It's been 150 years since Charles Darwin published On the Origin of Species. Yet his ideas remain as central to scientific exploration as ever. QUEST follows entomologist David Kavanaugh, who predicted that a new beetle species would be found on the Trinity Alps. Find out if his prediction came true…
Today QUEST TV broadcasts its half-hour documentary "Chasing Beetles, Finding Darwin," which tells the story of California Academy of Sciences beetle expert David Kavanaugh's unusual prediction that a new species of beetle would be found in Northern California's Trinity Alps.
As I mentioned in a previous post, February 12th marks the 200th birthday of Charles Darwin and the 150th anniversary of the publication of the "Origin of Species".
All across the world, scientists are leading a month long celebration of the man & his science, widely seen as the public hero of science & science education.
Last blog I talked about the Transcaucasian mole vole. This little burrowing mammal has lost its Y chromosome over time. Now both males and females have only a single X. I focused on how scientists can't yet figure out how there are any male mole voles running around. This week, I want to focus on what this means from an evolutionary perspective.
These fish can tell us a lot about ourselves. Species often end up a different color when their environment changes. And humans are no exception. When people moved out of Africa tens of thousands of years ago, they were dark-skinned. Now when we look around Northern Europe or parts of Asia, we see much lighter […]
Genetically, we're all pretty much the same. A massive volcanic eruption 75,000 years ago may be why. Lake Toba is all that is left of the volcano that nearly wiped out mankind.Last blog I talked about how East Africans are genetically more diverse than Asians. Who are genetically more diverse than Native Americans. From all […]
I love my cell phone. We have a serious relationship. One that may be biologically predetermined. Let me explain. On New Year's Eve I brought my phone with me to San Francisco's Ocean Beach, where I traditionally go, rain or shine, to watch the year's last sunset. I was by myself, but I wasn't alone. […]
NOVA commemorates the historical evolution trial of 2005. Credit: NOVAIf you tune in or point your web browser to PBS this week, you'll see a whole bunch about evolution. It's not Charles Darwin's birthday, but it's a celebration that may one day carry much more significance: it's the two year anniversary of the Kitzmiller vs. […]
In search of the common ancestor of all mammals, UC Santa Cruz scientist David Haussler is pulling a complete reversal. Instead of studying fossils, he's comparing the genomes of living mammals to construct a map of our common ancestors' DNA. His technique holds promise for providing a better picture of how life evolved.
