- Raised a lot of questions
Term
Lamarck
Definition
-1800's
-Best explaination for fossils was that things changed enough over time until people can not recognize them anymore

Inheritance of acquired characteristics

-How things change
-People started to investigate other places like Africa and so they saw things that had never seen before like giraffes
-Fueled competitions in cities to make the best zoos
-Giraffes got their long necks from stretching to reach leaves and passed it on the future generations
-Lamarck was wrong but he was headed in the right direction; first to say that things change
Term
Charles Darwin

_Found and collected tens of thousands of specimens that no one had ever seen (archetypes)
-Went to the Galapagos Islands off of ecuador
Term
Principles of Geology by Charles Lyell
Definition
-started to get the idea that things changed over time
-Thought that there had been enough time for things to have changed that much
-Lyell had proposed in the book that the earth could be millions of years old
-this gave darwin the things needed to finish his theory
Term
Alfred Wallace
Definition
-1850's
-Had been all over southeast asia
-Started to come up with his own idea that things changed over time (same time and idea as darwin)
-Met with darwin and shared ideas

Natural selection
Definition
-Mechanism for evolution; makes evolution work
-Differential reproduction
-
Term
Tenets proposed by darwin and wallace
Definition
-More offspring tend to be produced than can ever possibly survive
-Individuals/ offspring in a population show variation (bell curve)
-Some traits are more adaptive than others (give an advantage to the offspring)
Term
Adaptive traits
Definition
Will give a slightly better chance of survival
Term
Differential reproduction
Definition
-Result of natural selection
-Individual that passes most genes to the next generation wins
-Leaving more traits allows more offspring to have advantage to stay alive
Term
Survival of the fittest
Definition
-the most fit organism leaves the most offspring
-Other people (not darwin) coined this phrase
-British took this phrase to the extreme
Term
