What is natural selection in evolution?
Natural selection is the process through which populations of living organisms adapt and change.
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
It is one of the processes that drives evolution and helps to explain the diversity of life on Earth..
What is the strongest evidence of evolution?
Comparing DNA Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
What humans evolved from?
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
How can you explain evolution?
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
Who is the father of evolution?
Charles DarwinAbout Charles Darwin: Darwin was born in 1809 and grew to become a naturalist, biologist and geologist who widely contributed to the science of evolution. He attended Edinburgh University for two years where he studied medicine, but quit later on.
What are the 3 types of evolution?
shows the three main types of evolution: divergent, convergent, and parallel evolution.
What is evolution in simple terms?
Evolution is a biological process. It describes how living things change over a long time. … It is known that living things have changed over time, because their remains can be seen in the rocks. These remains are called ‘fossils’. This proves that the animals and plants of today are different from those of long ago.
What is evolving in evolution?
If a population happens to have genetic variation that allows some individuals to survive a challenge better than others or reproduce more than others, then those individuals will have more offspring in the next generation, and the population will evolve.
What evolution can’t explain?
Evolution can’t explain complex organs Organs that allow detection of light could then have been favoured by natural selection, even if it did not provide full vision. These ideas have been proven correct many years later by researchers studying primitive light-sensing organs in animals.
