Common Objections and Misunderstandings
Evolution is just a theory, and therefore might not be true:
- > Problem with the word theory; not everyday term for theory (tentative guess as to whether
something is true or not), but scientific term for theory (s
Origins of the Genus Homo
- 1st Fossils to which researchers agree to apply the same genus name-Homo-as
ourselves date from ~2.5mil years ago, attracting such names as homo habilis,
homo rudolfensis, and later homo ergaster and homo erectus.
These early H
Why does modification occur?
- How is it that animals are so well suited for for their ecological niche?
- Design in nature can be amazingly useful and complex (bat echolocation) but there can
also be design oddities in nature (whale pelvis; whats its pur
A Highly Selective History of the Theory of Evolution The Basics of Natural
Selection and Genetics
- research shows that most people in even quite educated sectors of the population
misunderstand basic aspects of the theory of evolution in the most fundam
Origins of Homo Sapiens:
- Fossils that are almost indistinguishable from bones of modern humans were
found to be within ~200,000 years ago, with the oldest dates in Africa.
- > referred to as H. sapiens, and referenced as anatomically modern humans
Evolution by natural selection, in a nutshell: 4 key elements heredity, competition,
variation, and natural selection.
- these key four elements provide the solutions to the problems of design and history.
- these four elements work as follows:
- Problem of history:
- phalanges -> fingers (pg. 4)
- cytochrome c: found across many plants and animals; protein with 104 chain of
amino acids. (pg. 4-5)
- > single difference in the chain between humans and rhesus monkeys, but over
20 discrepancies bet
Species in time
- Problems with not just categorizing a phylogeny of living species but even harder
is extinct species.
- > the principle of reproductive isolation cannot practically be applied to extinct
= Usual solution: use different species
Ongoing selection at the phenotypic level:
- biologists often do not know which, if any, genes contribute to variation in a trait, but
they can nonetheless look for evidence of selection at the phenotypic level.
- > one way of testing: whether there are n
Our place in nature:
- Human being: Homo sapiens.
- > provides us with a context of differences and similarities.
- > helps us guess about when/why certain important features of human life arose.
- > lets us look at how species are classified, how they re
Article Summary: The Lure of the Simplistic
Theory of Evolution has been a questionable topic in which the evolution has
occurred for many years therefore, many research has been done in perspective to
different philosophers and currently many philosopher
