1) DNA molecules

To get a better understanding of how plants and animals evolved from a common ancestor, scientists can analyze various pieces of evidence. Here are the options provided and how each one can contribute to our understanding:

1) DNA molecules: Scientists can analyze the DNA of different species to identify similarities and differences in their genetic makeup. By comparing DNA sequences, they can determine the degree of relatedness between different organisms and construct evolutionary relationships based on shared genetic traits.

2) Vertebrate embryos: By studying the development of embryos in different species, scientists can identify similarities in the early stages of development. These shared features suggest a common ancestry and provide insight into how different species have evolved over time.

3) Petrified bones and imprints of plants: Fossils, such as petrified bones and imprints of plants, offer a direct glimpse into past life forms. By examining these preserved remains, scientists can trace the evolutionary history of both plants and animals, documenting changes in their anatomy and morphology over millions of years.

4) Life cycles and behaviors: Analyzing the life cycles and behaviors of various organisms can also provide valuable information about their evolutionary relationships. By studying how different species reproduce, grow, and interact with their environments, scientists can identify evolutionary patterns and infer common ancestry.

In summary, scientists can use all of these methods – analyzing DNA molecules, studying vertebrate embryos, examining fossils, and observing life cycles and behaviors – to gain a better understanding of how plants and animals evolved from a common ancestor.
