Evolution?
"The natural act of crawling" - most animals crawl on four legs, and people start out crawling; it's a natural movement."First tentative steps" - tentative means hesitant; your first steps are shaky and tentative.Therefore, this phrase means that the first shaky steps seem to defy or rebel against the natural crawling movements that most animals use.
faceted means natural
The changing of life over time was first proposed by Greek philosophers ca. 600BCE (Anaximander, Empedocles). Similar hypotheses have been proposed between then and the 18th century CE, but it was not until the 18th century that such proposals became the subject of critical thought and empirical research. Diderot and Buffon were French philosophers who proposed hypotheses similar to common descent and natural selection back in the 18th century. It was also in the 18th century that natural philosophers first began structured investigation of the fossil record, and that the thought that life changes over time became firmly embedded in natural philosophy. Before Darwin prominent names in the history of evolutionary thought are: Lamarck, Grant, Saint-Hilaire. Robert Chambers first proposed a form of common descent - though one in which all other animals were steps on a ladder leading towards modern man. It was not until Charles Darwin that universal common descent, the 'tree of life' view, was formally proposed.
natural descent
No, it's the other way around: descent with modification is what you need for natural selection to happen.
Natural descent is a child that is born naturally through the will of male and female reproduction. Unnatural descent may be those born through a surrogate, or through in-vitro fertilization.
Natural descent is basically another term for generations (as in a family-line). Legal descent is a term that deals with inheritance rules that were established to describe what happens if someone passes away and leaves no legal will.
He explained them in terms of descent with modification, common descent and natural selection.
English descent.
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
"Foslett" does not have a standard or recognized meaning in English. It is possible that it is a typo or a misspelling of another term. If you provide more context, I may be able to offer a more accurate explanation.
a descent of a male or father
