What else can I help you with?
What is it called when newer generations are better suited to an environment than the first generation is?
descent with modification
What three word phrase summarizes Darwin's mechanism of evolution?
Darwin used the phrase "descent with modification" (he didn't use the term "evolution")
What phrase did Darwin use instead of evolution?
Darwin used the phrase "descent with modification" in his book "On the Origin of Species" instead of the word "evolution." He used this phrase to describe the process by which species change over time through natural selection.
What provides physical evidence of descent with modification over long periods of time?
Homologous Structures
Charles Darwin's idea of how species change over time is called what?
Charles Darwin's idea of how species change over time is called natural selection. This process involves the survival and reproduction of organisms that are best adapted to their environment, leading to gradual changes in the characteristics of a population.
What is the concept that each living species has descended with changes from other species over time referred?
Descent with modification
What is the concept that each living species has descended with changes from other species over time referred as?
Descent with modification
What principle states that living things change gradually over time through natural selection?
The theory of evolution by natural selection.
Is population increase is species change over time descent with modification?
Depends if the population increase is related to a selected pressure, you could then argue that the population change is an extended phenotype.Typically population fluctuations are NOT considered decent with modification and are seen as random drifts with out any selective pressures working on them.Good question,
What does Darwin's theory of descent with modification mean?
Darwin's theory of descent with modification, also known as evolution by natural selection, proposes that species evolve over time through the process of variation and differential survival and reproduction. This means that species descend from common ancestors and accumulate changes or modifications that help them adapt to their environment.
How does DNA support Darwin's theory of descent with modification?
DNA contains the genetic information that determines an organism's traits. Through mutations and genetic variations, DNA can change over time, leading to differences in traits among individuals within a population. This supports Darwin's theory of descent with modification, as it provides a mechanism for how species can evolve and adapt to their environment over generations.
Which two ideas did Darwin use to explain evoultion?
Darwin used the ideas of natural selection and descent with modification to explain evolution. Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce, passing those traits on to their offspring. Descent with modification refers to how species change over time through the accumulation of small changes in their inherited traits.
