Why is it so difficult to
HIV resists treatment because of its rapid evolution
List some of the types of
evidence for evolution.
increasing complexity in fossils from older to younger, transition fossils, biogeography, molecular biology,comparative embryology, comparative anatomy
What are layers structures formed by bacteria in shallow water? These provide some of the most ancient records of life on Earth by fossil remains that date back over three billion years.
what type of variation was important to Darwin's theory?
What year did Darwin publish is seminal work on evolution?
What are organisms that show the characteristics of two distinct taxonomic groups?
Darwin's theory included the concept of competition. What is the cause of this competition?
the ability of organisms to reproduce more offspring that there are resources to support them
How does HIV resist treatment?
it rapidly evolves within a single patient
Feathered dinosaurs, archeoptrex, horses and their ancestors, and several species in the genus Homo, are all examples of what type of fossils that show the characteristics of the tow distinct taxonomic
The emergence of new species, changes in gene frequencies with a species, changes in the beaks of finches as the availability of various seeds change, and domestic selection are all examples of what?
direct observational evidence for evolution
HIV has what type of genetic material?
ribonucleic acid (RNA)
What are the main title of Darwin's book on evolution?
On the Origin of Species
What is the study of distribution of species and ecosystems through space and time? The science is one of the fields providing evidence for evolution.
What is a simple but useful definition of natural selection?
differential reproductive success
What is the scientific specialty that compares the biological structure of organisms and relates that structure to evolution?
