Flashcards in natural selection Deck (20):
1

DNA

deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

2

Nucleotide

a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.

3

Chargaffs rule.

the cell should have a 1:1 ration

4

watson and crick.

they worked together on the studying the structure of dna.

5

Rosalind Franklin

Rosalind Elsie Franklin was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite.

6

Mutations

A mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.

7

Adaptations

getting used to something that you live around or a normal inviorment.

8

Species

A type of animal palnt or anything with dna in it.

9

evolution

The change of a species of something throught time.

10

Fossils

Bones of a animal.

11

fossil record

to refer to the total number of fossils that have been discovered, as well as to the information derived from them.

12

Charles Darwin.

he embarked on a five-year survey voyage around the world on the HMS Beagle.

13

trait

something that you get from aseaxual things.

14

Selective Breeding

is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

15

Natural Selection

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time.

16

generation time


In population biology and demography, the generation time is the average time between two consecutive generations in the lineages of a population. In human populations, the generation time typically ranges from 22 to 32 years.

17

Speciation

Speciation is the evolutionary process by which biological populations evolve to become distinct species..

18

Primates

A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines.

19

Hominid

a primate of a family that includes humans and their fossil ancestors and also at least some of the great apes.

20

Homo sapiens

is the binomial nomenclature (also known as the scientific for the only known extant human species. Homo is the human genus, which also includes Neanderthals and many other extinct species of hominin; H. sapiens is the only surviving species of the genus Homo.
