Darwin & The Beagle
The famous book written by Charles Darwin.
What is "On the Origin of Species by Means of Natural Selection"?
The process where better-equipped competitors survive and less-equipped ones die
What is natural selection?
This source of information is used to determine the ancestry of organisms and patterns of evolution.
What is the Fossil Record?
Structures inherited from a common ancestor.
What are homologous structures?
A trait shaped by natural selection that increases reproductive success.
What is an Adaptation?
The role Darwin served while traveling on the HMS Beagle.
What is a Naturalist?
This principle states that more offspring are born than can actually survive.
What is one of the Principles of Natural Selection?
Newly evolved features, like feathers, that do not appear in common ancestors.
What are derived traits?
Structures that are reduced in size and no longer have a function, such as human wisdom teeth.
What are vestigial structures?
An adaptation that allows an organism to blend into its surroundings.
What is camouflage?
Darwin noticed that each of these islands had unique species similar to those on the main island.
What are the Galapagos Islands?
Traits that increase this will become more common in the next generation.
What is reproductive success?
Primitive features, such as teeth or tails, that do appear in ancestral forms
What are ancestral traits?
Structures used for the same purpose and superficially similar but NOT inherited from a common ancestor.
What are analogous structures?
A measure of the relative contribution an individual trait makes to the next generation.
What is fitness?
This process involves directed breeding to produce offspring with desired traits.
What is Artificial Selection?
The relationship between natural selection and evolution.
What is "Natural selection is a mechanism/cause of evolution"?
The study of the distribution of plants and animals around the world.
What is Biogeography?
This field shows that vertebrate embryos exhibit homologous structures during development.
What is Comparative Embryology?
An adaptation where one species evolves to resemble another species.
What is mimicry?
Darwin’s hypothesis regarding how new species could develop over time.
What is "from small, gradual changes"?
This occurs when variations are passed down from one generation to the next.
What is Variation/Inheritance?
Evolution is linked to these three global forces.
What are migration patterns, climate, and geological forces?
This field posits that more closely related species have greater biochemical similarities.
What is Comparative Molecular Biology?
The primary driver that shapes adaptations in a population.
What is natural selection?
