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 fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading
B.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.
C.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.
D.The technology for extracting DNA from fossils hasn't been developed yet
Modern dogs are direct descendants of the gray
wolf. They first appeared about 130,000 years
ago. Today, there are about 150 different breeds of
domestic dog, a few of which are shown below.
1.
Gray wolf
All modern domestic dogs are descendants of the gray wolf.
adapted from: www. pba.org
The great variety of modern dogs can best be
explained by
A. selective breeding of dogs over many years
B. the cloning of domestic dogs
C. genetic alterations in gray wolves alive today
D. natural selection favoring wolves over dogs
You are reading a scientific paper regarding the relationships of the anatomical and behavioral characteristics of chimpanzees and their implications for early hominid evolution. With the emphasis on anatomical and behavioral characteristics, this implies that the researchers are relying on
A. Traditional classifications of chimpanzees and humans

C. An incorrect classification of human ancestors
D. Cladistic classifications of chimpanzees and humans

- Most scientists consider the Human Genome Project (HGP) to be the most significant scientific project of the 21st century. Choose the statements that describe the key findings of the Human Genome Project. A. There are 23 pairs of chromosomes that make up the human genome. B. DNA exists in a double helical form. C. There are approximately three billion base pairs in the human genome. D. The human genome contains approximately 25000 genes. E. The genetic information of a cell is stored in the form of DNA.arrow_forwardScientists conducted research to examine the evolutionary relationship between 10 bird species and an alligator species.
