Which of the following is true about individuals of the same species?
Individuals of the same species have the same inherited traits but different acquired traits, such as what they have learned and skills they have developed. Only these different acquired traits can cause differences in each individual’s chances of survival and reproduction.
What are the 4 main points of Darwin’s theory of evolution?
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.
What is the major concept of the biological theory of evolution?
The theory of evolution by natural selection, first formulated in Darwin’s book “On the Origin of Species” in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
What are the 5 pieces of evidence that support evolution?
There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.
What is accepted by scientists as evidence for evolution?
Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos.
What is the best evidence for evolution?
Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains.
Is evolution just a theory that remains unproven?
A scientific theory stands until proven wrong — it is never proven correct. The Darwinian theory of evolution has withstood the test of time and thousands of scientific experiments; nothing has disproved it since Darwin first proposed it more than 150 years ago.
What disease did Neanderthals have?
Neanderthal variants affect the risk of developing several diseases, including lupus, biliary cirrhosis, Crohn’s disease, type 2 diabetes, and severe COVID-19.
