that species today look different from their ancestors
Common descent in biology is the idea that all living organisms share a common ancestor. This theory explains the evolutionary relationships between different species by suggesting that all organisms have evolved from a single common ancestor over time, leading to the diversity of life we see today. By studying similarities in DNA, anatomy, and other characteristics, scientists can trace the evolutionary history of species and understand how they are related to each other through a process of descent with modification.
Descent with modification
Descent with modification
True. Fossils provide evidence of descent with modification by demonstrating how species have changed over time through the fossil record. Transitional fossils show characteristics that are intermediate between different groups, illustrating the gradual changes that occur within lineages. This evidence supports the theory of evolution by showing the relationships between ancient and modern species.
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.
Modification:p hope this helped
Darwin studied modern organisms to understand how they descended from common ancestors and underwent modification over time through the process of evolution. He observed variations in traits among species and how these traits adapted to different environments, which contributed to their survival and reproduction. This concept of descent with modification emphasizes that species are not static but continually evolve, reflecting changes in both genetic variation and environmental pressures. Through his observations, Darwin laid the foundation for the theory of natural selection, illustrating how species adapt and diversify over generations.
A cladogram is a diagram used in biology to show evolutionary relationships between different species. It helps scientists understand how different species are related based on shared characteristics and can be used to study patterns of descent and common ancestry.
Descent with modification encapsulates the two key ideas central to the theory of evolution. These are that modifications (mutations) occur, and that these mutations are inheritable (passed on to descendants or offspring).
