Brooding in invertebrates serves to protect embryos from stressful external conditions by retaining progeny inside the female body, effectively reducing the risk of pelagic stages being exposed to predation or other environmental stressors, but with

Shallow-water coastal areas suffer frequent reductions in salinity due to heavy rains, potentially stressing the organisms found there, particularly the early stages of development (including pelagic larvae). Individual adults and newly hatched larva

Marine sediments can contain B vitamins, presumably incorporated from settled, decaying phytoplankton and microorganisms associated with decomposition. Because B vitamins may be advantageous for the energetically intensive processes of metamorphosis,

In this chapter, Darwin explains how gradual evolutionary changes can explain why the members of all taxonomic groups can be linked into a single genealogical series. He explains why all of the smaller taxonomic groups of organisms, such as species a

In his opening chapter, Darwin talks about how domesticated animals and plants have gradually come to look as they do through the power of humans to select for the particular traits that they value over the course of many generations. The keys to thi

In this chapter, Darwin tightens the link between varieties and species even further, showing that the members of some plant and animal species can be successfully mated with members of other species and still produce viable offspring, offspring that

In this chapter, Darwin emphasizes that, for all plants and all animals in nature, far more individuals are born than can possibly survive: predation, competition, and physical stresses all take their toll, often in amazingly complex and surprising w

Throughout The Origin of Species, Darwin has been arguing that all modern species of animals and plants are descended from other species, many of which looked very different from their descendants. If he is correct, many asked, then why don’t scien

In this chapter, Darwin addresses a number of major criticisms that had been thrown at his theory of evolution by natural selection and survival of the fittest, particularly those delivered by zoologist St. George Jackson Mivart, who had initially be
