Who studied earthworms?
Why do scientists care about worms?
But really, many worm species provide opportunities for scientists to perform basic research on cells and systems that can be translated into information about our biological origins, and even relevant applications for human development and health.
What did Charles Darwin discover about earthworms?
By doing experiments in his yard, Darwin proved that earthworms were turning the soil and making it more fertile. This was a surprising finding to 19th-century gardeners, who thought the worms were pests.
Which worm babies have more favorable traits or characteristics and will eventually evolve?
c) the nocturnal worms have more favourable traits and characteristics and will eventually evolve.
What are the 4 causes of evolution?
Describe the four basic causes of evolution: natural selection, mutation, genetic drift, and gene flow.
What are the 4 components of natural selection?
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Why are advantageous traits passed onto offspring?
Variations of traits causes those better suited to the environment to survive and reproduce. Why are advantageous traits more likely to be passed onto offspring? Because they are more likely to survive and reproduce. Because they come from dominant alleles.
What increases the chance that a trait will be passed onto offspring?
Answer: Inherited traits are influenced by genes, which are passed on to offspring and future generations. Natural selection means that traits that offer an advantage will most likely be passed on to offspring; individuals with those traits have a better chance of surviving. Evolution occurs by natural selection.
What is it called when an organism completely dies?
when an organism completely dies out it is called extinct.
Which trait Cannot be inherited?
Scarred eyebrow is an acquired trait which is never passed on to the offspring because scarring does not change the genes of the reproductive cells of the parent.
Is character inherited?
Character, in biology, any observable feature, or trait, of an organism, whether acquired or inherited. An acquired character is a response to the environment; an inherited character is produced by genes transmitted from parent to offspring (their expressions are often modified by environmental conditions).
