Question
Chapter 1, Problem 11RQ
(a)
Summary Introduction
To determine: The initial obstacle faced by the theory given by Darwin on natural selection in evolution.
Introduction: Evolution is a necessary process that happens with time as it helps the new generation in adapting according to the environment. The natural selection theory of evolution is one of the most accepted theories.
(b)
Summary Introduction
To determine: The ways that helped the natural selection theory in overcoming the initially faced obstacles.
Introduction: All the theories given by Darwin were not accepted by the biologists. Some are still in controversies. The theory of natural inheritance is widely accepted and was supported by the particulate inheritance principle.

- Name the scientist who had also come to similar conclusion as that of Darwin about natural selection as a mechanism of evolution. Which place did he visit to come to conclusions?arrow_forwardIn lecture we discussed eight (8) lines of evidence that Darwin used to lay out his argument for the fact of evolution in his book On the Origin of Species (1859). Using your materials from lecture and the last chapter of the "Origin" that we read for section, 1) rank order these lines of evidence based on what you find the most to the least compelling. 2) Be sure to describe each of these lines of evidence and 3) discuss how they are, or not, relevant in the early 21st century. (From old pset1) Evidence Variation in domesticated species and breeding (artificial selection) Hierarchical classification (groups nested within groups) "Unity of type" - modification of the same basic structure (homology) Evident "fit" of organisms to environments (but imperfections) (adaptation) Structures without apparent function (vestigial structures) Similarity of organisms in early phases of development (embryology) Order in diversity through time in the fossil record (paleontology) Order in…arrow_forwardDo you think that Darwin would object to the neutral theory of evolution?arrow_forward

- Offically speaking, did Charles Darwin develop the theory of "evolution" or the theory of "descent with modification?" I know he coined the second term but I can't find if that's all he's historically creditited with.arrow_forwardCompare and contrast Lamarck’s scientifically invalid model of evolution (Lamarckian Inheritance) with Darwin’s scientifically valid model of evolution by Natural Selection. Though incorrect, why was Lamarck’s theory of mutability so revolutionary compared to other scientific thinkers of the time and preceding him? Why was Darwin’s (and technically Alfred Wallace’s) theories of mutability so revolutionary compared to Lamarck’s? What aspects of natural selection did Lamarck get right? What aspects did Lamarck get totally wrong? Remember to consider and give examples of mechanisms of inheritance on both the individual and populational level in Lamarck’s and Darwin’s evolutionary models, as well as the role environmental pressures playarrow_forwardBased on what you learned in lecture and Why Evolution is True, how can you explain the similarity between a cactus and a euphorb plant, despite the two Families being geographically distant?arrow_forward
