Jan 3, 2024 · Human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits ...

Evo 101. The history of life: looking at the patterns. The central ideas of evolution are that life has a history — it has changed over time — and that different species share common ancestors. Here, you can explore how evolutionary change and evolutionary relationships are represented in “family trees,” how these trees are constructed ...
Darwin's explanation for this great unfolding of life through time—the theory of evolution by natural selection —transformed our understanding of the living world, much as the ideas of Galileo, Newton, and Einstein revolutionized our understanding of the physical universe. Darwin's theory of evolution by natural selection underlies all ...
Biology - Evolution, Genetics, Species: In his theory of natural selection, which is discussed in greater detail later, Charles Darwin suggested that “survival of the fittest” was the basis for organic evolution (the change of living things with time). Evolution itself is a biological phenomenon common to all living things, even though it has led to their differences. Evidence to support ...
