For future species in genome evolution, will we become the common ancestor for? Will another Homo species emerge?
Genome evolution is occuring and another species of human beings will emerge. But it will take millions of years for this emergence because the rate of genome evolution is extremely slow.
Scientists claim that on the basis of use and disuse of organs and survival of the fittest and some other evolutionary forces, the new species will have the following features -
Enlarged size of brain
Small size of body
Absence of organs like vermiform appendix, pinna, tail at embryonic stage etc which are of no use
Absence of little finger and little toe
Please rate.

What is the likely Homo ancestor for Homo sapiens, Neanderthals and Homo floresiensis? Create a possible phylogenetic tree for these three human species as they diverge from their common ancestral species.
Based on what evidence do we now think that Homo sapiens mated with other species of Homo , such as Denisovans and Neanderthals? a. Sequences of mitochondrial genomes show that there has been some introgression of genes from other species of Homo into Homo sapiens b. Partial genome sequences from Homo neanderthalensis and Denisovans (~15% of the genome sequence) began to show eviden ce of introgression c. Full genome sequences from bone fragments of "archaic" Homo species from Africa show...
A group consisting of a common ancestor and all of its descendants is a: A. Species B. Genus C. Clade D. Phylum E. Order
How did a genome evolve over time? Describe some of the common mechanisms by which genome evolution occurs (consider how individual species evolve new traits and how speciation itself occurs over time) What mechanisms have had the greatest impact?
Features shared by two or more species that were inherited from a common ancestor are considered_____? heterozygotes, derived, speciation, ancestral, or homozygous
A) The two species, along with their most recent common ancestor, constitute a clade 8) One speties is the descendant of the other 1. whidh f the olowingscie are comidered evolutionary sister groups?

Homologies (between different species) are anatomic characters which indicate descent from a common ancestor a. True b. False Select one: True O False
Until recently, there were two competing theories about the
origin of our species- "modern Homo sapiens". The first (single
African origin) is that all modern humans descended from a recent
ancestor in Africa, less than 200,000 years ago, and that our
ancestors replaced the archaic human species they found in their
migrations, including Neanderthals and Denisovans. (In the last few
years evidence from nuclear genomes of fossil humans has indicated
that there was limited interbreeding between the ancestors of
modern...
Bud eaters share a common ancestor with insect eaters. If an insect-eating species shares more phylogenetic traits with the vegetarian finch, what kind of phylogenetic relation do the two share? If a species of ground finch with variation in beak size suddenly had to all compete for large hard seeds, what kind of selection would occur on the species?
How can we use comparisons of DNA sequences, protein sequences, chromosome banding patterns, and genome sequences between different species to learn about origins and evolution?
