Why past generations regarded women as the weaker sex is a mystery to anyone who has examined the question objectively, for they are far stronger than men—outliving them in pretty well every society in the world. Partly that is because men are more violent, and their violence is largely directed at other men. But partly it is physiological. Men seem to wear out faster than women do. Yet no one knows why.
Madeleine Beekman of the University of Sydney and her colleagues, however, have a hypothesis. They think at least some of the blame lies with subcellular structures called mitochondria (线粒体), which provide the body with its power by burning glucose and using the energy thus released to make a molecule that is biology’s universal fuel.
Mitochondria are amusing. They are descendants of bacteria that teamed up with the ancestors of animal and plant cells about a billion years ago. They retain their own genes, which is where problems start. To avoid fights between genetically different mitochondria in the same cell, most species have arranged for their mitochondria to come from only one parent—usually the mother so that a male’s mitochondria are stuck in an evolutionary dead end. They can neither evolve in male-specific ways nor be passed on to the next generation.
Male and female physiologies are sufficiently similar for this not to be a central problem, but Dr. Beekman thinks it may matter at the margins. She observes that one disease, caused by a faulty mitochondrial gene, occurs in only 10% of women whose cellular power-packs include the damaged gene, but in 50% of men whose mitochondria are so hindered. The gene in question, in other words, is less likely to harm a woman than a man. She then lists a lot of other diseases, including ones far commoner that sometimes have a mitochondrial component, and speculates that some of these may prove to be either more common or more serious in men than in women. As far as her literature search can show, this is not something that has yet been looked into.
Part of the reason for this absence of information may be that few doctors think like evolutionary biologists, so they fail to ask appropriate questions. Dr Beekman’s hypothesis may turn out to be wrong, but sounds remarkably
plausible
and certainly worth investigating. [br] The first paragraph implies that females________.
选项
A、are less prone to fatigue than males
B、are usually physically weaker than males
C、should not be considered the weaker sex
D、suffer from gender discrimination now
答案
C
解析
文章第一段第一句的大意是:每个社会当中,女性的寿命都高于男性,可是女性一直被认为不如男性强壮。这种观点似乎无法解释。作者认为我们不应该把女性视为the weaker sex(弱势群体)。
