![]() ![]() This would have enabled more subtle gestures and hence enhanced non-verbal communication. We think that enhanced social communication was a likely outcome of the face becoming smaller, less robust, and with a less pronounced brow. Did the human face evolve to enhance social communication? This reflects how modular the face is.Ī raised eyebrow, grimace, and squint all signal very different things. However, many of the details of this interaction between diet and facial shape are unclear because diet affects certain parts of the face more than others. In more recent humans, the transition from being hunter-gatherers to settlers also coincides with changes in the face, specifically the face becoming smaller. For instance, some early hominins had bony structures that suggested the presence of powerful muscles for mastication, or chewing, and they had very large chewing teeth, indicating that they were likely adapted for processing harder objects. Compared to our closest living relatives, the chimpanzees, our faces are more retracted and are integrated within the skull rather than being sort of pushed in front of it.ĭiet has been considered as an important factor, especially when it comes to the mechanical properties of foods consumed-soft versus hard objects. We also have less prominent brow ridges, and our facial skeletons have more topography. In broad terms, our faces are positioned below the forehead, and lack the forward projection that many of our fossil relatives had. How does the human face differ from that of our predecessors-and our closest living relatives? Since they are good to eat, sheepshead are targeted by anglers, so the handling of one after capture creates the possibility of being bitten or poked by their sharp dorsal fin spines.NYU News asked Lacruz to describe how we came to look the way we do. "They pose no threat to humans unless harassed. "I would not hesitate to swim in waters inhabited by these fish," says David Catania, a collections manager at the California Academy of Sciences, to Madison Dapcevich of. Unless bothered, the fish won't nibble on anyone. While the toothy sheepshead jaw may spook those unfamiliar with the fish, they pose no threat to humans at all. "It's a very good fight when you're fighting on the line, it's a really good catch, and it tastes very good," Martin told McClatchy News. Many Facebook users, including Nathan Martin, the angler who caught the fish, commented on how tasty these fish are, the Post reports. Despite being caught for sport, they are edible. The fish's front teeth are even coated with enamel, like the human incisors they resemble.Īnglers can find sheepshead fish swimming near the Atlantic coast from Massachusetts to Brazil. They'll eventually grow three rows of stubby, flat teeth in their upper jaw and two rows lining their lower jaw. Young sheepshead fish eat marine worms or any soft-bodied animal found within seagrasses until all their specialized teeth grow in, reported Scientific American's Becky Crew in 2013.Ī full-grown sheepshead will grow up to three feet long, reports Live Science. ![]() Because the sheepshead's diet consists of mollusks and crustaceans, their molars assist in crushing their prey's tough shells. The coastal critter was dubbed the sheepshead fish for the way its mouth resembles the muzzle of a sheep, the BBC reports. ![]() Must look elsewhere," wrote another user, per the Washington Post's Jennifer Hassan. "I think grandpa lost his dentures, and this fish found them," one Facebook user wrote. Photos of the catch shared to Facebook on August 3 prompted many comments from users astonished by the fish's set of jaws, reports Brandon Specktor for Live Science. The fish, also known as convict fish for their black and grey horizontally striped body and ability to steal bait, have large, beady black eyes and an uncanny grin that resembles a human smile. Last week, an angler casting a line off Jennette's Pier in Nags Head, North Carolina, caught a hefty and toothy nine-pound sheepshead fish ( Archosargus probatocephalus). ![]()
