What evidence do you know of that supports the theory that life on Earth has evolved?
The theory of evolution is supported by instances of direct observation, the existence of homologies and fossils, and certain biogeographical patterns.
All life on Earth shares a single common ancestor, a new statistical analysis confirms. Because microorganisms of different species often swap genes, some scientists have proposed that multiple primordial life forms could have tossed their genetic material into life’s mix, creating a web, rather than a tree of life.
What have we learned from fossil evidence about evolution?
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
How have fossils provide evidence for evolution?
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
What is paleontological evidence?
Paleontological resources, or fossils, are any evidence of past life preserved in geologic context. They are a tangible connection to life, landscapes, and climates of the past. They show us how life, landscapes, and climate have changed over time and how living things responded to those changes.
What are fossils and palaeontological evidence?
Answer: Fossilization is a rare process that sometimes takes a million years to be formed. And the fossils are the traces of prehistoric organisms which are palaeontological evidence that provides data about the evolution of life on Earth.
