because microbial species have very few distinctive physical features, meaning that there are thousands of historically misclassified species,” he […]
And we are not sure which ones they are. From ScienceDaily: Research Centre (CNIO) reveals that up to 20% of genes classified as coding (those that produce the proteins that are the building blocks of all living things) may not be coding after all because they have characteristics that are typical of non-coding or pseudogenes […]
There were no external injuries. The fossil — discovered in the region of Yakutia — has its skin, hair, hooves and tail preserved. Yakutia is also famous for having found woolly mammoth fossils in the permafrost. Scientists from Russia’s Northeast Federal University, who presented the discovery Thursday, said the foal is estimated to be 30,000 […]
To cut to the chase, the system is a mess. What does that say for theories like neo-Darwinism which are based on the mess and depend on its swirling currents?
