What is the main concept of 'Survival of the Fittest'?

Back

It describes the theory of natural selection, where organisms better adapted to their environment tend to survive and produce more offspring.

What does evolution refer to in biological terms?

Back

Evolution is the process through which species change over time, often in response to environmental pressures.

Front

What are mutations?

Back

Mutations are changes in the DNA sequence of an organism's genome.

Front

How do finch beak shapes relate to evolution?

Back

Different beak shapes in finches are adaptations that allow them to access various food sources, demonstrating natural selection.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more species have evolved.

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce.

Front

What is the significance of DNA in evolution?

Back

DNA carries genetic information, and changes in DNA (mutations) can lead to variations that drive evolution.

Front

What role do environmental conditions play in evolution?

Back

Environmental conditions can influence which traits are favorable, affecting survival and reproduction.

Front

What is the relationship between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype is the observable characteristics resulting from the genotype.

Front

How can populations grow?

Back

Populations can grow when resources are abundant, leading to increased survival and reproduction.
