fossils
The theory Charles Lyell was credited with states that the geologic processes thats helped shape Earth in the past continue to operate today?
uniformitatianism
Similar bone structures in the limbs of humans, whales, and bats are examples of these.
homologous structures
When similar traits evolve in unrelated species due to similar environments, it’s called this.
convergent

Determining the age of a fossil by comparing it to other fossils in the different rock strata is known as the fossils

acquired traits/characteristics
The random part of evolution is commonly referred to as a....
mutation
Darwin’s theory suggests that all species descend from these.
common ancestors
According to Darwins theory of natural selection, organisms that have more favorable traits tend to what....
Have more offspring/greater fitness
The process where humans select organisms with desirable traits to reproduce is called this.
artificial selection
According to Darwin, this provides the raw material for natural selection.
