Adaptation
Structural adaptation is what?
Body parts
What is evolution?
Evolution is the process by which species change over time through inherited traits. These changes happen across many generations.
What are embryological similarities, and why are they important?
Embryological similarities are similarities in early development stages of different species. These similarities suggest that the species evolved from a common ancestor.
What is adaptation?
A change or the process of change by which an organism or species becomes better suited to its environment.
Why do species change over time?
Why do species change over time?
How does comparative anatomy provide evidence for evolution?
Comparative anatomy studies similarities and differences in body structures. Similar structures in different species suggest they share a common ancestor.
An example of adaption.
Camouflage, thick fur, sharp claws, long roots
How does natural selection lead to adaptation?
Natural selection increases the frequency of beneficial traits in a population. Over generations, these helpful traits become common, resulting in adaptations to the environment.
How does DNA support the theory of evolution?
When species have similar DNA, it shows they are closely related and likely share a common ancestor.
Behavior adaption is what?
actions
What are the four main mechanisms of evolution?
The four main mechanisms are natural selection, mutation, genetic drift, and gene flow. Each one changes the genetic makeup of a population over time.
What are fossils, and how do they support evolution?
Fossils are preserved remains or traces of ancient organisms. They show how species have changed over time and provide evidence of extinct species.
Physiological adaption is what?
The body process
How does mutation contribute to evolution?
Mutation introduces new genetic variations into a population. Without mutations, there would be no new traits for natural selection to act on.
