Detailed explanation-1: -Changes in both the biological and non-biological (abiotic) environmental conditions (measurable changes) cause evolutionary change. In turn, evolutionary change typically changes the biological environment, affecting species interactions, for example.
Detailed explanation-2: -Evolution is the change in heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every biological organization level. All life on earth shares a common ancestor known as the last universal ancestor.
Detailed explanation-3: -The Theory of Evolution by natural selection was first formulated in Charles Darwin’s book “On the Origin of Species (opens in new tab)” published in 1859.
Detailed explanation-4: -Sponges were among the earliest animals. While chemical compounds from sponges are preserved in rocks as old as 700 million years, molecular evidence points to sponges developing even earlier.
