关于人类起源的叙述,正确的是(  )

A.人是由上帝创造出来的

B.人是由黑猩猩经过长期进化而来的

C.人是由女娲用泥捏出来的

D.人是由森林古猿经过长期进化而来的

答案

在距今1200多万年前,森林古猿广泛分布于非、亚、欧地区,尤其是非洲的热带丛林,后来由于环境的变化,森林古猿朝两个方面进化,一部分森林古猿仍然以树栖生活为主,慢慢进化成了现代类人猿,如黑猩猩、猩猩、大猩猩、长臂猿等.另一支却由于环境的改变被迫下到地面上来生活,慢慢的进化成了人类,可见人类和类人猿的关系最近,是近亲,它们有共同的原始祖先是森林古猿,人类的进化过程是一个自然选择的过程.故D符合题意.

故选:D.

     Raymond Schneider politely made his way through crowds of customers as he made for the candy

bins at Dylan's Candy Bar in Manhattan. Since he was out of employment, Mr. Schneider, a

33-year-old designer, says he has become a person who always buys a lot of sweets every time he

shops for groceries.

"Sugar is comforting," he said. "There's nothing more stressful than growing financial insecurity (不安

全感) everywhere."

     The recession (经济衰退) seems to have a sweet tooth. As unemployment has risen, Americans,

particularly adults, have been consuming (消费) growing amounts of candy.

     Theories vary on exactly why. For many, sugar lifts spirits dragged low by the economy. For others,

candy also reminds them of better times. And not importantly, it is relatively cheap.

     At Candyality, a store in Chicago, business has jumped by nearly 80 percent and the owner, Terese

McDonald, said she was struggling to keep up with the demand for Bit-O-Honeys, and Sour Balls.

Many big candy makers are also reporting rising sales and big profits (利润).

     "It's not surprising." said Peter Liebhold, chairman of the Smithsonian Institution's work and industry

division. "During the Great Depression in the 1930's, candy companies stayed in business."
