Describe three lines of evidence that support the theory of evolution Provide an example for each line of evidence you list?
Fossil Record the ordered array in which fossils appear within layers of sedimentary rocks. Comparative Anatomy comparison of body structures in different species, which give signs of common descent. Biogeography the geographical distribution of species.
Why does scientific evidence support scientific theories?
use scientific evidence to support your answer
What evidence can support that organisms have changed over many generations?
Fossil records are the most common way besides actually documenting members of a species generation by generation.
Why is evolution such a robust theory?
Because there are huge ammounts of evidence to support the theory.Fossils, DNA and carbon-dating allow us to make huge assumptions and relations between species.
What are the 4 broad categories of evidence used to support evolution?
The fossil record, computational genomics, vestigial genes/structures, biogeographical distribution of species, comparative anatomy, and direct observation
How does the idea of a common ancestor help support the theory of evolution?
The concept of a common ancestor in evolution suggests that all life on Earth shares a common origin, providing a framework to explain the diversity of species through gradual changes over time. It supports the theory of evolution by showcasing the interrelatedness of all organisms and the branching patterns of descent that have led to the vast array of species we observe today. By tracing back to a common ancestor, scientists can understand the evolutionary relationships among different species and how they have diverged and adapted over time.
Are genes different between species and individuals?
Yes, both. Genes are increasingly different between species that are farther apart on the evolutionary tree. Humans and chimpanzees share roughly 99% of their DNA, evidence to support the theory that humans and chimps have a relatively recent common ancestor. Individuals of the same species share almost all the same genes (putting aside the X and Y chromosomes that separate male and female). Only small variations result in the small variations you see: face, height, hair color, skin color, etc.

How does comparative anatomy support then idea that organisms share ancestors?
Comparative anatomy does not prove evolution itself, but is strong evidence because it shows that animals and species do change through periods of time; if evolution were not so, there would be no comparison possible since they would either be exactly the same or they would be different species.
What argument did Darwin support about the beak size and shape of Galapagos finch species and its relationship with something else?
Darwin used the wide variation of beaks to support his theory of evolution. He speculated that all the different finches had descended from one species and were not different species.
What does corroborate mean?
Corroborate means to strengthen or support with evidence.
How does the existence of different varieties of species support the concept of evolution?
It doesn't. It supports creation.
How do to submit evidence for Child Support?
The judge will let you know what documentation is required for a child support order to be established. Every case is different.

Why were Darwin's publications on the origin of species controversial?
Darwin presented exstensive evidence from many areas of biology to support his ideas
What led scientists to believe that Homo erectus was the nearest ancestor to humans?
Scientists believe Homo erectus is a likely ancestor of humans because of its physical similarities to modern humans, such as upright posture and increased brain size compared to earlier hominins. Additionally, Homo erectus is thought to have used more advanced tools and had a more complex social structure than earlier species, suggesting a closer relationship to modern humans. Fossil evidence, such as those found in Africa and Asia, also support the idea that Homo erectus is a key transitional species in human evolution.
What whale only has one mate?
None. Whales don't practice monogamy. In the past, it was thought that they did but recent genetic testing has shown both male and female whales may have a multitude of different mates. This is true for all species of whale. There have been claims by some activist groups that some whale species mate for life, but there is no evidence to support this. Whereas there is plenty of real evidence to say otherwise. They generally argue this to "humanize" the species and to lobby support for their cause. While their hearts are in the right place, they are factually wrong. True monogamy is actually rare in the animal kingdom.
