The theory that different organisms have ancestors that are related is the ?
This theory is known as the theory of evolution, which states that living organisms have descended and diversified over time from common ancestors through the process of natural selection and genetic mutation.
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.
Comparing embryos of different organisms can reveal similarities in their development, suggesting a common ancestry. These similarities in early development provide evidence for evolution by showing that different species share a common evolutionary history. Studying embryonic development can help trace the evolutionary relationships between different species and support the idea of descent with modification.
The theory of evolution is supported by evidence such as the similarities in DNA and physical traits among different species that share common ancestors. This suggests that animals have evolved over time to adapt to different environments in order to survive and thrive.
The single called ancestor theory is also known as the monogenism theory, which proposes that all humans are descended from a single pair of ancestors. This theory contrasts with the polygenism theory, which suggests that different groups of humans have separate origins.
True
Vestigial structures are remnants of organs or features that were functional in an organism's ancestors but have reduced or lost their original function over time. The presence of these structures suggests that present-day organisms have undergone evolutionary changes from their ancient ancestors. These structures provide evidence for common ancestry and support the theory of evolution.

According to the theory of evolution, our earliest ancestors were not much different than apes. These early ancestors practiced polygamy and had love duels for their potential mates.

Convergent evolution, or convergence theory.
The cell theory applies to all organisms.
The single called ancestor theory is also known as the monogenism theory, which proposes that all humans are descended from a single pair of ancestors. This theory contrasts with the polygenism theory, which suggests that different groups of humans have separate origins.
line of descent
Evolution is the process by which organisms change over time through genetic mutations and natural selection. It connects all life by showing how different species are related through common ancestors. Over millions of years, gradual changes and adaptations have led to the diversity of life forms we see today.
