Galapagos finches have changed over time to get longer beaks to be able to eat the seeds on the island
The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.
Answer:
4
Explanation:
The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection according to Darwin's (and Wallace's) theory of evolution.
Natural selectionNatural selection is the process through which populations of living organisms adapt and change.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.Thus, we can conclude that The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.

Autosomal Recessive
Explanation:
The method of inheritance is autosomal recessive. Notice how the disease skips the parent generation. This indicates that parents have the recessive allele but do not express the trait. The individuals who are shaded in have two recessive alleles that were passed on from their parents, therefore they have the disorder.
