Molecular biology fills gaps in knowledge of bat evolution

One in five mammals living on Earth is a bat, yet their evolutionary history is largely unknown because of a limited fossil record and conflicting or incomplete theories about their origins and divergence. Now, a research team including University of California, Riverside Biology Professor Mark Springer, has published a paper in the Jan. 28 issue of the journal Science that uses molecular...

Same mutation aided evolution in many fish species, Stanford study finds

After decades of laboratory work studying how animals evolve, researchers sometimes need to put on the hip waders, pull out the fishing net and go learn how their theory compares to the real world. According to a Stanford University School of Medicine study published in the March 25 issue of Science, Mother Nature is more predictable than lab experiments suggest. In a diverse group of fish...

Researchers trace evolution to relatively simple genetic changes

In a stunning example of evolution at work, scientists have now found that changes in a single gene can produce major changes in the skeletal armor of fish living in the wild. "Our motivation is to try to understa...

Family trees of ancient bacteria reveal evolutionary moves

A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth's development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University assistant professor of geomicrobiology in the Department of Earth & Planetary Sciences in Arts & Sciences, studying Cyanobacteria ?bac...

Great White shark evolution debate involves WSU Lake Campus geology professor

A significant debate is currently underway in the scientific community over the evolution of the Great White shark, and Chuck Ciampaglio, Ph.D., an assistant professor of geology at the Wright State University Lake Campus, is right in the middle of it. The issue is if the Great White, one of the most feared predators of the sea, evolved from the huge prehistoric megladon shark or if its a...

Monoclonal Anti-Body To Revolutionize Brain Cancer Treatment

The use of monoclonal anti-body (mAb) L2G7 could revolutionize treatment of Glioma, the most common type of primary brain tumor. Surgery, chemotherapy and radiation are the only available treatment options for this type of cancer. // However, there is a significant risk of physical inability and cognitive impairment associated with these treatment forms. The results of the study can be found in...

Selective eating just an evolutionary trait?

Babies will put almost anything in their mouths. But as children get older, they become more selective about what they eat,// particularly if they have not tried it before. Green vegetables and meat can be particularly troublesome.But scientists say thousands of years ago toxins in plants could have harmed children, and meat carried a high risk of food poisoning.So it makes sense that...

Crooked teeth may be due to evolution and overcooked meals

According to Peter Lucas of George Washington University, while presenting a paper at the AAAS Meeting in Washington,// US, chopping of vegetables to bite size pieces and cooking them to into mashed textures may be one of the reasons that our teeth are growing crooked and badly formed. Thus congenital bad shaped teeth may be a direct result of evolution than anything else. Human teeth...
