Charles Darwin和自然选择理论(Charles Darwin and the Theory of Natural Selection ) 演化的观点在1859年11月被强烈地聚焦,当时查尔斯·达尔文出版了《On the Origin of Species by Means of Natural Selection》(图1.16),这是有史以来最重要和最有影响力的书之一,。《The Origin of Species》阐述了两个主要观点。
Of the 24,090 trait pairs examined, 6743 pairs (or 28.0%) have a CORE that deviates significantly from CORM at the false discovery rate (FDR) of 5% (Table 1, Data S1), suggesting that natural selection has shaped the coevolution of many trait pairs. To investigate whether the above ...
The theory of evolution was published by naturalist Charles Darwin in his book On The Origin of Species by Means of Natural Selection or The Preservation of Favored Races in the Struggle for Life, in 1859. In a letter to Asa Gray, Darwin confided: "...I am quite conscious that my specu...
Evolution can be either adaptive, in which case it has been driven by and shaped by natural selection. It can be neutral, in which case it's been dominated by drift. Or it can be maladaptive. So evolution does not only produce things that work well. Evolution produces things in which st...
We know that the biological world's diverse catalytic repertoire is the product of evolution by natural selection, but we have little understanding of how Nature's tinkering generates new functions. Sometimes we are (un)lucky enough to catch them in the act - e.g., the acquisition of ...
Evolution (进化) can perform extraordinary makeovers; today’s airborne songbirds evolved from the wingless, earthbound dinosaurs that wandered millions of years ago. But some organisms seem to be unchanged — in other words, escape natural selection. The coelacanth, a modern-day fish, is nearly...
We present one such theory, concerning evolution by natural selection, and describe the arguments and evidence that underlie the theory, which we regard as a well‐founded hypothesis. Some methodological problems associated with testing this type of theory are discussed, as well as the role of ...
The publication of Darwin’s theory of evolution by means of natural selection pushed modern science into a new paradigm. Darwin changed the way scientists think of organisms, including humans, and in doing so challenged the Christian worldviews of his day. Even in the twenty-first century, Darw...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
to finish their two‑hour percussion jam. Three of the six djembe sampled here have metal jingles called seh seh (flat tin plates with wire rings fixed round the edges) attached to make the sound buzzier, a common African practice; the remaining three are jingle‑free and beautifully ...
