What states that traits an organism develops during its own life time can be passed on to offspring?
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
When an organism reproduces it passes on its own traits to its offspring?
pass traits to their offspring. Organisms can reproduce by asexual reproduction. In asexual reproduction, only one parent makes offspring. The parent makes a copy of itself through mitosis.
What concepts states that having many offspring increases the chance that some of them will survive?
The two general ideas of Darwin’s Theory are evolution and natural selection. The concept of natural selection includes these observations and conclusions: By chance, heritable variations exist within a species. Species produce more offspring than can survive.
What was Lamarck’s theory called?
Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin’s first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring.
Who suggested that acquired traits can be inherited?
Two centuries ago, Lamarck, a French biologist proposed that the characteristics acquired during an organism’s life could be passed on to subsequent generations.
Why do organisms produce more offspring than what can survive?
1. Organisms produce more offspring than actually survive. One reason that not all organisms survive is that there are not enough resources, things that they need, to go around. Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.
How are inherited traits passed on to offspring?
Lyell argued that gradual geological processes have gradually shaped Earth’s surface inheritance of acquired characteristics states that traits an organism develops during its own life time can be passed on to offspring Wallace
How is Darwin’s Theory of evolution passed on?

How is evolution a change in species over time?
Natural selection a change in a species over time. nature selects the variations within a species that are most useful for survival. fitness is an organism’s ability to survive and produce fertile offspring. evolution a change in species over time
Who was the first scientist to propose that species change over time?
Argued that human populations grow faster than the resources that they depend on. Jean Baptiste Lamarck One of the first scientists to propose that species change over time. Natural selection
