What are the similarity of fish frog bird and human embryos evidence of?

For example, fish, bird, rabbit, and human embryos are similar in appearance in the early stages. They all have gill slits, a two-chambered heart, and a tail with muscles to move it. Later on, as the embryos grow and develop, they become less and less similar.

What is the original source of genetic variation that serves as the raw material for natural selection?

Gene mutations provide new alleles, making these mutations the ultimate source of variation. A gene mutation is an alteration in the DNA nucleotide sequence, producing an alternate sequence, termed an allele.

What process drives evolution?

Natural selection is the process through which species adapt to their environments. It is the engine that drives evolution.Oct 24, 2019

What are several species that share a common ancestor?

Groups of interrelated species that share a common ancestor are called clades. Reconstructing evolutionary trees is an important step in learning the evolutionary history of species.

What are the three main sources of genetic variation within a population which is most common among eukaryotes?

The genetic diversity has three different sources: mutation, recombination and immigration of genes.May 19, 2021

Is the study of the similarities and differences in the structures of different species?

Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies.Mar 5, 2021

What do scientists study to see the genetic changes that occur through generations?

Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation.

Which mechanism of evolution is usually human induced and regulated by human preference?

Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
