Common Misunderstandings of Evolution: Part 1 While an open and honest debate is always a good thing, most of the time, when people are pointing out “problems” in evolution, their qualms arise from a misunderstanding of what evolution actually is and how the mechanisms of evolution actually function. Below are some of the most common misconceptions (or questions) in evolution and how science answers these concerns. Q1.) A.) In truth, evolution doesn’t explain anything about how life originated. How life originated is something completely different, called abiogenesis. Q2.) A.) This is, perhaps, the most well-known, as it is easily observed and demonstrated. In short, the organism is more “fit” for survival; this idea of “fitness” is central to natural selection. Q3.) A.) Evolution doesn’t really make a species better than its predecessors, it makes multiple species that are well suited for survival in their specific niche in the ecosystem at a specific period in time. Q4.) A.) Q5.) A.) READ NEXT: What’s Wrong With Evolution?

Planète+ The Biology Corner Google’s smart contact lens: What it does and how it works It’s a question that Google officials have clearly thought a lot about, said Joseph Lorenzo Hall, chief technologist at the Center for Democracy & Technology, who was briefed on the lens before the company’s Thursday announcement. Hall said that Google assured him that the data would not be added to the company’s banks of personal information gathered from other services. “The data will never hit Google’s servers,” he said. “That’s a forward-thinking affirmative claim that they’re making. The soft contact lens that Google is unveiling — it’s still a prototype — houses a sensor that measures the glucose levels in tears. Given the sensitive nature of the data, Hall said, Google has also said it will make sure any data transferred from the lens cannot be manipulated — something that could have potentially fatal consequences if patients inject the wrong amount of insulin. “It’s disruptive, and it’s painful,” Google project co-founders Brian Otis and Babak Parviz said in the blog post.
