Summary Introduction
To determine:
The evidence that support the evolutionary relationship of birds and dinosaurs. The way in which scientists can use the sequence of
Introduction:
All organisms evolve from some primitive organisms. The study of ancestor’s organisms and their descendants on a large scale is termed as evolution. A new organism arises from an older one, and it adapts new characteristics to become different from its forefather. Birds and dinosaurs have also evolved from other organisms.

Developmental Biology - Embryology
Many scientists use what an organism looks like as an
embryo, or embryology, as evidence for evolution. The
embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar.
What does the study of embryology show when comparing most vertebrates?
According to "Our Earliest Ancestors", why can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to?
A.The technology for extracting DNA from fossils hasn't been developed yet.
B.Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material.
C.The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading
D.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.
Use the information and diagram to answer the following question.
In humans, the pelvis and femur are involved in walking. Despite the fact modern whales live in water, they contain a pelvis and femur that are common in land dwelling animals.
Based on your observation of the whale diagram and your understanding of evidence that supports evolution, what is TRUE about the pelvis and femur found in living whales today?
A.
They are newly developed structures found in modern whales due to mutations.
B.
They are examples of fossilized remains of ancient organisms.
C.
They are traits acquired by modern whales over time as they adapted to living in water.
D.
They are vestigial structures which are remnants of structures that served a function in the organism’s ancestors.
