地图上一朵花
Ⅰ 地球上第一朵花长什么样子
花自古便被人类视为美的象征,世上有成千上万种花卉,但从来没人知道地球上第一朵花到底是怎样。欧洲生物学家日前用计算机模拟出世界上第一朵花的模样,看来就像白莲花和白百合的结合体。
Dr Jason Hilton from the University of Birmingham, UK, who was not
involved in the study, said: "The structure and organization of the
ancestral flower has remained enigmatic. For instance, we don't know if
the oldest flowers were unisexual or bisexual, or if they were
pollinated by wind or insects."
英国伯明翰大学的杰森•希尔顿博士没有参加这项研究,他称:“鲜花始祖的结构和组织依然还是个谜。例如,我们不知道最古老的花朵是单性的还是双性的,或是依靠风还是昆虫授粉。”
To reconstruct the appearance of the first flower, the scientists
recorded the features - such as the petals and sepals - of the flowers
from 792 living species.
为了重现世上第一朵鲜花的外观,科学家记录了792种现存花卉的花瓣、萼片等外形特征。
They mapped the distribution of these features on to the evolutionary
tree of flowering plants enabling them to build a picture of what
flowers looked like at key points in their history - including the last
common ancestor of all living flowers.
他们将这些特征分布绘制成开花植物的进化树,从而重现花卉在关键的进化节点上的样貌,其中就包括所有现存花卉的最后一个共同祖先的样子。
The first flower is reconstructed with petal-like structures arranged
in a whorl, so each petal appears in the same plane, like a common lily
(but with more whorls), rather than in a spiral, where petals overlap
in a spiral arrangement around the stem, like a lotus.
第一朵鲜花被重构成齿轮状排列的花瓣状结构,像一朵常见的百合(但花瓣更多),所有花瓣出现在同一个平面里,而非像莲花一样花瓣围绕花茎重叠呈螺旋状排列。
"For some of the features we studied, the result was surprising,
especially the fact that organs (such as sepals and petals and the
stamens) were probably arranged in whorls instead of spirals, as
commonly assumed for the ancestral flower," said Hervé Sauquet.
埃尔韦•索凯说:“关于鲜花始祖特征的一些研究结果让我们感到意外,特别是它的器官(如萼片、花瓣、雄蕊)可能是齿轮状排列的,而并非是人们通常认为的螺旋状”。
Sex evolution in flowers has been highly debated. Flowers can be
unisexual or bisexual and this study infers a bisexual early flower with
both male and female organs.
花的性进化一直备受争议,鲜花可以是单性或双性的。这项研究推断花卉祖先是两性的,同时拥有雄性和雌性器官。
"This study is important as it tells us how complicated the ancestral
flower is likely to be - now the search is on to find it or something
closely resembling it in the fossil record. That's if the model is
correct - only time (and further study) will tell," said Jason Hilton.
杰森•希尔顿说。“这项研究意义重大,因为它告诉我们鲜花始祖可能有多复杂,现在研究者正努力在化石中搜寻它或此类东西。只有时间和进一步研究才能证明,这个鲜花始祖模型是否正确。”

Ⅱ 我玩失落之城好像少了一朵花,我有红花蓝花粉花还有一朵是什么在哪里
还缺少黄色的花,那是夏天之花,需要把季节转换为夏季才能找到,夏天之花在场景36,可以在地图里找到。
Ⅲ 世界上第一朵花开在哪里
您好,世界上第一朵花开在哪里?
目前公认世界上最早的有花植物是发现于版中国辽西热河生权物群的辽宁古果,也就是说,世界上第一朵花在中国辽宁省朝阳北票市盛开。
辽宁古果约生活在距今约1.2亿—1.5亿年中生代侏罗纪晚期至白垩纪早期,属古果科,已经具备了花的基本特征,有花蕊,豌豆大小的果实8到12粒。对于研究被子植物的起源具有重要的实物参考价值。于2010年发现于中国辽宁葫芦岛的中华星学花生活在大约1.6亿年前,它可能成为新的世界上最早的花,但由于其在分类上存在争议,可能属于裸子植物而非有花的被子植物,其具体分类还需进一步研究。但不管怎样说,世界上第一朵花开在中国辽宁省西部是不存在争议的。
