Fungal pathogens cause more than a billion human infections every year, resulting in more than 1.6 million deaths annually. Understanding the natural history and evolutionary ecology of fungi is helping us understand how disease-relevant traits have repeatedly evolved. Different types and mechanisms of ...

化石包括石化了的生物遗体和遗迹(生物运动痕迹)。从化石中可以看到古代动物、植物的样子,从而可以推断出古代动物、植物的生活情况和生活环境,可以推断出埋藏化石的地层形成的年代和经历的变化,可以看到生物从古到今的变化等等(摘自维基百科)shows the gradual change of species over time。
A. Human activities. B. Random mutations. C. Environmental changes. D. Scientific E. xperiments. 相关知识点: 试题来源: 解析 C。在进化过程中,环境变化主要驱动着物种的改变。环境的改变会对生物产生选择压力,使得那些适应环境的生物个体更容易生存和繁殖,从而导致物种的遗传特征逐渐发生改变。人类活动对物种...

Humans are the most successful species on Earth thanks to multiple key traits that have been gained through evolution that has naturally developed over hundreds of thousands of years. One of those traits is the human brain, which is the most powerful brain from all the other animal species on...
