Evolution Flashcards
It is a system of chronological dating that relates geological strata (stratigraphy) to time. This is also known as the calendar of events in Earth history and is established using fossil forms that are present in rocks.
Geologic Time Scale (GTS)
This system is the largest division that spans one billion years.
Eon
This system spans tens to hundreds of millions of years and is distinguished by extinction events and appearance of new life forms.
Era
This system spans no more than one hundred million years and is characterized by a single type of rock system.
Period
Earth’s formation happened
Hadean
This system is the smallest division characterized by distinctive organisms.
Epoch
The first life-forms appeared (such as the cyanobacteria)
Archean
The first multicellular organisms appeared
Proterozoic
The first chordates emerged
Paleozoic
The big reptiles proliferated
Mesozoic
What theory of evolution is based on inheritance of acquired characteristics?
Lamarck’s Theory/Lamarckism
Who proposed the Lamarck’s Theory/Lamarckism and mentioned theory of use and disuse?
Jean Baptiste-Lamarck
What theory of evolution is based on natural selection? The idea revolves around the survival of the fittest.
Darwin-Wallace’s Theory
The study of fossil remains.
Paleontology
Similar organisms can be found from countries which are believed to be near each other before the continental drift happened therefore suggesting similar ancestry.
