Darwin's Dangerous Idea makes extensive use of cranes as an analogy. Darwin provided just such an alternative: evolution. [8] Besides providing evidence of common descent, he introduced a mechanism to explain it: natural selection. According to Dennett, natural selection is a mindless, mechanical and algorithmic process—Darwin's dangerous ...
Microsoft PowerPoint is a presentation program, [8] created by Robert Gaskins, Tom Rudkin, and Dennis Austin [8] at a software company named Forethought, Inc. [8] It was released on April 20, 1987, [9] initially for Macintosh computers only. [8]
When citing sources in Wikipedia articles, the citation must clearly support the material as presented in the article, per the verifiability policy.It helps to give a page number or page range—or a section, chapter, or other division of the source—because then the reader does not have to carefully review the whole cited source to find the relevant supporting evidence, which promotes ...
The history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world.
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Irreducible complexity (IC) is the argument that certain biological systems with multiple interacting parts would not function if one of the parts were removed, so supposedly could not have evolved by successive small modifications from earlier less complex systems through natural selection, which would need all intermediate precursor systems to have been fully functional. [1]
[5] [6] The challenge for abiogenesis (origin of life) [7] [8] [9] researchers is to explain how such a complex and tightly interlinked system could develop by evolutionary steps, as at first sight all its parts are necessary to enable it to function. For example, a cell, whether the LUCA or in a modern organism, copies its DNA with the DNA ...
On November 8, 2005, there had been an election in which the eight Dover school board members who voted for the intelligent design requirement were all defeated by challengers who opposed the teaching of intelligent design in a science class, and the current school board president stated that the board did not intend to appeal the ruling.
