An original model that would explain how regions of the genome that are copied later on facilitate the birth of new genes with specific functions in tissues and organs One of the most important processes in the life of cells is genome replication, which consists of making exact copies of the DNA in order to pass it on to their offspring when they split. In most organisms, from yeast to human beings, genome replication follows a set plan, in which certain regions of the genome replicate...

Natural Selection Shown To Promote Antigenic Evolvability

Ranjini Raghunath for redOrbit.com - Your Universe Online What is more useful? Having a superpower, or the ability to develop a superpower? Evolution, of course, picks the latter. Evolution favors the survival of the fittest. If a trait helps an organism adapt to a changing environment, that trait is favored and preserved by evolution. For example, when insects are affected by a pesticide, some of them develop resistance to it, while others die. Evolution targets these...

Secret Of Short Stems

Max Planck Institute Arabidopsis plants that only reach half their normal height have a mutation in the biosynthesis of the plant growth factor gibberellin The normal height to which plants grow is a critical trait. In the wild Arabidopsis thaliana uses the same genetic changes in the biosynthesis of the growth factor gibberellin to cut its size in half as found in semi-dwarf varieties of rice and barley that have been bred by people. When expressing the same phenotype, various plant...

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

Brett Smith for redOrbit.com - Your Universe Online It can be puzzling sometimes when someone else finds the taste of your favorite food to be disgusting, but research has shown we all perceive the taste of various compounds differently. A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the...

Two Mouths For One Worm
2013-11-07 11:58:54

Max-Planck-Gesellschaft A devious evolutionary path between genetics and environment Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....

Evolving multicellular algae in the lab, researchers discover why it is better to go it alone during reproduction Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now researchers led by University of Minnesota College of Biological Sciences postdoctoral fellow William Ratcliff and associate professor Michael Travisano have set a big piece of that puzzle into place...

Butterflies Offer Insights Into Evolution
2013-10-31 16:39:31

Michael Harper for redOrbit.com - Your Universe Online A new study from the University of Chicago finds it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another. After studying butterflies, the researchers found evolution can happen as the result of a process rather than a single event. In fact, in the case of butterflies, the beginning of a new species could begin with something as...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
