evolution
credited with the theory of evolution
who was Charles Darwin?
He came up with the idea of this mechanism of evolution
who was Alfred Wallace?
Science has discovered 1.3 million organisms so far and estimate that there are
what is 8.7 million species in total
The definition of life
what is the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death?
the definition of variations
what is Every organism is different from every other organism within a species- with a few exceptions. Every organism's genes are different, too?
The simple meaning of "evolution"
What is "change over time"?
natural selection is caused by
what is 'natural variations among individuals'?
the definition of biodiversity
what is The number of species of plants, animals, fungi, and microorganisms, the enormous diversity of genes in theses species, the different ecosystems on the planet, such as deserts, rainforests, and coral reefs are all part of a biologically diverse Earth?
the characteristics of life
What are cellular, response to the environment, reproduction, metabolism, homeostasis, heredity, growth and development, adaptation
What are clones?
The formal definition of Evolution
What is a gradual process where part of an animal changes to be better suited for the environment?
This method uses natural variations that are found in other species to be desirable by humans and manipulates them to be selected by us (different from natural selection)
what is "artificial selection"
ways to measure biodiversity
What are species richness (number), genetic diversity, endemic species, ecosystem diversity, unique ecosystems?
the first form of life
what is single cells?
when variation becomes an adaptation
what is a variation that gives an individual an advantage for survival?
the mechanism that drives/causes evolution
What is 'natural selection'?
Natural selection is based on two struggles
What is the struggle to existence and the struggle of the fittest?
the way Namib desert beetle gets water
What is collects morning dew droplets from fog and lifts its rear end and lets it roll down it's back into it's mouth?
the building blocks (molecules) of life
what are amino acids which make proteins?
these can be harmful, helpful, or beneficial and lead to an adaptation
What are mutations?
Darwin said it is not necessarily the strongest or most intelligent organisms that survive but
what is 'the ones who can respond to change'?
natural selection definition
What is Individuals best suited for the environment survive and reproduce most successful?
how zebras avoid getting eaten by lions
What is the adaptation of black and white stripes which creates visual confusion when the herd runs close together?
when first life on earth came into existence
what is about 4.2 billion years ago?
the different types of adaptations
What are behavioral, physical, or physiological?
