1Around 1.4 million years ago, early human relatives crafted mysterious stone spheroids (球體) in the Middle East in attempts to make perfect spheres, a new study found.The finding showed the intention of early humans to impose a symmetry (對稱) on the stones, the researchers suggested.“It's possible these deliberately spherical stones had some sort of functional advantage over naturally rounded stones available in the landscape,”study lead author Antoine Muller, an archaeologist at the Hebrew University of Jerusalem, said.“And their tendency to become more spherical as they were made suggested a preference for symmetry and an appreciation of geometry(幾何).”
2Hundreds of stone spheroids, typically made from sandstone, have been unearthed at archaeological sites in Africa, Asia and Europe.The smallest one is just one inch across.The earliest spheroids are up to 2 million years old.But they span the entire era of stone tool-making,and some have been found at the New Stone Age and later sites that are only a few thousand years old.
3The researchers used mathematical analysis to determine that the spherical shape of some of the objects—which range from rough polyhedrons (多面體) to near spheres—was deliberate, likely worked on in stages and not accidental.Muller said,“The ones that were more‘finished’were more spherical, suggesting that this was one task they were aiming for.”
4They noted that earlier studies had seen symmetry in Acheulean bifaces,a type of stone tool dating from1.7million years ago,and this was thought to be the earliest evidence of“early humans imposing a geometric shape and symmetry on their stone tools”.But it now seems that the spheroids, which are older, may have had the same purpose—and perhaps other purposes as well.
5Muller said the study suggested that early humans may have been more cognitively(認(rèn) 知) advanced than previously suspected.“Our findings suggest that the people who made these spheroids could imagine something as abstract as a sphere and impose that concept in reality by shaping a stone,”he said.“That likely takes a great deal of forethought and flexibility,speaking to their remarkable cognitive and skilful abilities.”
1.Why did early humans add symmetries according to Muller?
A.They had advantages over other living things.

A.Those near spheres next to perfection.
B.Those accidentally rounded stone tools.
C.Those rough stones waiting to be rounded.
D.Those completed spheres far from perfection.
3.What can Acheulean bifaces be used to prove?
A.Stone tools needed no improvement.
B.Early humans pursued a sense of beauty.
C.Geometric shapes were everywhere then.
D.Spheres were the same as Acheulean bifaces.
4.What does Muller mean according to paragraph 5?
A.Shaping a stone was easy for early humans.
B.Early humans were frequently questioned.
C.Present humans underestimated early ones.
D.Early people skillfully made spheroids.
