These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.
Answer = Natural Selection
Comparing organisms can show similarities in their DNA, anatomical structures, and developmental processes. These similarities suggest that the organisms share a common ancestor and have evolved from it through the process of descent with modification. By studying these similarities, scientists can trace the evolutionary history of different species and understand how they are related through common ancestry.

That's correct! The theory of evolution states that organisms have evolved over time from common ancestors through the process of natural selection. This gradual change in species over generations is driven by factors such as genetic variation and environmental pressures.

Colonial organisms likely evolved into multicellular organisms through a process known as cellular differentiation, where specialized cells with specific functions developed within the colony. This evolutionary transition allowed for increased complexity and efficiency in tasks such as reproduction, growth, and survival.
Plants, algae, and some bacteria are organisms that go through the process of photosynthesis.
All organisms, including humans, have evolved from ancestral organisms and continue to evolve, although at a rate too slow to witness during one lifetime.
Darwin said that organisms evolve through the process of natural selection.
The theory that states organisms evolved from a common ancestor is the theory of evolution proposed by Charles Darwin in his book "On the Origin of Species" published in 1859. Darwin's theory of evolution by natural selection explains how species change over time through the process of adaptation to their environments.
Vestigial structures are remnants of organs or traits that were functional in ancestral species but are reduced or non-functional in present-day organisms. These structures provide evidence of evolution because they suggest that organisms have evolved from ancestors with different adaptations, and over time, structures that are no longer useful have become reduced or lost. This supports the idea that organisms have changed over time to adapt to their environment through the process of evolution.
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.
