When organisms try to blend into their environment in order to help them survive.
What is camouflage.
100
The change over time; the process by which modern organisms have decsended from ancient organisms.
What is evolution.
100
Organisms that have traits with the same function, but different structure. Ex: A bird's wing and a bat's wing.
What is an Analogous structure.
100
He proposed that slow-acting geological forces shape the planet. Earth is millions, not thousands of years old.
Who is James Hutton.
100
Nature provides the variations, and humans select those they find useful. Ex: Dog Breeders.
What is Artificial Selection.
200
The father of Evolution.....He proposed the theory of natural selection.
Who is Charles Darwin.
200
The study of where organisms live now and where they and their ancestors lived in the past.
What is biogeography.
200
Process by which unrelated organisms independantly evolve similarities when adapting to similar environments. They were different species, but the same species. Ex: Ostrich, Rhea, and Emu.
What is convergent evolution.
200
In his essay on the "Principle of Population", he predicts that left unchecked, the human population will grow beyond the space and food needed to susutain it.
Who is Thomas Malthus.
200
This is the driving force of variation in a species.
What is random DNA mutations.
300
This is a structure that is inherited from ancestors but has lost much or all of its original function.
What is a vestigial structure.
300
The process by which organisms that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest.
What is natural selection.
300
The process by which a single species or a small group of species evolves over a relatively short time into several different forms that live in different ways. They were the same, but then become different. Ex: Darwin's finches & Giant Tortoises.
What is Divergent evolution or Adaptive Radiation.
300
He proposed the theory of the inheritance of acquired traits.
Who is Jean-Baptiste Lamarck.
300
What is the name of the Islands that Dawin found his finches?
What is the Galapogos Islands.
400
When a species takes on the characteristics of another species that has a desirable trait for survival.
What is mimicry.
400
Heritable characteristic that increases an organism's ability to survive and reproduce in an environment.
What is an adaptation.
400
How well an organism can survive and reproduce in its environment.
What is Fitness.
400
In his "Principles of Geology", he explains that over long periods, the same processes affecting Earth today have shaped Earth's ancient geological features.
Who is Charles Lyell.
400
What was Darwin's father's profession?
What is a physician.
500
Preserved remains or traces of ancient organisms.
What is fossils.
500
Organisms that have traits with the same structure but different funcitons. Ex: Human arm and whale fin.
What is a homologous structure.
500
A group of similar organisms that can breed and produce fertile offspring.
What is a species.
500
He speculates on evolution by natural selection, based on his studies of the distribution of plants and animals.
