This rapid origin and diversification of animals is often referred to as “the Cambrian explosion.” Scientists have asked important questions about this explosion for more than a century.Why did it occur so late in the history of Earth?The origin of multicellular forms of life seems a relativel...
The concentration and dispersal of continental blocks occurred several times during the Earth's history, so why it did not occur earlier than Rodinia? The delivery of vast amounts of nutrients to the oceans associated with the uplift of continental lithosphere, the oxygenation level plus the ...
One way to think of what deep learning does is as “A to B mappings,” says Baidu’s Ng. “You can input an audio clip and output the transcript. That’s speech recognition.” As long as you have data to train the software, the possibilities are endless, he maintains. “You can in...
Why did the Triassic period end?Question:Why did the Triassic period end?The Triassic Period:The Triassic Period was the first period of three in the Mesozoic Era. The Triassic began approximately 252 million years ago and ended approximately 201 million years ago. The Triassic Period began with...
Briefly describe the concept known as the "red tide". What environmental damage can this phenomenon cause? Catastrophism was the prevailing theory as to why the earth looked like it did in the 1600s and 1700s. What was the theory about, why it was popular...
I feel like one reason I’m not Protestant is that I see more honestly looking at the history, and I think many other Protestants will agree with this, at best you have a very thin thread, and it’s like the Cambrian explosion and the fossil record. It’s like this thin thread, and...
the Internet—that, it turns out, are essential to making neural nets work well. “This is deep learning’s Cambrian explosion,” says Frank Chen, a partner at the Andreessen Horowitz venture capital firm, alluding to the geological era when most higher animal species suddenly burst onto the ...
Explain what the Cambrian explosion is? Why was it significant? Why might some regions in deserts serve as runoff sinks (i.e., have more water flowing in than out)? 1. Why is natural gas often associated with oil in the ground? 2. How do geologists look for ...
Explain what the Cambrian explosion is? Why was it significant? Describe the steps that lead to death due to dehydration. Why predators don't always drive their prey to extinction? Explain why the thymus atrophies and disappears as we age. Why does plasmolysis occur? Explain why w...
What is a mass extinction, and when did each of the five largest mass extinctions occur? What are some mechanisms that have been proposed as causes of mass extinctions? Is gradual evolution the same as anagenesis? Explain how speciation...
