Was evolution around before natural selection?
The concept of evolution existed before the theory of natural selection. Evolution as a concept dates back to ancient Greek philosophers, while natural selection was proposed by Charles Darwin in the 19th century as a mechanism to explain how evolution occurs.
Why do people look for fossils?
People look for fossils to study and understand the Earth's history, evolution of species, and environmental changes over time. Fossils provide valuable information about life forms that existed millions of years ago and help scientists piece together the puzzle of life on our planet.
How did the idea of evolution become the modern theory of Darwinism?
The idea of evolution existed before Charles Darwin, but his work on natural selection and adaptation provided a comprehensive explanation for how it occurs. Darwin's "On the Origin of Species" presented evidence and a mechanism for how species change over time, leading to the development of the modern theory of evolution. Subsequent research and discoveries have only further supported and expanded on Darwin's original ideas.
Why are geology and paleontology index fossils?
Geology and paleontology use index fossils as key indicators for dating and correlating the age of rock layers. These fossils come from organisms that were widespread, existed for a relatively short geological time, and are easily identifiable. Their presence in different locations allows geologists and paleontologists to establish the relative ages of the rock strata and the environmental conditions of the past. This makes index fossils essential for understanding the Earth's history and the evolution of life.
Is ammonites good index fossels?
Yes, ammonites are good index fossils because they had a wide geographical distribution and existed for a long period of time. Their evolution is well-documented, making them useful for relative dating of rock layers.
Are Florida's Everglades classified as a national park?
Florida's Everglades are classified as a national park, so in other words yes it is!

Is an Oarfish related to a dragon?
That depends on whether or not you believe dragons existed. And whether or not you believe in evolution.
What theory states that most of Earth's current species developed from distinctly different species which existed earlier in time?
biological evolution ...........studyisland
What does the theory of evolution believe?
Evolution believes nothing. It assumes a couple of things, e.g. that life existed previously to any evolution occurring and that laws of physics and chemistry have been constant, etc.However, beyond these assumptions - which are valid - the theory of evolution relies on evidence and facts, and a lot of it.
What civilizations existed in pre-columbian America what were their origins?
The civilizations the existed in pre-columbian America were the Native American Indians. Their origins were immense continents with extraordinary climatic and environmental diversity.

How does analogous structure support evolution?
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
The evolution of the camel can be traced back at least 56 million years - Estimate the percent of this time that the modern camel has existed?
40%
True or false the theory of evolution focuses on the evolution of the human species?
False. Evolution is a general theory relating to the change amongst species over time. It is not specific to any particular species, nor even to a group of species, but to all species that have ever existed, are existing and will ever exist.
