Scientists use evidence from the fossil record, comparative anatomy, DNA analysis, and observations of natural selection to understand how organisms have changed over time. By studying these pieces of evidence, scientists can track the gradual changes in species over generations, providing strong support for the theory of evolution.
Scientists study fossils to learn about the history of life on Earth, past environments, and how different groups of organisms have evolved and changed over time. By analyzing fossil remains, scientists can reconstruct ancient ecosystems and understand how life has adapted to environmental changes over millions of years. This information helps us piece together the evolutionary timeline of life on Earth and how it has shaped the world we live in today.
Scientists can learn about evolution by examining the fossil record to track changes in species over time, studying the genetic material of organisms to understand their relationships and evolutionary history, and observing natural selection in action in populations over generations. By combining these different lines of evidence, scientists can develop a coherent understanding of how species have changed and diversified over millions of years.
Scientists use various lines of evidence, such as the fossil record, comparative anatomy, embryology, and genetics, to show that living things have changed over time. By studying these pieces of evidence, scientists can construct evolutionary relationships and track changes in species over generations. This accumulation of evidence supports the theory of evolution.
These scientists shared the idea that organisms change over time through the process of evolution. They believed that organisms are adapted to their environment through natural selection, a mechanism proposed by Charles Darwin.
To gain an understanding of how populations change over time, scientists often observe organisms with short generation times, such as fruit flies, bacteria, or certain plants. These organisms allow for quicker observation of changes in populations and genetic traits over multiple generations. By studying these organisms, scientists can infer how natural selection and other evolutionary forces shape populations over time.
Aside from fossils we can learn about organisms and how they have changed over the years by looking at the plants and animals we have today.
The classification system has changed over the years because a newly discovered organism may be very much like two groups of organisms biologists may disagree on which group to put the organism into.

There is no evidence that the heart has developed and changed as organisms have become more complex over time. Scientists do believe that the human heart is a product of evolution and has spent millions of years perfecting itself in order to keep humans alive.

Organisms on Earth have evolved and changed significantly over time.
To gain an understanding of how populations change over time, scientists often observe organisms with short generation times, such as fruit flies, bacteria, or certain plants. These organisms allow for quicker observation of changes in populations and genetic traits over multiple generations. By studying these organisms, scientists can infer how natural selection and other evolutionary forces shape populations over time.
it was developed by many scientists over many decades. *apex*
Scientists study a variety of evidence to understand the evolution of life on Earth, including fossil records, comparative anatomy, molecular biology, and biogeography. By examining how organisms have changed over time and how they are related to one another, scientists can piece together the evolutionary history of life on our planet.
