100
His theory of use and disuse of body parts and the inheritance of acquired traits was the first to suggest change over time.
Who is Jean Baptiste Lamarck
100
When a generation produces more offspring than can survive.
What is overpopulation
100
The fossil record provides a connection between organisms that lived in the past and those living in the present. That connection can be observed in ____________ species that shares characteristics of past and present organisms.
What are transitional species.
100
Change in one organism selects for change in a closely associated organism. An example would be the hummingbird and the red cardinal flower.
What is coevolution
100
This must be present in a population for evolution by natural selection to occur.
What is variation
200
In a letter, he told Darwin of the observations of change in organisms over time he had made while working in Africa. This prompted Darwin to publish his work in a book "On The Origin of Species by Natural Selection."
Who is Alfred Wallace
200
Living organisms compete for limited resources. The ability of an organism to compete and survive in its environment is called
What is fitness
200
Remnant structures such as the pelvic bones of whales that served a purpose in a common ancestor but no longer serve a purpose.
What is a vestigial structure
200
A pattern of divergent evolution that can be observed in the speciation of the Galapagos finches.
What is adaptive radiation.
200
Another term for Natural Selection.
What is Descent with Modification
300
He observed the rate of growth of the human population and suggested that overpopulation ultimately leads to competition for limited resources. He also suggested that three things keep populations in check and they are ________, _________ and ___________.
Who is Thomas Malthus and what are war, famine and disease
300
The selective pressures of the environment favor organisms that are more fit and select against organisms that are less fit.
What is Natural Selection
300
Similar in structure due to similar common ancestry but not similar in function. An example would be the forelimb of vertebrates.
What are homologous structures.
300
A pattern of little to no change followed by periods of rapid change as witnessed in the evolution of horses.
What is punctuated equilibrium
300
The famous voyage aboard the ________ provided Darwin an opportunity to make many observations of species in their environment with the most influential of those stops being ___________________.
What is the HMS Beagle that stopped at the Galapagos Islands
400
The process of human selection of favorable traits to be passed onto offspring prompted Darwin to hypothesize that nature could select favorable traits as well. The process of humans breeding animals or cultivating crops is called
What is Artificial Selection
400
Organisms with greater fitness survive in their environment and pass their favorable traits onto their offspring.
What is reproduction
400
Developmental similarities in animals such as the presence of a tail and pharyngeal pouches provides evidence for a close common ancestor
What is embryology
400
When selective pressures of the environment no longer favor the survival of the remaining members of a species.
What is extinction.
400
An example of "Evolution in Action"
What is the English Peppered Moth
500
In his book, "Principles of Geology," he proposed the concept of uniformitarianism which states that the same geological forces that have changed Earths surface in the past continue to do so in the present. His colleague proposed that the slow progression of geological change on Earth took extremely long periods of time suggesting that the Earth is very old.
Who are Charles Lyell and James Hutton
500
Traits within a population change over time due to the selective pressures of the environment. OR Change over time can ultimately lead to the formation of new species.
What is microevolution and macroevolution
500
Highly conserved sequences of DNA or sequences of amino acid of proteins provides evidence for organisms that share common ancestry.
What is biochemical evidence.
500
Similarities in the selective pressures of a similar environment lead to the evolution of similar body plans. This is observed in the dolphin, whale and penquin.
What is convergent evolution.
500
The distribution of plants and animals across the world provided Darwin with some of the strongest evidence for evolutionary change. For example He observed an absence of species from some environments that would favor their survival as well as the similarity between species that occupy similar environments.
What is biogeography
