Q

3 main parts in Darwins theory

A

1) Inheritance -> gleicher vorfahre
2) variation

- > SURVIVAL OF THE FITTEST

Q

Gaps in Darwins theory

A
  • wasn’t understood what origin of life was

- no idea how variations in characteristics were passed down to generations

Q

Reactions to evolutionary theory

A
  • many accepted evolution but not mechanisms he proposed
  • speculation about duration of natural selection & time necessary for species to change
  • basis for social Darwinism

Q

Evidence for evolution - then

A
  • diversity of living things
  • variation within single species
  • appearance and disappearance of species
  • comparing fossils!
  • comparing embryos
  • distribution of species in many lands
  • variations in species dependent on how long they were separated

Q

Eugenics (positive, negative)

A
  • set of beliefs and practices that aim to improve the genetic quality of human population
  • negative eugenic: discourage reproduction by those with undesirable traits
  • positive eugenics: encourage reproduction by those with desirable traits

-controlling reproduction

Q

Misunderstandings with Evolutionary theory

A

1) There is NO DIRECTION in genetic changes
- > genetic material has no knowledge of the environment, cannot change in desirable direction

2) Organisms do NOT become BETTER or stronger

Q

Francis Galton ( 1822-1911)

A
  • influenced by Darwin
  • searched to find evidence for inheritance of features -> especially mental qualities
  • founder of modern eugenics
  • wanted to show heredity of intelligences -> basis for intelligence tests

Q

Lamarck (1744-1829)

A
  • organisms acquire new characteristics as a result of active adaptation to their environment
  • minimized role of selection
  • new variations come to existence because organism are ACTIVELY and PURPOSEFULLY striving to better themselves
  • > then pass characteristics down to next generation

-theory of use and disuse

17
Q

Herbert Spencer (1820-) not complete yet!

A

-Neo-Lamarckian
-prefers theory of Lamarck
- survival of the fittest -> Darwin borrowed this term
-

18
Q

Jenkins Dilution problem

A
  • when organism with new feature is placed among group
  • > new feature will not expand but dilute in pool of preexisting features

Darwins response:
->evolution only possible when change in environment favores a whole group at the same time

19
Q

James McKeen Castell (1860-1944)

A
  • American psychologist
  • first professor of psychology in the US
  • psychology was regarded as lessers science/pseudoscience
  • helped establishing psychology as a legitimate science
  • visited Germany, met Wilhelm Wundt -> assistant of him
  • role in introducing experimental technique and importance of methodology in America
  • research on intelligence
  • founded several major psychology journals
20
Q

James McKeen Cattell - Connection Darwin

A
  • believed in eugenics
  • inspired by Darwin to study the psychology of individual differences
  • he encountered that men of science were likely to have fathers who were clergymen or professors
  • inherited ability but environment also plays an important role in development
21
Q

Thomas Malthus

A
  • inspired Darwin
  • food increases linearly
  • population exponentially
  • > more children than can survive -> selection
