What change occurred in the shape of the horse from hyracotherium to equus?
What changes occurred in the size of the horse from Hyracotherium to Equus? 5. Describe the overall changes in foot length, number of toes, and size of toes in the horse over time. that had them these horses would have had a greater chance of surviving that horses not adapted.
How did the knowledge of evolution affect the way organisms are classified?
The older morphological methods were, in many cases, shown to be wrong because there was no real evolutionary connection. And in other instances the evolutionary connection was shown for organisms that were morphologically quite dissimilar.
Which is not a cause of evolutionary changes in organism?
evolutionary changes in organisms
What are the raw material of evolutionary change?
Mutations are considered as the raw materials of evolutionary change. They are structural changes in the DNA sequence of an organism.
What is a transitional organism?
A transitional organism is a fossil species that exhibits characteristics of both ancestral and derived groups, providing evidence of evolutionary transitions between major groups of organisms. These transitional fossils help to illustrate the gradual changes that occurred over time, supporting the theory of evolution.
What problem does chromosome number of various organisms present to evolutionists?
The variation in chromosome number among species can make it challenging for evolutionists to understand how these changes occurred over time. It can also complicate the process of studying the evolutionary relationships between different species. Additionally, changes in chromosome number can affect an organism's fertility and reproductive success, which can impact its evolutionary trajectory.
What evidence do biologists use to establish evolutionary traits?
They use the physical changes in physical Form of an Organism, that naturally occur over Time, to do this.
What answer is an accurate description of the changes in educational attainment in the four regions?
Growth in educational attainment occurred in all regions in the 1990s.
When changes occur in the genes of sex cells these changes... a lead to mutations in the parent organism b are always harmful to the offspring c can be the basis for evolutionary change and 4?
Can be the basis for evolutionary change. When changes occur in the genes of sex cells, these changes can be passed on to offspring and may result in beneficial adaptations over generations, leading to evolutionary change.
What is a evolutionary path?
An evolutionary path refers to the series of changes and adaptations that an organism undergoes over time as it evolves to better suit its environment. This includes genetic mutations and natural selection that drive the development of new traits and species.

Can an organism inherit a virus from a parent?
Yes, but only retroviruses capable of incorporating into the DNA of chromosomes and the virus infected reproductive cells. It is now thought by some evolutionary biologists that such viruses may facilitate inter-species genetic transfers that triggered some of the significant evolutionary changes.
