Question
Chapter 22, Problem 16TYU
Summary Introduction
To explain: Whether the idea that evolution in humans has gone from survival of the fittest to survival of almost everyone due to modern medicine and better sanitation is valid or not.
Concept introduction: Human beings are the first animals to undergo organic evolution, cultural and social evolution. Human beings are the highly advanced living organisms because they have greater intelligence and information transmission in the form of knowledge. They are the first animals to treat the diseases they are infected with.

Some scientists say that modern medicine and better sanitation are slowing down or altering the course of human evolution in highly developed countries today. As a result, evolution in humans today has gone from survival of the fittest to survival of almost everyone. Do you think that this idea is valid? Why or why not?
Natural selection allows certain species to survive. The organisms that survive are those best adapted to their environment. Does natural selection make organisms more complex and perfect?
In your body, you have systems (digestive system, circulatory system, etc.). Each system is made up of organs. Each organ is made up of tissues. Each tissue is made up of cells. Each cell is made up of chemicals. What characteristic of life is being demonstrated by all this?
Group of answer choices
development
natural selection
evolution
irritability
high complexity

EVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.

Evolution is based on which of the following concepts? (a) organisms share a common origin (b) over time, organisms have diverged from a common ancestor (c) an animals body parts can change over its lifetime, and these acquired changes are passed to the next generation (d) a and b (e) a, b, and c

Consider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.

Evolution by natural selection is founded on what basic idea?
Random genetic mutations that help a species survive will be more likely to be passed to future generations.
Only traits that will help an individual organism survive will be passed down to future generations.
Only the biggest, strongest, fastest, or smartest creatures survive.
Traits that animals acquire over their life will be taught to future generations.

Adaptation and Evolution
If you were to present that theme, which representative organisms would you use as example and why?
arrow_forward
The concepts of natural selection and evolution are central to how most biologists understand and interpret the world, and yet the theory of evolution is contrary to the beliefs of many religious groups. Why do you think this theory is so important to science and so strongly opposed by others? What evidence would be required to convince opponents of evolution?
arrow_forward
Which of the following statements about evolution is false?a. Gene mutations alone amount to evolution. b. Genetic drift and gene flow are modern theories of evolution.c. Natural selection contributes to evolution.d. Chimpanzees evolved from a hominoid ancestor.
arrow_forward
Evolutionary biologists often say that evolution “selects for outcomes” not for the particular genetic changes that lead to that adaptive outcome. Given that perspective, is it surprising that different gene mutations might be involved in the evolution of the same trait (such as light skin or adaptation to living in high mountains)? Why or why not?

Many crustaceans (for example, lobsters, shrimps, and crayfish) use their tails to swim, but crabs have reduced tails that curl under their shells and are not used in swimming. This condition is an example of what evidence of evolution? *

Natural selection

The concept of evolution has always been connected with some notion of progress–natural selection pushing populations toward better and better adaptations to create "perfect organisms." How would you argue that evolution does not craft perfect organisms?
