Top Stories 0 Comments   Share   No one knows if Kevin Kolb will be in Arizona on Thursday but we do know where he won’t be.According to sources who talked with the Philadelphia Inquirer, Kolb won’t be at Eagles training camp.Kolb, despite being under contract, won’t be at Lehigh University for the Eagles’ first training camp practice, an NFL source said Wednesday. The Eagles backup quarterback won’t be here, the source indicated, because a trade was still being worked out.It makes sense for both parties for Kolb to avoid Eagles camp. As many reports have indicated, the trade between the Eagles and Cardinals seems more of a matter of when than if. By showing up he’d be nothing more than a distraction.center_img Cardinals expect improving Murphy to contribute right away What an MLB source said about the D-backs’ trade haul for Greinke D-backs president Derrick Hall: Franchise ‘still focused on Arizona’last_img read more

Now, a new study shows that, by borrowing techniques from archaeology, marine biologists can pick out otter “utensils” from other rocks.Many primates have also been shown to use stone tools. Recently, researchers have blended biology and archaeology to identify patterns of wear on such tools used by apes and monkeys—dating some as far back as 700 years. The findings made researchers wonder whether such methods could also be used on sea otters.Many sea otter rocks get discarded to the sea floor, but some turn up on beaches, where the otters bang their shelled prey against boulders protruding from the sea. One such place, an estuary in central California called Bennett Slough, offered researchers an opportunity to examine the otters’ feeding behavior—and the rocks they dropped after smashing up dinner. Over 10 years of observations, the team identified a so-called “otter signature.” Rocks used as tools had points and ridges that were lighter in color than the rest of the rock. Next, the researchers examined 421 additional rocks in the area and found that 77 were being used to break open shellfish, they report today in Scientific Reports. Shattered mussel shells littering the rocks nearby corroborated the findings, showing telltale breakages that matched the otters’ blunt force modus operandi.With their distinctive patterns, the stones could tell scientists when sea otters started to use tools. The researchers say understanding how long this behavior has been around and how it spread through populations could also help illuminate the broader question of how tool use in other mammals—including humans—evolved.last_img read more
