Key Points of Darwinism
True or False: All individuals in a species are exactly the same.
False, there is variation in a single species too.
What is natural selection?
The process where the ones that do not fit to an environment gets eliminated and the ones that do fit keeps living on.
What is an adaptation?
A characteristic that helps an organism survive and reproduce in its environment.
What does survival depend on based on Darwinism's 5 main key points.
It depends on the ability to compete for food and resources.
It is more likely to survive and pass on its ability to offspring
What type of adaptation helps an animal blend into its surroundings to hide from predators?
Camouflage
According to Darwin's 5 key points, what changes over time due to natural selection?
Populations
True or False: Organisms who survive less and don't reproduce as much are the ones with favorable traits.
False. They are the ones with unfavorable traits.
A clearwing moth looks like a wasp so predators avoid it. What type of adaptation is this?
Mimicry
Why do many offspring die before reaching adulthood?
Competition for food, light, water, predators, and parasites.
In a jungle, which one will have a bigger probability to be selected: A green butterfly or a red butterfly.
Green butterfly. It will have a bigger probability at surviving because of its color.
What is the difference between camouflage and mimicry?
Camouflage blends into the environment while Mimicry blends into a dangerous or unpleasant organism.
Why having MORE offspring than can survive is actually necessary for natural selection to work.
Because if all offspring survived, there would be no competition, no struggle, and no "selection".
"That lion got stronger because it needed to survive." Why is this statement wrong according to Darwin?
Darwin says individuals don't change. The lion was already born stronger due to variation. Natural selection cannot change that single lion.
A harmless cockroach evolves to look like a dangerous ladybug beetle.
1. What is the name of this adaptation.
2. What is the reason of this adaptation.
3. What is the way that this adaptation happened.
1. Mimicry
2. To scare off predators and survive.
3. The cockroaches who looks like ladybug beetles because of variation got selected.
